How Can You Get Big Sound in a Small Space? – Part Two

Fascinating Transformation in a listening room that sounded noticeably less than excellent, on the first go around!

I learned so much from the experience and from Ed Masterson as we (Ed, Miguel and I) began conversion of this room, set up the gear in the room, mildly acoustic treated the room, tested this room and got so-so results in Round 1 of this room.  And then there was Round 2…

THINK ABOUT THAT FRUSTRATION WHEN YOUR MUSIC LISTENING ROOM DOESN’T SOUND RIGHT.  OR WHEN ANY PROJECT DOESN’T APPEAR TO GO RIGHT. WHEN YOU JUST KNOW (or at least hope) IT COULD BE OR SOUND BETTER!

So, the purpose of this story (Part 1 and 2), is to share an experience about how a listening room that sounded quite horrible at first came around to one of Audiophile excellence. And how a willingness to explore, experiment and be teachable through a bit of Audiophile Cross Fit and Persistence will grant you the rewards in the end of a phenomenal Audiophile Listening Room.  Well, that and someone with a great deal of knowledge from Experience,  Engineering and Audiophile Passion as that of Ed Masterson.

IN PART ONE WE STARTED OFF WITH:

I CAN’T GET THE MUSIC TO SOUND RIGHT IN THIS ROOM!

See Part One here, please see the blog post here.

So to recap from where we left off in Part One:

We did finally get the room tuned in on the South wall with the Wilson Audio Tune Tots speakers, with the NAD M10 Streaming Amplifier and the REL Acoustics T7i Sub-woofer pair to fill in on the base High Level (not LFE), as the t7i’s do go down to 30 hz.  The room sounded fairly good with all the gear setup on the South wall of “The Office”.  But not great.  

So, Ed Masterson canceled our event (our Annual Music Appreciation Event), and decided to experiment with the room some more.

Part Two – How Ed Transformed the Entire Listening Experience in our new “The Office” Listening Room

What would make someone take a nicely set up listening room, that sounds decent, has a nice visual appeal, and then completely redo the room like a wrecking ball?

Someone with a lot of passion and I’ll even toss in the word pride, for how his listening rooms sound when completed. Be it a customer’s home, or one of Ed’s and Our listening rooms in our Audible Images showroom, Ed just wants to get it right.  (See Ed’s approach on our AV Dream Designs page here and the YouTube Testimonial & Approach video here.)

So maybe it was the following weekend after we got the pseudo-tuned room completed that Ed decided to re-arrange.  The room is like 11 ft x 10 ft, and now the equipment would be moved to the 11 foot wide East wall, from it’s former position on the south wall.

It’s actually a much more beautiful view having the gear all placed against the East wall of the room.  It’s a very tropical and artsy feel around here anyhow (our showroom is in what is called the “Eau Gallie Arts District” or EGAD, an area in Melbourne of antiquity and fine art), with some really stunning estates across the street.  And if you really know to look for it, you can see the Indian River through a little corner in the upper right of the neighbor’s property across the street. Occasionally you can even see sailboats anchored in the water behind the house. I’m getting off on a tangent here 🙂

Back on point, the move did give us a few more inches of breathing room (about 6 more inches on ea. side) for the speakers.  Ed set up the same gear, the Tune Tots, M10 and the REL T7i’s with the high level connection. (Note: REL Acoustics provides a very unique, easy to setup, 3 pre-stripped wire connection to the speakers with the Speak-on connectors on the other end that go into the high level connection on the back of the subs, specifically for 2 channel listening.  They also have an LFE connection for a surround setup)

Ed did all this over the weekend.

When I came in on Tuesday, to say I was blown away would be an understatement.  The base was clean, fast, we had a great soundstage, the tonal balance, perspective, were all good and most of all, the listening experience had you melting into total voluntary aural submission in the chair.

Over the next week, Ed did some fine tuning with the room, not to much more of moving gear around, maybe a little, but then he focused on adjusting & lowering some of the wall art canvas pictures to tighten up not so much the base now, but more on getting an even clearer audio image of the different instruments in the mids and highs.   

The room was now ready for our Music Appreciation Event.

Experimentation with Additional Amplifiers and Speakers

Over the next month we started experimenting with a number of speakers and amplifiers, and following the NAD M10 success, we then brought in the Parasound Hint 6 integrated amplifier (a nice sounding piece with versatility too) to hear with the Tots.  Very nice.

Then we brought in the Dan D’Agostino Momentum Integrated Amplifier (which if you have never heard one, is well worth a 100 mile drive to just come hear) and we began to discover that this room, this ridiculously small room was actually quite astounding sounding. The Tune Tots with the D’Agostino Integrated Amplifier and the REL T7i’s for bottom end sounded absolutely amazing.  We then moved the NAD M10 and Tune Tots into our front showroom so folks could hear it out there when they first walked in the door.  Not because we were kicking them out of the room.  We were on a high, just blown away with how good this room was now sounding.  You could say we were in tunnel vision just to hear all the possibilities of this room.

Then we started testing the Wilson Audio Sabrina’s with no subs.  There was actually not enough room for subwoofers beside the Sabrinas.  I heard someone say, that the Sabrina’s, with the dCS Rossini DAC & Player and the D’Agostino Integrated was kind of overkill for this room.  And he was probably right, lol. But it sure was fun finding out that we could put Wilson’s smallest floorstander in this room and hear that Wilson time alignment magic force you into a semi catatonic drooling a little bit listening state 🙂

Now it was time to give the room a Sonus Faber makeover.  We setup the Sonus Faber Sonetto III’s paired with the REL T7i’s, and yes, that sounded excellent.  But I believe the anxious moment was to hear the Olympic Nova I’s in the room, and paired with the REL T7i’s.  They sounded quite awesome, and we also decided, (well Ed decided) that the Olympica’s needed a more closely matched bottom end partner.  The T7i’s are excellent, but they are modest priced subs, and an upgrade in subwoofer was needed to match the lower bass and quickness that one would expect with a higher end sounding speaker as the Olympica Nova I’s.

I know I need to close out this article but I have to share a couple other discoveries of what could be done with this mere closet size of a listening room. 🙂

So, Ed decided that an appropriate upgrade in subwoofers for this two channel setup was a pair of REL S/510’s, and that is when I believe we hit Nirvana (and that is a word I do not use).

OMG, the sound of the Olympica Nova I’s was as good in analogy as the entire Visual and Audio culture that Sonus Faber creates with their speakers in how they are designed to look (lute shaped) and sound like the famous violins made in Italy. Those Olympica speakers that we knew were magical when we tested them out during a demo from Woody our Sonus Faber & McIntosh rep, even though the room itself sounded horrific back then, paired with the newly arrived REL S/510’s matched with the D’Agostino Momentum Integrated Amp and the dCS Rossini DAC & Player was just flat out beautiful to the ears.

You have got to come in to hear this room and these audiophile magnifico speakers. I’m in one of those justified moods using over the top hyperbole.

Lastly, this past Friday, we had our Olympica’s out on loan to a friend, and I asked Ed if we could setup the Sonus Faber Guarneri’s in the new location.  I laugh, thinking back as to how bad they sounded placed on that south wall a few months ago.  The muddiness that was unacceptable to even someone who hates listening to music.  Now with the Guarneri’s on the East wall, we haven’t even connected the REL Acoustics S/510’s yet. (And we almost always have REL subs connected to 2 channel listening, because it allows you to literally hear all the music the artist intended) We got the Guarneri’s setup, roughly tuned in, no subs, just Sonus Faber Guarneri’s on stands.  

The result was a Reward of Irony.  The Guarneri’s sounded absolutely beautiful.  The tonal balance was just right and the spaciousness of vocals, piano, saxophone had a bloom so clean and layered you couldn’t help but smile, and the images were very focused and crisp. And the base was very good, no mud, just appropriate quick accurate base.

An excellent Audiophile experience of Italian excellence.  I mean, everything sounded special in this new room.  And this combination of gear and placement which included the Guarneri’s, D’Agostino and Rossini (even though it’s made in England, it sounds Italian 🙂 , is a culmination of effort that provided us smiles.

Come in to hear it.  Just Enjoy the Music.

Moral to the story, if it doesn’t work the first time, try again.  If it doesn’t work the 2nd time, Call Ed…

Thank you for stopping bye.

Detailed Summary of Lessons Learned Bullets

  • I will be expanding on these bullets in the future. I am anxious to get this story live, but I’ll be back to expound upon what Ed did to transform a room from Dud to Dynamic.
  • Go and Listen to a couple of Listening Rooms like in our showroom to establish a “Reference” of what excellent sound is and can be.  So that you will know what to strive for based on your budget and listening preferences
  • Don’t get stuck on your first or even second room configuration or layout. Sometimes issues may exist that you are unable to see or notice early on.
  • Speaker placement. (will be covered here)
  • Almost a necessity for Subwoofers to be added for two channel listening
  • Room Dimensions and Approach
  • Knowing how to describe what you’re hearing
  • Acoustic Treatment, how to approach it and how it refines but not necessarily defines how your room will sound
  • Matching Gear correctly
  • Asking for help

NOTE: This bullet list I am going to come back to and not only add the details it, but also refine it.  I just wanted to get Part II published and out the door, because it was just so amazing to hear and experience.

We enjoy being your go to source for all Your High Performance to Ultra High End Home Stereo two Channel systems, Modest to Ultra High End Home Theater home entertainment systems.  We also enjoy Audiophiles just dropping in to talk the hobby, ask questions and even pick Ed Masterson’s brain on questions about your system and also about used and pre-owned gear sales, including in which we are also an authorized Audiogon Dealer, to help move your former gear as you pursue upgrading thoughts that you may have now or on down the road.

E1 Isolation Base – Removed noise in a Night and Day Comparison for a turntable

We just got this HRS E1 Isolation platform in for people to hear the noise reduction in more modest systems. (This just happens to be the only system that we could try it on 🙂 )

A customer friend of ours used our platform and heard the noise drop out on his $1600 Project turntable. Dramatic noise drop.  He was blown away.  So I had to test it out for myself, the next day when I got into work. 

Jaw dropping is how I describe my personal observation in the noise reduction here on the MT5 turntable when I loaded the Eric Clapton – Unplugged album.

As soon as I dropped the needle down on “Hey Hey” with the platform, you actually didn’t hear the main noise of needle drop you normally would. 

Then Ed Masterson, played “Signe” the 1st song on the album to hear the noise from the crowd clapping in the concert. The soundstage of clapping went from stadium wide, not because that was the actual width of the soundstage, but more because it was one aspect of the recording that perhaps was not as coherent as the instrumental  (felt like it) and opened the reproduction to a very distinct width and natural soundstage. (When I looked up the background on his “Unplugged” album, I discovered Unplugged is a 1992 album by Eric Clapton, recorded at Bray Studios, England in front of an audience for the MTV Unplugged television series.)

The noise floor just dropped out, the high quality recording become distinctly more transparent, airy, natural and so many other terms of clarity I could use.

A Note I’d like to Add; Before I wrote this blog post about my own personal experience. Having been an Audiophile for less than 3 years, I wanted to read from another person’s perspective in regards to noise reduction and specifically if I could find, an article on an isolation platform. In my search I found one from the best, a very interesting and relevant point made by Robert Harley, Editor in Chief of The Absolute Sound Magazine, (and author of the book I am reading called “The Complete Guide To High-End Audio“) in an article he shared in 2015 called ‘Critical Mass Systems Maxxum Amplifier Stand Disappearing Act’.  I quote Mr. Harley below from the article:

“In my editorial in Issue 246 (“The Law of Accelerating Returns”) I suggested that the goal of assembling the most realistic-sounding audio system is best realized by investing in products that are demonstrably more transparent and resolving.

All too often, audiophiles swap components only to trade one set of colorations for a different, perhaps initially appealing, set of colorations. Years of such “upgrades” don’t bring you closer to musical realism in the long run. It’s better to spend your money on components or accessories that improve the sound without any sonic tradeoffs.”

During our test, Ed made the comment that being an electrical engineer, this platform made more Engineering sense than other noise reduction/isolation products or methods, because it was based on applying mechanical noise reduction. So, I stayed the course on my post here.

My summary: It was very much a Night and Day difference.  Two turntables were tested.  The first one was a $1600 Project turntable and the second was a $7000 one.  The same friend/customer Dave heard both. And from what I understood him to say, was they both had about the same results. An $1100 isolation platform by HRS did this.  Very simple test. Amazing results.  I encourage you to come in and hear what I did.

The gear used:

The McIntosh MC462 Solid State Amplifer, the McIntosh C2600 2-Channel Vacuum Tube Preamplifier, the McIntosh MT5 2-Channel Precision Turntable, and Sonus Faber Olympica Nova III Floorstander Speakers with the REL sub-base woofers turned off. (because one happened to sell the other day)

Tuning a System is not all Black & White

If you’ve ever been around or spent time working or hanging around a passionate experienced and engineer Audiophile then perhaps this post will give you a few grins. Not because I am humorous or gifted in writing , no, in fact I’m just learning how to write about this stuff. But the grins, they’ll hit you because you are or do know an Audiophile who has this kind of Passion to make any sound system he touches to sound the best that it can possibly sound. And as the title suggests, tuning a system is not all black and white, not some simple check list to follow.

Ed asked me to go along with him to this customers system tuning. The goal was to tune a pair of high end REL Sub-base speakers to a stereo system already tuned for a pair of Wilson Audio Sabrina’s. I learned a lot from this day, so here we go.

The Question: How does one go about tuning a customers system, especially one that is not in an ideal, acoustically treated room? What methodology ought to be applied? (the featured image above shows the Wilson Audio Sabrina’s and the REL G1 Mark II Sub-base/sub-woofers, with the electronics in a concealed cabinet in the wall to the right)

Scenario: I went to my first customer system tuning session by Ed at a home that had a pretty high end system. And the setup was in a living room with a scenario that was not necessarily ideal for achieving optimal sound for the system. What do I mean?

Room Description: It was a beautiful living room, black & white decor, with some stunning natural wood pieces of furniture to accent the black and white tones. Ceramic tile floor, and an entire wall of glass (sliding doors) facing a pool/patio area. Flat Ceiling around 8 feet. Many reflective surfaces including Black & White photographic imagery of the other famous b&w photographer that would make one think of Ansel Adams, if he or she was not well schooled in the work of the two artists.

So, I’ll ask the question again, how does one go about tuning a fairly high end home Audio system in a somewhat hostile environment in regards to getting the best acoustic sound results, and walk away satisfied?

Note to whom might be new to the Audiophile world. Adding a pair or even a single sub-base/sub-woofer speaker to a 2 channel stereo system adds a fuller, more extended, and more dynamic bass range for a stereo system. The Wilson Sabrina’s do an excellent job with the 8 inch driver for bass down to 31 hz, however, by adding a sub-base speaker pair to the main speakers enables the listener to enjoy the bass extension deep into the 20 hz range, but more importantly, this allows the Sabrina to breath more within it’s design range, and let the recordings have their freedom should they have bass that is hungry for that 20-30hz region. (the G1’s do go down to 15 hz, though technically, the human ear I believe to around 19 hz)

I digressed a bit with the above, so back to our Audiophile Dr. approach if you will, to take this environment and bring the potential of the Speakers to their best possible sound in the room. Note: The Wilson Sabrinas were already tuned in by Ed on a previous occasion, but today’s tuning was to blend/tune the pair of newly added REL G1 Mark II Sub-base speakers into the system.

The Gear: The electronics are a McIntosh MA9000 Integrated 2 channel Amplifier (300 WPC). Speakers, as mentioned above, Wilson Audio Sabrina’s and REL G1 Mark II Sub-woofers. The source used was a streaming digital Bluesound unit that used the DAC built into the MA9000, even though the Bluesound unit actually does a surprisingly well job with it’s own built in little dac.

SEE PHOTO GALLERY BELOW.

So I was there for an observation experience only, and just watched and listened to Ed as he submerged his Audiophile listening ears to merge the REL’s with the Sabrina’s within this challenging “resonant rich” room. 🙂 Miguel assisted by changing settings and positioning, as they were shared by Ed.

With Ed Masterson, he approaches tuning a system from a more right brain aspect. He doesn’t let himself be dictated by numbers and settings, per say, but more, his approach is all about the listening. Listening for Tonality balance , phase timing, clarity & extension, airiness, etc. This requires getting up from the center “Sweet Spot” seat, making adjustments, and sitting back down. And, because Steve and his Wife do a lot of standing, Ed also kept checking the system from standing at the very back of the living room, close to the kitchen. (one of the photos show the depth & size of the living room) I’m just gonna go ahead and say this. For the most part, Ed is for the most part against “Room Correction or Eq Systems”. Bass tuning software, different story. Generally speaking, Ed is a tuning by listening first, not graphs and numbers etc. But, he does remain open minded to hear about new methods 🙂

It was amazing actually to watch Ed work. Word to the wise, Don’t interrupt him, unless he glances around asking for thoughts. He’s tunnel vision. You will break his flow when he is hyper focused in a tuning session. So, he started off, by listening for the timing or phase of the subs with the Sabrina’s, to make sure the subs were adding and not canceling out any of the low end sound. If the drivers are pushing out on the main speakers, well, you want the sub-woofer to be in phase with the speakers and be pushing out also. At the same time, it appeared he also addressed any bloating or excessive base that seemed to be apparent with the subs, simply because they had not been tuned yet to the room. This he addressed slowly over the next 1.5 or so hours thru constantly re-positioning the subs, fine tuning the volume, the crossover settings as he brought these two piano gloss black beauties into harmony with this awesome system that Steve and His Wife owned.

Once Ed finds the spot, where the REL’s really seemed to energize the room, having that very deep extension, and pressurized the room, then he seemed to go into fine tuning orientation angle of the subs, tweaking the volume, the crossovers. As he’s doing this, Ed always uses his chosen 10 or 20 tracks to determine certain things or nuances in those songs, and whether the speakers are delivering those sounds, (and not hiding or canceling out) and within the correct sound stage width and depth. We seemed to be getting close after an hour or so, but something was eating away at Ed’s thoughts, and it just didn’t seem like he was going to address it with the movement and settings adjustments that Miguel had been doing so far as per Ed’s requests.

Then an idea out of left field hit Ed. (as it appeared to me) Now normally, most of our high end speakers and amplifiers (speaking as a newer 2-3 year Audiophile) are set up in 4 Ohm on the amplifier out setting. As this was the case with the MA 9000 McIntosh in Steve’s system. But Ed asked Miguel if we can experiment with the Amp, and connect the speaker cables to 8 Ohm out. This took an extra 15 or 20 minutes to change over. A wall board panel had to be removed with the drill so that the entire gear rack could be spun around in order to make the changeover to 8 Ohm to the speakers on the back of the integrated amplifier, instead of 4 Ohm. Once this was done, any remnants of weightiness or heavy bass had disappeared. (As I strive to learn Audiophile jargon thanks to the help of Robert Harley and his awesome “The Complete Guide to High-End Audio – 5th Edition”), I can’t help but express that when that magic base popped, and had energized the room, the mid-range also seemed to expose more of it’s awesome timbre and clarity along with the treble. With another 10 or 15 minutes of fine tuning, Ed was happy. Then, Ed began listening to some of the tracks that Steve and His wife like to listen to, to make sure that these also sounded excellent.

On a final note, by switching the output over to 8 Ohm’s, it may have reduced a small amount of the base punch that would be more apparent at 4 Ohm’s, but Ed knew, that while he was tuning, it is always best to turn off the Equalizer (Frequency settings controls on a Mac which have 8 adjustment knobs from 25 Hz up to 10 kHz). It is made to have it on or off, depending on the listener. But for tuning, you definitely want it off. But now, if Steve wanted to increase the punch of the base or lower midrange, he could easily turn the Equalizer on the Mac right back on, make his frequency enhancements, and it would not accidentally alter or change the physical tuning that Ed and Miguel had done in the last couple hours.

In just an hour and a half to maybe two hours, Ed had turned this two channel stereo system with the new addition of 2 REL G1 Mark II subs into a very nice and powerful sounding system in what was a potentially hostile room for resonance issues with all the glass doors, piano, glass picture frames, ceramic floor, etc, for the Wilson floorstanders and/or the subwoofers. This, is Ed’s passion, and was a great learning experience for me.

Quick Takes with Ed Masterson: Noise Issues – Part 3

Whenever we look at reducing noise in an Audio (stereo) system, it’s because in the end, we want our sound quality to go up, Right?

So, when we take a look at some high end gear, as Audiophiles, and we ask the question, why do they have a separate Power Supply from the Amplifier, in Dan D’Agostino Master Audio Systems electronics?

It comes back to the fact, that noise is everywhere and it is an enemy of the audiophile. Noise gets into a system in components, cables, RF and many other ways.

In this excellent four part series Ed addresses noise with some great tips on how to eliminate it. And here in part 3:

Enjoy Ed’s explanation as an Electrical Engineer Audiophile, regarding some of the components in high end gear, why some components are separate and their purpose in Audio electronics, so that you may gain some powerful insight.
