Review: Sumiko Speaker Set Speaker


Category: Speakers

Wow, I just accomplished the single most impressive step forward in my system after 40+years of audiophilia. I had my speakers set using the system developed my Sumiko so that its dealers can optimize the set up of speakers they sell.

Those that remember me please forgive me for repeating my background, but on a forum like this there are always newbies that don’t really know the reviewers’ points of view, so let me give a little background as to my music and audiophile experience. I’m a financial consultant by trade, with over thirty-nine year’s experience, but I have over fifty-years experience as a “serious” musician. I’ve played trumpet since I was nine and jazz guitar since I was forty-two. I write equipment reviews (amps, guitars and speaker cabinets) for Just Jazz Guitar, play rhythm guitar in a big band and play trumpet regularly in churches, regional symphonies, brass bands (cornet of course) and even did a multi-year stint as lead trumpet in a funk/rock/soul band in the Dallas area. I hear live music all the time in tons of different contexts. For instance, on Thanksgiving eve I played trumpet with a large choral group and then had the pleasure of sitting there right next to a harp/oboe/flute trio accompanying the same choir. I’ve been really blessed to play in some incredible groups, including just recently, the Colorado Brass Band, one of the premier bands of the genre in the USA. I’ve played orchestral trumpet sitting with my back against the wall hiding a 32-foot organ pipe that massaged my whole body as I played. So, I feel and hear the music regularly.

I’ve really been serious about audio since my college days, when I bought my first Garrard/Scott/Jensen system. I moved to Time Windows/Bryston in the 1970s and 1980s and replaced the DCMs with Celestions mini-monitors in the 1980s. I’m just now finishing the first major system update since the 1980s. I’ve gone back to serious analog, recently adding a Pro-ject RM10 with Sumiko Blackbird through a Pro-ject Tube Box phono pre-amp. (I’ll do a review of the RM10 baby soon, including DVD-Audio samples, but that’s in the works due to technical challenges that I’m working through). This August, the Celestion SL-6 speakers were replaced with 4 ohm, floor-standing Vienna Acoustics Beethoven Baby Grands. Most recently I replaced the Bryston with a Conrad-Johnson CA200 control amp (see review).

Back to the speaker set, my dealer is Soundings in Greenwood Village, CO, owned and operated by Rod Thomson. Rod has several decades of experience in the audio business and is a true music lover. He’s been a dealer for Sumiko for a number of years and attended a several-day course to learn their “Master Set” technique.

When you read reviews of Sumiko-distributed speakers (Vienna Acoustic, Sonus Faber, REL and Sequence) you’ll often see the reviewer mention that someone from Sumiko came out to optimally place the speakers within their listening space. Michael Fremer mention it in this review http://stereophile.com/floorloudspeakers/506vienna/ The reviewer almost invariably will say something about how close the optimal placement was to what he would have used. Please remember that that comment is an ego thing, since it’s of interest to a reviewer to let the readers know that he knew all along how to set speakers.

Well, I’m humble enough to realize that I needed help. While my Baby Grands were breaking in I spent an hour or so every weekend moving them around, searching for a totally cohesive sound. Every other week I was tempted to move them back toward their rear wall, but every time I did it, I screwed up the all-important midrange. Not that the bass was always smooth. I’d get it sounding really good with “Ballad of the Runaway Horse” (same recording that Sumiko uses) but then I’d put on an orchestral piece and certain bass notes would pop out and overwhelm the music.

Still, the midrange was the most problematic to me. It seemed like when I got a really nice, deep, full bass that the mids would get congested and thick. Female voices would lose some of their character and the sound would seem to be thrown at me and be more piercing than I could enjoy. I found myself turning down the volume. Since I value accurate voice, accurate brass and imaging more than anything, I’d ultimately give up on the bass and move the speakers into the room until the bass stopped smearing things.

My self-derived set was actually very satisfying. Vocals were very coherent, full of nuanced timbre and the imaging had lots of depth and side-to-side accuracy. The Baby Grands had way more bass than my, now retired, Celestion SL6s, so I was pretty darn happy. Anyway, after I had a couple of hundred hours on the VAs it was time to call Rod for my Master Set. Generally, Sumiko dealers offer the set as part of the speaker purchase; however, as I understand it, not all dealers have the training. We’re lucky in Colorado, since Rod has the training and several years of hands-on experience implementing the technique.

By the way, skeptics are welcome. Rod told me he was a skeptic when Sumiko first came to his shop to show him. After decades in the business, he didn’t think there wasn’t anything he hadn’t seen or heard, yet he was floored by the impact. He does the set up for non-Sumiko customers for a fee. He told me of recently setting a pair of B&W 801 for a skeptic and the guy is now bringing in buddies from out of state to hear how amazing his system now sounds.

The process took about an hour and a half in my large room. Rod came in and longingly eyed the long wall with the fire place facing the Rocky Mountains. He said something like, “you could move this, move that and I guarantee you’ll be amazed with what your speakers do, OR I can put them along where you have them and get something less.” I thought about it. The WAF of the long wall was low, not because it wasn’t a good idea, but it wasn’t her idea. I thought, if I try my set up and fail, I’ll have to pay next time, but, what the hey, it’s only money. So I asked Rod to do his best with the placement that I preferred.

In a room that’s roughly 16’ X 40’ I was asking him to set the speakers on a 7’ wall, with a hall on one side and large, odd shaped entry on the other and a 40” armoire in the middle. The ceiling is 10’, BTW. The building is concrete, high rise construction with 10” slab floor and ceiling.

Anyway, Rod accepted the challenge and “The Ballad of the Runaway Horse” soon filled the room. I could attempt to reveal the whole process, but that would be futile. I witnessed the whole thing, start to finish, and actually helped a time or two and I couldn’t replicate it in a new speaker positions. I will say that he started with the bass, beginning with the speakers just a couple of inches from the rear wall and then moving them out an back while listening to the nodes. He worked the left speaker first, and then the right, focusing on getting the bass balanced between the two speakers, but with no nasty nodes in the midrange. Toe-in and rake angle were critical to the midrange and balance, but I think that getting the bass right and avoiding the midrange nodes was the single most important factors. Still, it’s a comprehensive system that you’re not going to be able to read about and then do. Listening and hearing the nodes takes some training. I was amazed to hear MAJOR changes with just ¼” of movement.

Bottom line, speaker placement is very sensitive to distance to the wall, speaker distance from each other and surrounding walls, speaker rake, speaker plumb (levelness) and toe-in. In certain circumstances the smallest movement can destroy the whole thing. On the right side of my setup there’s a wall angle that juts out at about a 45-degree angle. The smallest movement around that can screw up my set up.

Here’s one phenomenon that amazed me, the apparent volume of the system is about 1/3 lower. It’s not because the system has less sound energy, but because the harshness and phase anomalies are removed and it’s pleasant to listen at much higher levels. My C-J CA200 has a step-attenuator with 99 steps of .7 dB. I’ve never listened at 90 before yesterday. Stuff I listened to at 55 before is now at 70. Right now I’m listening in the background at 40 and that’s very coherent, but it’s low because people are asleep. Rod and I were actually carrying on a conversation as I had something on at 70 on the CA200’s LEDs.

The bass that I gained is mind boggling. I’ve listening to orchestral stuff and string bass stuff and I’m just blown away by the extension and clarity of the bass. My VAs ended up about a foot out from the wall, with about 3” of toe-in and 56” between the front toes. The image covers the whole wall. When I go into another room, the sound stays coherent and is actually louder at lower levels than before. Yes, a paradox. Up close, it sounds softer at a given level, but that sound travels further through the apartment. I suspect it’s because all inter-speaker cancellation has been eliminated, or at least minimized.

Now for the BIG PAYOFF, the mids are better than ever. I hear every little thing, in balance. My daughter put on a Brazilian CD that must have had 16 percussion instruments going, along with vocals and guitar. She couldn’t believe how much more she was hearing. I was hearing it for the first time and asked, “what’s that thing that sounds like a cross between a dulcimer, guitar and drum?” She’d seen a DVD of the group and said, “It’s something that looks like a cross between a dulcimer, guitar and drum.” The Brazilians apparently haven’t stopped making new instruments. Anyway, this recording was very dense, but with instruments spread all over the place. I “got it” 8 measures in.

This set up make light work of sparse studio recordings, like you might hear with Nora Jones. You hear each smack of her lovely lips, her Texas twang and incredible instrumental sounds. I loved the snare on one song, with the drum head a little lose and the snares a little tight. Wow, it sounded like one of my buddies playing snare at the end of my room. The voices in harmony separate into their individual pieces, yet you also hear the blend of the multiple voices.

Vinyl still sounds better than average digital, but I’m finding myself listening to more CDs on my poor little Oppo HD981. I think the removal of the distortions caused by the speakers made the digital distortions much more palatable. The midrange just falls effortlessly out of the speakers now. There’s no edge, beaming or other distractions (refractions?).

How do I measure this improvement? It was at least as good as going from the Celestions to the Baby Grands. Now I’ve got the bass extension of ported, three-way speakers combined with the imaging of sealed mini-monitors up on three-foot stands, pulled into the room. I’ve heard much larger speakers that don’t have the bass extension that I now have. It’s like I doubled the size of my speakers. I mentioned that the image covers the wall where the speakers are placed. The depth that I had with the speakers pulled out is still there and rock-steady.

What will it cost you if you don’t own Sumiko distributed speakers bought from a trained Master Set dealer. I don’t know. Sumiko doesn’t even mention it on their site. It’s better than if I’d spent thousands of dollars on equipment. It takes a couple of hours. I’ve paid lawyers with much less skill and training $250 an hour, so I wouldn’t flinch to pay $500 if I moved to another home and needed Rod’s help again. Think of this as another component purchase. Would you pay $500 for a good phono pre-amp? If yes, then this’ll give you several orders of magnitude more in system improvement.

Thanks for joining in. Sumiko has been doing this long enough that there's got to be more people on Audiogone that have experienced it.

I first experienced it in Soundings' own shop. I listened to the Beethoven Grands and thought that they sounded harsh. Rod said, "We'll setting those tomorrow morning, come back and they'll sound totally different." Well they were indeed transformed. That was for guys that had placed dozens of speakers in that room, using "the set" but they still had to go through the process with those particular speakers.

When I go over to the Virtual Systems sections I'm in awe of the equipment that many of our members have, but I wonder how many are truly hearing them to their fullest potential. Like I said, for my particular system, it was like doubling the size of the speakers AND still keeping the imaging of a really fine mini-monitor.

Please, those that have experience the Sumiko Set, please add your experience.

Dave, I wonder how "stable" the set up will prove to be. What if you accidentally move a speaker? Get new furniture? Change amps?
Yes, that's a very good question about stability.

I don't think that an amp change is a worry, but moving the speakers,even a little, is a concern. Moving the armoire would be a potential issue, but the other furniture is out of the sound path.

I'm using a laser-line, reference points on the baseboard, a ruler and a level to get them back into the exact spots. So far, so good, but I've only moved them back and out once so far. (When not in "serious" use, I keep them back next to the armoire, perpendicular to the wall and parallel to the armoire's sides). I practiced measuring several times before I made the first move and got my accuracy down to 1/16" repeatably. I'm careful to drive the spikes to the floor and level the speaker fronts.

If you had a straight wall behind the your speakers a large carpenter's square would yield repeatable results. One of my walls isn't perpendicular, so a square won't work.

I'll update in a couple of weeks to say how I'm doing after several moves back and forth.

Hi Dave, how could I have possibly missed your fab review of your Master Set experience?!

My Vienna Mahlers have also been set up via the Sumiko Master Set. . . in my case a joint operation by Rod of Soundings and Dave Ellington of Sumiko. My session lasted almost 8 hours . . . and they revolutionized the entire room. My listening loft is approximately 16 x 18 with a coffered ceiling peaking at about 11 feet. It is broadloomed and has a 12 x 9 very thick Chinese wool rug in the middle. Walls and ceiling are stippled. A 10 ft long wall unit sits against the left wall. Like in Dave's room part of this wall has also a 45 degrees cut (about 6 ft long). The left wall is essentially bare. A listening sofa sat against the outer windows along the outer long wall. The entire music system sat against a half wall along the opposite long side, which opens onto the 1st floor below. Just to make things a little more irregular, a 6ft passage way interrups one side of the half wall and goes to the stairs. I was proud of my own setup prowess. . . sounded good to me. After all. . . I have done music since I was 7. . . and I even attended Karlheinz Stockhausen's 50th Birthday Parti back in '75 in Paris. . . and once even shared a commuter train compartment with famed music critic Lorenzo Arruga, and used to build sand castle with conductor Antonello Allemandi when he was 5 years old, and last fall I even shook hands once with Albert Porter, and once even stayed at a Holiday Inn (Express). . . so, I must know what I am talking about. . . right?! Rod and David gently disagreed with the premises of my obvious qualifications, and explained that I was likely suffering of either low audio expectations or low self audio esteem blended with a very nasty case of narcisistic audio personality disorder. . . or in other words I was totally delusional. . . would I want to talk about it? Or should . . . they proceed to fix the room instead and forget about my hurt feelings? I huffed'n'puffed but opted for the latter . . . To start with, everything was moved around 180 degrees. . . I mean the couch went against the half wall, and the entire system was pushed against the windows. The wall unit seemed to be of no interest to them and was left alone. The left speaker ended against the beginning of the 45 degrees cutoff of the left wall,. The right speaker ended 3 feet from the right wall. Looked totally bizarre and asymmetrical. Connected the system and played the Ballad of The runaway Horse. . . which sounded just like a dead horse should sound instead . . . terrible and very dead! My feelings were now very very hurt. . . no more offerings of warm fuzzys from Dave/Rod. . . They continued to work. At 5:00 pm the setup was complete. Left speaker was 15.25 inches from rear wall. Right speaker was 17 inches from same rear wall, but had been pushed to about 1ft from the right short wall. Speakers were over 11ft apart. . . very asymmetrically arranged left to right, toed in for my couch 12 feet in front, spiked and raked to sonic perfection. . . . but I was in Heaven. At 5:30 we piled into David's car and went to Austin Airport. . . I left for L.A., Dave left for Houston, Rod flew back to Denver. . . now I am back home in Austin and I still am in Heaven, and my feelings are no longer hurt, and I no longer need any warm/fuzzy talk therapy from them.

Jesting aside, reading Dave's discussion of the effect of the Master Set process is exactly bang on. The sonic effect on my system was simply uncanny and likely comparable to a significant component upgrade. I suspect that in most rooms there may be more than 1 set of optimal nodal points that could be hunted down, if time and patience were of no concern. . . some more WAF friendly than others. . . my wife has approved of the new looks of the music loft, and has at least once told me she liked the music I was playing, she did not even realize that the volume was rather very much louder than usual. . . that's a real first!!!

I have asked Sumiko if any of their local (SF Bay Area) dealers would hire out and perform a Master Set for me even though I have not purchased speakers from them and don't own any Sumiko speakers. They've tried to find someone, but so far, no dice.

I've played around with the "Iron Chef Speaker Setup" from AA, which I think is the Sumiko technique. Though I have had some success, it's hard to do from written instructions.
