Every time I write one of these show reports, people remark about how I must have thought that the show sucked.

It is like, because ours are one of the few show reports that says something about the sound - specifically the descriptions about good sounding rooms and not so good sounding rooms - and with the abundance of all those 'feel good' show reports - it makes these look plain unhappy in comparison.

But, in fact, we like going to shows, though some better than others because of the quality of the sound in the rooms. Ranking the shows:

CES has the best sound, and some awful sound.

Montreal has a lot of good sound and some awful sound

RMAF has a lot of good sound

Stereophile Shows have some good sound and a lot of not so good sound.

Although many people told me about rooms that sounded awful at RMAF this year, in my tour through, I think, just about all of them, I did not have shut down my ears during any of my photos. Now, it is true that I did not take as many photos and therefore did not have to stay in any room for very long - but still, I think that the trend for the worst sound at shows to be slowly improving over time is still in existence.

Because we exhibited at this show there was not a lot of time for photographing and listening to all the rooms at the show. Even though we made a modest attempt here to cover what happened - you will notice that the quantity and quality is below that of our other show reports (for example, our recent CEDIA show report has over twice the number of photos this one has).

Also, it is sometimes depressing to write about what is wrong with all the systems that have major problems. Sometimes, the hype that a particularly poor system is the best thing since Edison invented everything stirs up a need for a countervailing blow for the truth, but in general I prefer talking about systems that sound good (although I like photographing everything and making them look as awesome as possible in Photoshop, all equipment is great looking, to my taste - it is just that some of it you just don't want to ever plug in).

I like writing about very inexpensive systems that are (much!) more enjoyable than most of the big boys, like Almarro (sometimes), Odyssey Audio, the Star Sound Caravelle loudspeaker, the Acoustic Zen Adagio speaker (which we now carry) and little Audio Note U.K. systems (which we carry).

I like writing about the expensive equipment that rocket the listener to wonderful new mental states of mind - most of which we now carry, albeit with a few exceptions because other local dealers carry the lines.

And lastly there is the new equipment with much promise now being developed like the Cogent True-to-Life horn speakers.

It is fun to listen to 'the good stuff' and it is fun to write about it. The other stuff is not fun. If there weren't so many people, mistakenly or not, often in the industry, saying how great some of the uh, equipment that is not likely to have a wide appeal, sounded, all of my show reports would be happy happy and the people with rooms that did not sound good could work hard in peace to get it better next year.

But nooooOOOOOOoooooo.

You have people who have no care or concern about what good sound is pontificating this and that for all sorts of reasons unrelated to that of helping people find and build systems for themselves that they will like. There has to be someone who speaks out against all the nonsense - right now it appears to be us (and I am purposely ignoring and will continue to ignore those whose profession and popularity stems largely from, seemingly, proclaiming that everything is nonsense, whether it is or not).

So, even though this report is a little weak, because of time constraints, at this time with respect to the Defense Against the Dark Arts of Audio Obfuscation, we will be back in full force at the next show if all things go as planned.

And of course, in the meantime, there is always the blog.

Oh, Best of Show: The Kharma* Midi Exquisite / MBL room. [Even though I think our two rooms were better, it is hard to be impartial, so it is easiest to just exclude our rooms from the running altogether).

The parts 2, 3, and 4 of this report have mostly just photos, a little commentary, and the names of the companies sponsoring the room. If you want to know product names and prices and stuff, as usual check out Dave and Carol's reports at Positive Feedback (scroll to the bottom).

 

 

 

 

 
This is the main Audio Federation room. We also had a smaller room with an all Audio Note system. For the main room this year we brought the Marten Coltrane Supreme loudspeakers instead of the smaller Marten Coltrane speakers that we brought last year. A full list of what we brought is here: Audio Federation's RMAF 2006 equipment list.

 

 

 

 
One of the most frequently asked questions was: "What does that big box in the middle do?" Followed by "Which, out of all those boxes, are the amps are driving the speakers?".

Well, the big box in the middle comes with the speakers. It has two built-in 2000 watt (into a 4 ohm load) amplifiers that drive the two bass towers that handle all frequencies below 100 Hz. It also contains an active crossover.

The other boxes are the pair of Edge Signature One solid-state amplifiers and the pair of Audio Note U.K. Kegon 300B SET amplifiers. These other amplifiers drive the main towers which handle frequencies above 60Hz. During the show we mostly used the 22 watt Kegon amplifiers.

 

 

 

 
Here we have the side view. The speakers were pulled out from the wall a bit, as the Coltranes were also last year, to avoid a bass anomaly that occurs in this room closer to the wall - I think because the wall juts out a little bit on the left side (not visible in this picture).

 

 

 

 
This year we showed with a pair of Harmonic Resolution equipment racks - one silver and our gloss black one from our showroom. We wondered if it would look finny to have two different-colored racks next to each other, but after deciding to put the silver components on the silver rack it - well - it came out really nice we thought. The two different colors kind of highlighted each other.

 

 

 

 
As you all know, optimizing the allocation of space on an equipment rack seems to take either a super-computer or a lot of luck. Here we have the Emmlabs CDSD Signature Edition transport on top and the Audio Note M10 line-stage below it. Then we have the Emmlabs DCC2 Signature Edition DAC and on the bottom one of the two Galahad power supplies for the M10.

Everything has 3 HRS Nimbus Couplers / Spacers to couple the component to the rack in order to further tame bad vibrations. Except, that is, the two M10 power supplies, which were too tall, and were in too tight of a fit, to allow room underneath them for the Nimbuses. Guess we left our super-computer at home.

 

 

 

 
We played vinyl on the Brinkmann Balance turntable, which we ran through the Lamm LP2 phono peramplifier. In between the racks we squeezed a Shunyata Hydra M8.

 

 

 

 
The Audio Note Kegons drove the 93 dB efficient speakers very well. It helped that they did not have to deal with frequencies below 100Hz. And even though the power for the low frequencies was handled by that humongous box in the center there, the lovely natural bass that the Kegons can produce still showed through - I guess a lot of the character and shape of bass notes comes from frequencies above 100Hz.

There were some concerns about the amps clipping at very high volumes on very dynamic pieces. Personally, I will take quality of sound: emotion, sophistication, magic, realness, naturalness, over the ability to play 'at any volume'. I mean, we (Neli and Leif) played this system LOUD. Louder than rooms I typically like to go in when I attend a show. Funny, no matter how loud a system is there is always someone telling me that they listen to their system 10 times as loud - which is not to say that they actually listen to it that loud (which would take 22 times 10 to the tenth power watts which I think requires hooking up their system to the Sun) but that they want to be able to listen to it that loud.  Many of these people suggested we bring a large solid-state amp to the show next year - and we do have the 800 watt Edge Reference 'pyramid' amplifiers that we brought last year... :-)

We had Jorma Design 'Prime' cable in the main tower speakers and their 'No. 1' cable on the bass towers. 'Prime' is used internally to the speakers, but we did not have enough Jorma 'Prime' to put on the bass units. All-in-all we did not notice any problems with this slight lack in symmetry to the cabling - but then again we (Neli and I) had not heard the bass units with the 'Prime' cable, otherwise I think we would have been really jonesing to have Prime for both runs of speaker cable.

We used a 10 meter run of Nordost Valhalla interconnect to get the signal from the racks to the amps.

 

 

 

 
Here we are playing a Bach Cello piece on the Emmlabs. What music to play at shows is certainly a hot issue, especially when visitors to rooms at shows must necessarily make snap judgments about whether to stay, or even enter, a room because of the limited amount of time they have and the large number of rooms they have to see - a judgment often based largely on whether they like the music currently being played... or not.

There is some discussion on this topic by a number of people on the blog: Positive Feedback's comments on our rooms

 

 

 

 
Both the M10 line-stage and Coltrane Supreme loudspeakers were only played about 100 hours before the show (the drivers in the 'Supremes' had also been run 500 hours in a special stand-alone break-in process at the factory).

I am not sure what effect the newness of the M10 had, but the speakers did have some reticence in the mids and upper mids, as one might expect, sometimes causing the upper mids to sound a little hard and evidencing an overall compression to transients in these frequencies.

During the 4 days that we played them at the show - the speakers sound changed radically. In the first few days, before the show, they changed from hour to hour. In the beginning there was an obvious harshness to the upper mids and lower treble that was just about completely gone by the end of the show - finally occurring only once every hour or two. Personally, I think it is amazing that after only two hundred hours of play, that they sounded so good - we usually recommend 600 to 1000 hours of break-in for speakers.

Before the show, we had some concerns whether these speakers would be able to fill the room with sound - especially compared to some large horn speakers with which we are quite familiar (OK, yes, the Acapella Triolon Excalibur). We like that BIG sound and we were hoping these would also do BIG. Within about 5 seconds of the first CD we played on the show system Neli and I looked at each other with big smiles - these speakers do BIG alright, and in a more controlled, frequency agnostic fashion, with greater resolution in the mids and bass, with more slam, but sacrificing an acceptable (to us, and I think we are darn picky) amount of purity in the treble to the plasma tweeter.

A lot of people ask us the $250K question: are the Coltrane Supremes better than the Triolons? Is the Grand Canyon better than Yellowstone National Park? The question is kind of meaningless unless one defines exactly what one is measuring when one compares these two giants. We can say that we are VERY happy and we are looking forward to many, many years of hearing music through what, yes, are the best all-round speakers we ever heard.

 

 

 

 
Audio Federation's Audio Note room.

When I first placed the speakers and rack, I was concerned that the corner on the right there was not a real corner (the speakers like to be in a corner) and that the heater unit there behind the right channel was not really a wall. I wondered if Dave Cope, who is the Audio Note rep and who was playing music in this room most of the time, might change the configuration to the long wall, which had two real honest-to-goodness corners. He was probably thinking like I was that there really wasn't a heckuva lot of time to be messing around trying things out - and if the short wall worked - let's just stick with it. Often the most important thing is not mucking with the room but to warm up the system and to keep it warm.

A couple of different cartridges were used during the show, including an AN S4 step-up transformer. Neli was present and helped run the demonstration during which the differences were apparently very obvious. Me? I absconded with the two Kageki 2A3-based amps from this room and put them on the Marten Coltrane Supreme loudspeakers in the other room. You can read more about this here: Junior Mixibitor fun with Audio Note Kageki.

OK, here it is. What y'all been waiting for.... Our solution to the fake-dear-horn-in-the-eye problem. Yes, they ARE most of them at eye level. By demonstration we learned that some are so accurately placed that they can knock out two eyes at once. So, not only are they kind of grotesquely ugly, they require condoms as well (we thought real condoms would not be quite the right thing in this situation... YMMV).

 

 

 

 
The Cogent True-to-Life loudspeakers, Welborne amplifier room.

This room was a disappointment for me - and after recommending this room before the show to many people. I hear tell that the sweet spot sounded pretty good, but even though I was within a few inches of the sweet spot (the chairs were such during my second listen that no one was able to sit in the sweet spot) it just sounded like any ole speaker to me. It didn't have that magic and separation and natural bloom that I have heard before with these drivers and this amplifier.

These speakers look a lot nicer than the old square white ones but the old design, using the same (or worse) amps, had a wonderful sound, even far outside the sweet spot. See our reviews on location: and at the last CES show: The Cogent True-to-life Horn Speakers at CES 2006.

Just goes to show how every little thing is important - that having great drivers like the Cogent field coil compression drivers is not always enough.

 

 

 

 
 

 

 

 

 
 

 

 

 

 
 

 

 

 

 
How cool is this? I always think reel-to-reels are going to fall over, being usually tall and skinny. But this, ... I want one. Seemed to be a significant step up in sound quality over the turntable - but it is all unfamiliar cabling and cartridge and so on, so on an absolute scale I do not know just how good this sounds. And controlling vibrations might be an issue. And the color may not fit into your listening room's color scheme... but don't you want one too?

The Gamut setup was in a large room, a very, very large room this year. While it did not pressurize the room by any means, nor did it have much bass, it did not sound strained and it did fill the room better than one might expect.

 

 

 

 
 

 

 

 

 
The IsoMike room at this show used twelve (12!) 9 foot tall SoundLab* electrostatic speakers is a really large (60x60 foot?) room. Driven by Pass Labs (and later some Rowland) amplifiers with a Emmlabs digital front end.

Without something warm in the system it was quite cold and impersonal sounding, as expected. Imaging was weird, and a center image did not form during the time I spent in the room with the music I heard played. Notes kind of bounced around... I mean, the apparent distance between keys on a musicians keyboard is now, what, 3 feet? 6? Any small problems in setup and room acoustic seem like they would be magnified by just the tremendous size of the whole thing.

But the majesty of the setup is hard to communicate, the almost futuristic like presence of Technology with a capital 'T', or maybe it was more reminiscent of a cathedral, or perhaps it was the feeling of being present at what was at core a 'display fantastic', ...

 

 

 

 
Getting all 12 speakers up and running took awhile. Seems like they ran out of cables and amplifiers...

The Evolution Acoustic loudspeakers debuted at RMAF this year, as well as the new single box Emmlabs* CDSA CD / SACD player.

 

 

 

 
Yes, they are big in person, but they come apart in the obvious ways and can be purchased in three different configurations, depending on how much bass you might want, have room for, can afford. Listing for about $38K in this configuration, they sounded quite sophisticated during my short stay - as one might expect from a well-designed speaker with a ribbon tweeter and ceramic midrange drivers.

Kharma* Midi Exquisite loudspeakers with MBL electronics.

I thought this was the best sound at the show (ignoring our own rooms for sake of fairness). I heard some people say that they thought the MBL electronics was too cool sounding for this system - but I thought the characteristic musicality of the Midi's, and Kharma loudspeakers in general, showed through just fine - however I do not require much warmth to enjoy a system, very slightly to the warm side of neutral is where I like it.

Emotion, Enjoyability, Emotion, Naturalness, Emotion, with a lot of transparency which made it seem fairly Real, and the potential to be Impressive was also there, but for the severe bass nodes in the room which limited the bass somewhat unless one wanted to the bass to overwhelm the rest of the music - and I didn't.

These are the Midi's with the new bass drivers. Yes, the bass is tighter - but more important, from my perspective, is that some imaging / sound-staging anomalies that were present in the previous Midi are now gone. Just plain gone. No, it doesn't have the world renowned imaging / sound-staging / disappearing act of the Kharma 3.2 and Mini Exquisite 2-way speakers - but for a 3-way, which have much harder road to travel to get this right, the Midi is now world class. Combined with the Kharma 'sound', these speakers are perfect for those that want the Kharma sound, with lots of bass, in a larger-sized room.

Like us.

We have the Mini Exquisite speakers here at our showroom - and I know we should get the 3.2 next, or even the 3.1c, for the store but.... these would just kick butt in our second listening room... OK, Neli?

Another head-on shot of the MBL stack. MBL was present in quite a few rooms at the show - at least 4 that I can think of off the top of my head.

 

 

 

 
Another kind of money sink.

 

 

 

 
"For the Records" is a new store in our town of Boulder, CO, which I had never heard of before (on the Hill where Tulagi's used to be). LPs were $10 - $15, and in good shape, but I ran out of cash going through just one box here (they did not accept credit cards and I only had $100 bucks with me - I guess it is probably a good thing, too).

 

 

 

 
Kharma* 3.2 loudspeakers and MP-150 amplifiers, Kubala-Sosna cables, MBL front end.

We've heard this system a few times before. It is always very nice. But we hadn't seen the Kharma's in blue before, so before this is all over I'm afraid we are going to subject everyone to a lot of photos of the blue 3.2's.

 

 

 

 
 

 

 

 

 
 

 

 

 

 
Isn't it nice how the blue of the Kharma amp matches the blue of the speaker. How CUTE! as Neli would say.
