Teck, from Singapore, played a female vocals CD in our room, and likely a few lucky other rooms as well, at RMAF, and kindly and generously sent us a copy of it:

And, uh, it is surprisingly difficult to render well. The second track, specially, the singer has lotssssssss of sssssss’s in her ssssssinging that can caussssssse ssssssibliance when played back [i.e. sharp S sounds instead of delicate, sweet s sounds]. Luckily, the completely optimized system we took to the show played everything perfect, but some of our experimental systems, that otherwise play flawlessly [more or less] have difficulty here, and truth to tell, the playback in general on this CD could be better.

I think the answer will turn out to be a combination of the fact that we are playing it LOUD [what? L-O-U-D!!! Anybody else have these strange conversations when the music is loud? That usually end in “Forget it. I’ll Tell!… You!… Later!…”. “WHAAAAT!?”], the equipment is sitting very nearly right in front of the speakers, and the bass needs adjusting because the room is so large - we got used to using an integrated, and I do not think we have used solid-state on the main towers for over a year.

So we struggle, changing power cords, cleaning the CD, changing cables etc. to try and figure out what thing[s] are responsible. Everything to avoid having to move things or put a rack between the speakers [on the other hand, Neli is happy as a clam to have Mike move things, including racks, to and fro, fro and to].

System 1

Lamm L2 linestage’s power supply

Lamm L2 linestage. Just about everything is on HRS M3 Isolation Bases.

Emm Labs CDSA CD / SACD Player.

Anyway, that is what’s happening here. The Vidar has not yet arrived so we are not burning in anything that needs to be burned in. So, we are circling the field waiting to land.

System 2

Audio Note Ongaku integrated amplifier

Audio Note DAC 4.1x Balanced

Audio Note CDT Three transport

And, yes, Teck, your other CD arrived to [Thanks SO much!]. But, uh, I accidentally left it in the Emm Labs CDSD SE which, uh, is unplugged and at the moment away from an outlet, and I need to find a power cord for it somewhere [can I use a stock $2 Belden power cord? Of Course Not ] and plug it back in so I can eject the CD [See, I TOLD you all that I do this ALL THE TIME. Don’t know what it is… some kind of curse because I ‘let’ Neli clean all the CDs (and records, too) or something… ]

We like the CDs. We are certainly playing them a lot. The soundtrack is a little like the Gladiator soundtrack… I mean, doesn’t it seem like soundtracks have their own genre -they’re not classical and they’re not pop. Cool depth of field though, and amazing drums.

As you can sort of see, we have the Emm Labs CDSA player going into the Lamm L2 (Lamm L2 power supply is on left, L2 linestage in center), and from there into the Marten active corssover and into the Edge Signature One amps.

This is a pretty good sound. We haven’t heard it enough to really understand it yet (busy here on the phones, etc.). One thing is obvious, these speakers will love as much as you can give them: resolution, micro-dynamics, harmonics, …

We Are Unworthy! [anybody else like Wayne’s World? Anybody? Bueller?]

OK, downstairs we have the Audio Note CDT3 transport into the Audio Note DAC 4.1x Balanced DAC into the Audio Note Ongaku integrated amplifier into the Kharma Mini Exquisites.

The cables here are interesting: we have regular Valhalla RCA interconnect for the digital cable, Audio Note SOTTO interconnect and Jorma Design No. 1 speaker cable. The SOTTO only has about 12 hours on it [but our Nordost Vidar cable burner should be back soon from the factory - it was happily burning cables in when the lightning struck].

The midrange makes me want to cry. It is so involving. [Now THAT is something I am too much of a boy to say out loud, but I feel I can say it in writing. Alan Alda may have made it OKAY for men to cry - remember that anyone? Bueller? - but just about important things. Not about how beautiful music can be. That, that, if someone comes into the room, I have to kind of look away and think about the economy or something. Tears dry right up. Though the economy is getting to the point where I might start crying harder… $1.46 per Euro]

Been moving things around some.

We are trying to setup things so that we have two systems we can wire with all Nordost ODIN cables [hopefully here next week], with 2 interconnects and one speaker cable [we are ignoring the Coltrane Surpreme’s bass tower speaker cables, at our own ear’s risk, of course - but our pocketbooks and wallets thank us].

Edge Signature One solid-state amps driven directly by Audio Aero Prestige, with Brinkmann Balance turntable and Lamm LP2 phono plugged in to one of the inputs on the Prestige.

Unfortunately, the limitations of the $14K Prestige’s built-in preamp [linestage] is evident, things being a little muddier than what we are looking for [especially in comparison to the pre in the $85K Audio Note Ongaku we were using before ]. The Prestige’s built-in pre is fine for things up to, say, $40-50K speakers, at which point the decision on whether to get an outboard preamp has to be made on a speaker by speaker basis - and the size of one’s wallet. The Kharma Mini Exquisites like a little more oomph of the extra pre, the Marten Coltrane speakers do well with either.

I’m sure the Audio Note M10 linestage on the Kegons would be great, as well as the Lamm L2 linestage on their ML2.1 amps, but then we are talking about 3 interconnects for digital instead of 2, and so no 100% ODIN setup.

Downstairs, we have the Emm Labs CDSA driving the Lamm L2 linestage into the Audio Note Kegon amplifiers. Interesting mix of brands, I know, but it sounds re-e-e-e-al good - and it allows us to swap in different amps for demos.

But, since that demo has been postponed, and in the interest of limiting this system to just 2 interconnects as well, we will setup the Emm Labs CDSA player [and/or Audio Note CDT3 transport and 4.1x Balanced DAC] connected to the Audio Note Ongaku integrated into the Kharma Mini Exquisite loudspeakers.

If we just had ONE more pair of ODIN interconnects… and another speaker cable for the bass towers on the Supremes [probably open up their bass something wonderful], … but, no, we can’t go there. That way lies madness.

A final shot of the Audio Note amps.

We hope to have an 100% Audio Note Sogon cabled system - with some of their SOTTO thrown in as well before too long. I anticipate completely different sounds from these systems using these different cables And we already did the 100% Jorma Design Prime system [at the RMAF show].

It will be so much fun hearing all the differences.

This is what life is all about: enjoying the differences this world has to offer, and experiencing the fruits of expert craftspeople in the pursuit of excellence.

[… previously on Audio Federation…]

[… as we return to our story…]

:-)

The Kharma Mini Exquisite speakers [the Lamm ML2.1 amps are out on audition]. At reasonable volumes, this combo is SO seductive.

Sometime we should all have a sit down and talk about what is a reasonable volume. This is probably the area of most divergence among audiophiles, by which I mean some people like it always around 80 - 85 dB and some like it always around 110 dB, and lots like it in between these SPLs. This is a WIDE range, and a system optimized for one level may not necessarily do so great at the other extreme.

The equipment driving the Lamm ML2.1s [The Walker has been moved so that work can be done on the light switches that melted during the lightning strike]

The room from the Kharma’s eye view. Those are the soundlabs in the back there and the red leather command chair in the front.

The equipment driving the Ultimate Soundlabs. Neli set up three digital on this systems: Audio Note, Emm Labs, and Audio Aero for people who want to do a digital player taste test. It is somewhat compromised, everything running through the Audio Aero Capitole CD Player’s built-in preamp, but it does help people understand the CHARACTER of the different player’s sounds.

And the main system upstairs. Still not positioned 100%, as Neli annoyingly reminds me. We just need to play a few dozen records and start the speaker positioning rumba: play, listen, move, listen, move, play something else, repeat.

The 3rd listening room is still a mess: Adagios, our RMAF Audio Note system and rack, trade-in Nolas, DeHavilans, cables galore,…. it is a very expensive Mess.

[Yes, still working on the show report. Taking a break here tho…whew!]

We setup the show system back in our living room with a few changes:

* Using a 2 meter Valhalla instead of a 1.5 meter Jorma Prime interconnect which we had borrowed for the show (thanks Dan!).
* Putting the bass towers inside of the main towers.

We wanted a wider soundstage than what we were getting here, in our room which is narrower than the room at the show. As long as we keep the bass towers back far enough, and close enough to the main towers, it shouldn’t mess up the imaging… much. And it doesn’t, at least with the 1/2 hour of modest volume testing we have had time to do so far. Did make the soundstage quite a bit wider

And, no, before anyone asks, the vacuum cleaner is NOT a secret tweak of ours. Really. It’s not.

We also have, finally!, got the MXR rack and Brinkmann Balance turntable upstairs in the main listening room. Looks awesome there. Seems to sound pretty good too, but, like we said above, we have only just started optimizing this setup.

Another photo of the system.

Took us long enough, huh?

Well, we had an excuse, with the huge horn speakers hogging all the space up until May.

Then Neli’s sorry excuse for a husband was under orders not to lift anything heavier than 25 - 35 lbs. for 6 weeks - which we determined actually did rule out 300 lb bass towers.

And then we had audition after audition - and everyone really loved the Audio Note Ongaku on the Kharma Mini Exquisites with the Jorma Prime cable. - so we were hesitant messing with perfecttion [but this system will be downstairs, so we’ll see how much the size of the room contributed to the sound - it IS a small system, after all]

We had some concern - and numerous, numerous, numerous to the point of ridiculousness - discussions about how to get the speakers up to the main room. How to wrap them, ho wmany layers, how dirty the blankets could be, using a hand-truck, going outside instead of up the stairs, I was about to die with all this talking - what is WRONG with me that I was the one who started the conversation half the time?

Here is the stairs we carried them up. Neli did great carrying the top of the speaker up, and we did take off the 40lb or so spiked feet - but otherwise we ‘just did it’, like Nike keeps telling us to do, though at least with the second bass tower, we wrapped the banister with towels to prevent any ‘accidents’ - which luckily we didn'’t have (whew! and yippee!).

We put the EDGE Reference amps on the main towers (800 watts on top, and the built in 2000 watts on the bottom - these boys go LOUD - so far I haven’t turned it up above -32 on the Capitole CD player - which is already over 100dB). Well, we wanted to wake up the speakers and this should do it.

Positioning still sucks.

And now starts the long journey to finding the magical combo of components that will make these speakers sing the way we know they can. This currently ain’t it, not the least reason of which is that the Capitole player needs vibration control bad - there is some serious BASS going on and it is just sitting on the Black Diamond Racing cones, right there next to the speakers, poor thing.

First off, daughter got successfully married to her first husband (hey, one can’t ignore statistics - or heredity , relatives have come and gone, and time to get back to work….

I’m writing this in Firefox, which has a built in spell checker, so if all goes well my posts will read a little more like English and less like Mikeish.

So… the ro0ms are pretty much the same as they have been…

We have the Kharma Mini Exquisites upstairs waiting to be tried with the Audio Note Ongaku, Driven by the Emm Labs CDSD/DCC2 (the CDSA is out on audition - for those that want transparency and musical truth, this is an amazing deal at $10K, the bar has been raised significantly).

The Mini’s are somewhat hard to drive, so we’ll see if the 25 watt Ongakus do it or not.

The dream system - Marten Coltranes driven by Audio Note Kegon amps and the Audio Note M10 preamp (with an Audio Note digital front end - CDT3 and DAC 4.1x Balanced). We’ve taken most of this system to Rocky Mountain Audio Fest shows - but not with the M10, which adds C-O-N-T-R-O-L. Kind of a Kegon++ type sound. A slightly rounder sound than the Lamm ML2/L2/Coltrane/HRS system/Jorma Prime - our other reference Coltrane system - we might take the former system to CES next year.

The equipment rack. Duh.

The Marten Supremes need to go upstairs - yes - at 300lbs for the bass units (includes the 50lb spikes on the bottom) Neli is pressuring Mike to get the to a gym…. but we might just hire some guys we know - who handled the Triolons several times and will be happy to see that these are REASONABLY-sized speakers for a change.

Finally, out smaller system room. The Audio Aero Prestige CD/SACD player into the Audio Note Otto integrated into Audio Note speakers. Very nice and immediate and uncompressed. Otto still breaking in though….

The closeup view…

The main listening room is the same as last week, with the Audio Note Ongaku driving the Audio Note AN/E SEC Signature speakers, but with the Emm Labs CDSD / DCC2 SE digital as source replacing the Audio Aero Prestige, which has moved downstairs…

This room did experience a major amp shootout, more in the next post about that…

The showroom #4 is also the same, with the Kharma MP150 amps driving the Audio Note speakers, which at 98 dB are very eifficient… with the Audio Aero Capitole CD player / linestage as source, this system sounds really good. I’d like to hear any other digital amp, or most solid-state amps for that matter, do that.

Showroom 2 has seen lots of changes…

First we had the Emm Labs CD / SACD player with built-in linestage driving the Audio Note Kegons into the Kharma Mini Exquisite loudspeakers. THAT was nice…

The we moved the Meitner upstaitrs on to the Ongaku (can you say transparency? separation? purity albeit not as warm and enaging as the Audio Aero Prestige, but more convincing. So many flavors.) and did the front end with the Audio Note DAC 4.1x Balanced and CDT3 transport and M10 preamplifier.

Much more control and control and, uh, control. Everything was as it was supposed to be. Unfortunately, the 18 watt Kegons have found their first speaker that they just could not get the hang of - at loud volumes - and we’ve driven just about everything here with the Kegons except the soundlabs. The 18 watt Lamm ML2.1 also has problems with controlling the Kharma speakers at loud volumes. Based on what we have found, they really sound best, if you want them to go loud, with the Edge Signature One and Kharma’s own amps (the MP 150) if you want transparency and openness and control, and the Lamm ML1.1, a 90 watt push-pull tube amplifier, if you want tube musicality and openness and control.

We have yet to try the all powerful Ongaku at 25 watts on these though…. Maybe tomorrow?

For showroom 3, which is in the same room as showroom 2, we have…

The Soundlabs taking a break, but not the Marten Design Coltrane speakers, Lamm L2 preamp, LP2 phono stage and Brinkmann turntable / Titan cartridge. Audio Aero Prestige is performing digital source duties.

This is one of our favorite systems. However…

We had to position the Coltranes in front of the Soundlab U1. Impromtu but it seems to work pretty well. I mean, needs lots of trweaking - but we think it will work! The Coltranes like being close to the front wall, and the Soundlabs are kind of a wall…

Now Neli wants to move the Supremes over here on this side of the room [and in front of the Soundlabs!?] , as the dedicated circuits on the other side seem like they are picking up FM radio, secret transmissions from Mars, and other weirdness on several different systems that have lived down at that side of the room.

I now think it is ghosts.

But Neli, if her expression is any indicator, thinks otherwise.

… have seen us iterate through a lot of different systems…

Main room with Acoustic Zen Adagio and Audio Note AN-E SEC Signature speakers and Ongaku amplifier, driven by Audio Aero Capitole

Listening room 2 with Marten Coltrane Supreme loudspeakers driven by Audio Note Ongaku amplifier and EmmLabs digital front end.

A close up of the components. This is the whole system, these 4 components. Nice and tidy for a change…

However, though this system reached a level of musicality and approached the sound that we are looking for this system have - it was too bizarre having two preamps in the loop, the preamp in the Ongaku serving to try and match the SPLs of the midrange to that of the bass amplifiers. It worked, but…. We might try this again - but for now….

… we changed this, we now have the Lamm ML1.1 push-pull amplifers on the Supremes.

… which will chaneg for an audition tomorrow, assuming they can get up the driveway and up the stairs - which is not a given anymore with this Monther of all Winters the world has on its hands.

Back upstairs again, after the unphotograhed step with the Acoustic Zen Adagios being driven by the Audio Aero Capitole amplifier…

We got the Audio Note Ongaku amplifier driving the Audio Note AN-E SEC Signature speakers, with the Audio Aero Prestige as front end this time. We spread the speakers wider apart also, to see just how wide a soundstage we could get and possibly get some reinforcement from the nearby wall and horns

But in either position, the Audio Note speakers filled the room nicely. The midrange even approached the capability of the big horns to fill the room, and the bass - once the horns are gone we can try to position the little guys much closer to the wall - the bass is decent and satisfying but does not match the 4 x 10 inch woofers in a sealed cabinet… yet.

In fact, we will likely have 3 kinds of bass in this room: the big relaxed bass of the horns [no we will not mention their brand name - they can do their own marketing for a change], the ultra accurate and ultra powerful bass of the Marten Coltrane Supremes, and the very natural sounding, horn-like bass of the Audio Notes. How cool is that!!!

We’re going to have to post sometime about how it is not about what is ‘best’, but about is most ‘insidious’, and particulary, the number of ways it can be configured to be ‘insidious’. Insidious in that it produces a sound that gets into your head and just takes over.

The Audio Note U.K. Kegons amplifiers are on the Kharma Mini Exquisites, with the Lamm L2 preamplifier and Audio Note digital front end (and Audio Aero Capitole as well, in shootout formation). We then put the Kegons on top of HRS platforms, which is how it sits tonight.

Tomorrow we may get a chance to put the Mini Exquisite speakers over on the Supreme system in an all Audio Note configuration - with the Kegons to start, and Ongaku later if our snow shoveling arms hold out.

Finally, we have the system in listening room 3, area #4, with the little Audio Note speakers with the Kharma MP150 amps driving them, the Audio Aero Capitole serving as CD player and preamp.

Kind of a hodge podge system as we are in the process of breaking in the speakers - but it sounds darn good….! Neli likes it and her office is across the way. These are high-efficiency speakers and they reveal that the 1st watt of the Kharma amps is really quite good sounding, regardless of it being solid-state, digital in fact.

Everything is currently unplugged, of course, in response to last nights storm and the storm expected tonight…

But there have been a few changes in the last few weeks…
