Breaking in Sound Lab Ultimate loudspeakers and Audio Note M10 preamplifier together
Breaking in Sound Lab Ultimate loudspeakers and Audio Note M10 preamplifier together – using the EDGE Signature One amps and Audio Aero Capitole CD player driving them over on the floor to the right [Oh, you can’t see it in this picture, but you can see the Nordost Valhalla interconnects snaking across the floor there].

This is all just a temporary setup. We are breaking in each notch on the M10 volume control. We got up to ‘5’ yesterday, but that was driving the little Kegons pretty hard – and the Coltranes were getting pretty loud.

But over here, on the still somewhat inefficient Sound Lab speakers – with a solid state amp… we are doing ‘6’ today and will do notch ‘7’ tomorrow. That ‘should’ be enough, the Marten Coltrane Supremes (which made it through customs, yay!) are much more efficient than even the Coltranes, so notch ‘7’ should be plenty loud enough for the show…?

Every time we up the volume a notch, the M10 sound is bright and annoying for several hours and the pre lets off another waft of New Electronic Component Smell [Yummmmmm. Is this the only reason we buy TVs and computers and $50K preamps, to be able to experience this smell? Nahhhhhh].

This M10 + Sound Lab speaker-centered system sounds surprisingly good. The Sound Labs really like upstream equipment that errs on the warm side (as opposed to the more icey Parasound or Pass Labs soild-state amps, the former is usually shown witht eh SoundLabs at CES and the latter is to be at this RMAF show in the IsoMike room), and even warmish cables help – like the Pranawire Cosmos speaker cables.

The latest Sound Lab upgrade did seem to tighten the bass quite a bit and increase the midrange dynamics as well – adding perhaps 3dB? of efficiency. Still breaking in, but I noticed that the unfamiliar bluring of images in the soundstage that I heard when we first starting playing the SoundLabs after their upgrade has almost completely gone away.

The old Marten Coltrane system, going to pieces.
The old Marten Coltrane system, going to pieces Time to box up most of this system, and move the Marten Design Coltrane loudspeakers to listening room 3. The Sound Labs are going to go over here, next, after the show – and how we get around them when we go up and down the steps is still to be determined.

The current state of listening room 3
The current state of listening room 3. Most of the system proper is going to the show, including the Acoustic Dreams rack.

We want to put the Marten Coltranes in here after the show – but they sound best with the Lamm ML2.1 amps and the HRS MXR rack. But the Kharma Mini Exquisites sound best with the EDGE amps… it will be hard to build a system that is optimized for two different speakers like this… not to mention the Acoustic Zen Adagio speakers.

And then there is the HRS MXR equipment rack problem, or rather lack of problem: we want a double wide on the Coltrane Supreme speaker system in listening room #2,and another one upstairs so we can play a turntable in listening room #1 (it is the only thing that will work on our very bouncy floor) – but we currently only have one rack….

So little time (and money) and such a long Wish List.

Picture Medley

Just some fun pictures we had laying around on the hard disk…

Closeup of Marten Coltrane
Closeup of the diamond tweeter and ceramic midrange of the Marten Coltrane speaker. This is the walnut version of these speakers and the wood is starting to take on a nice rich patina as it ages.

Edge NL Reference
The Edge NL Reference 800 watt ‘pyramid’ amplifier. This picture really captures the sleek metalic look of the amplifiers.

Closeup of Edge NL Reference
Closeup of the top of the Edge NL Reference 800 watt ‘pyramid’ amplifier. Here you can almost see how nice it is to touch these amplifiers, the powder coating feeling very nice, almost soft, to the touch. The cap on top and the way the sides are fastened makes the amplifiers water tight (and maybe even dust tight, which would be nice… see below).

The EMM Labs Meitner DCC2 at dark
The EMM Labs Meitner DCC2 at dark on an HRS M3 Isolation Base. This picture captures the color-coding of the buttons nicely, as well as showing a how the volume knob is so much fun to turn by hand.

The Lyra Titan cartridge
The Lyra Titan cartridge on a Brinkmann tonearm. This picture does not show it perfectly, but there is this feeling of the loooong tonearm snaking out fron the depths at the back of the turntable, the head ready to strike with it diamond tooth into the platter.

Closeup of the Lyra Titan cartridge. Dust. There are lots of little dust particles, perhaps hairs from the wool carpet. They do not look serious enough toimpact the sound. But they are everywhere…

The Nordost Valhalla cables on the back of the Marten Coltrane loudspeakers. I like the reflections of the cables and binding posts in the shiny carbon fiber on back of the Coltrane.

The Nordost Valhalla cables in sunlight
The Nordost Valhalla cables in sunlight. I like the pattern of shdows the various layers of conductors make. When this picture is blown up large, this looks like a work of abstract art. Or maybe industrial art.

Closeup of the Nordost Valhalla cables in sunlight
Closeup of the Nordost Valhalla cables in sunlight held against the blue sky. You can really see how the cable is constructed. As desribed on the Nordost website:

“Each conductor is made from optimized diameter solid 99.999999% oxygen free copper that has 78 microns of extruded silver on the surface. The surface of each conductor is highly polished before a high precision Micro Mono-Filament wrap is applied.

The Micro Mono-Filament is helically wound over the conductor. A precision FEP jacket is then extruded over the conductor. A number of proprietary methods are used in this difficult and extremely precise manufacturing technique that reduces dielectric contact by a factor of more than 80%. Extremely mechanically stable, the conductors are effectively suspended in inert air, preventing oxidation. ”

Well, hope this all was as fun for you as it was for me!

PUTTING HRS 'FEET' UNDER THE EDGE REFERENCE AMPS

OK, we could / should really get some custom HRS (Harmonic Resolution Systems… now you know why everybody abbreviates their name :-)) amp stands for the big 220(!) lb EDGE NL Reference ‘pyramid’ amplifiers… But we got these really cool Rix Rax Outpost amp stands and we want to use them. The problem is the Outputs do not have all that much intrinsic vibration control (none except for spikes and the nearly 2 inch think maple tops).

What to do, what to do.

Kind of by accident, we tried putting HRS Nimbus Coupler’s underneath the Ref’s feet at the RMAF 2005 show – and lo and behold it helped even out the frequency response in the hotel room very nicely. In that situation the Ref’s were on the carpet because we did not bring down the big amp stands to the show – there is only so much room, you know, in a minivan and station wagon – when you’re full, your’re full.

So, the inspiration struck once more and we decided to try them again, only this time with the Nimbus Spacers too (we did not bring the Spacers with us to the show… why, because at the time we couldn’t find them.

OK, OK, everybody raise their hand who has so much audio… equipment and tweaks… that half the time they can’t find what they are looking for when they need it. Thought so.

HRS Nimbus
Here we see two Nimbus Coupler’s and one (double height) Nimbus Spacer

Here they are in context to a standard (good) CD.

Here is the big EDGE amp

Here is a Nimbus (Spacer plus two Couplers) under one of the feet. No it isn’t exactly centered. You want to liff this 220lb thing to try to get that last 1/32 of an inch? Not me either.

HRS Nimbus
Here is another picture of the HRS Nimbus’es under the feet. Notice the dust under the amp that the added height now reveals. Everyone knows half the fun of having all this beautiful equipment is dusting and keeping it clean, right? Right?

Hurrumph. And it is not as if we can trust anyone else to clean it either. What a predicament. What a predicament.

Next … the Effect of Dust Bunnies on Soundstaging….

Oh, and the sound here with the Nimbus’ under the EDGE NL Reference feet is the same we experienced at the show – a more even treatment of the frequency spectrum, removing some of the edge and glare we were experiencing with bad recordings, especially DVD video.
