Amplifier Shootout – Audio Note vrs. Lamm vrs. Audio Aero vrs. Audio Note

We held a shootout here a few days ago – $85K Audio Note Ongaku versus $22K Lamm ML1.1 versus $10K Audio Aero Capitole versus $9K Audio Note Conquest Silver. Prices rounded, so don’t quote me to Neli :-).

The Audio Aero Prestige as serving as CD / SACD player, and sometimes as linestage as well. The Audio Note AN/E Signature loudspekaers were serving as… speakers.

So, with the disparity in pricing – it wasn’t really a shootout. More an investigation into different sounds – how the different amps sounded, given that they are indeed so very different from each other.


We finished up with the Audio Note Conquest Silver 300B amps.

We will try to describe the *differences* between the sounds, as opposed to the sounds themselves.

Going from the Audio Note U.K. Ongaku to the Lamm ML1.1.

The sound was not as big with the Lamm, somewhat more compressed – but perhaps more even-handed because the somewhat rolled-off deep bass [which lends the deep bass a compression-like signature], because of where the speakers were located [in front of the horns, which are out of here as soon as the snow melts. If it melts.].

The Lamm sound was more laid back, the soundstage receeding somewhat, which allows one to better appreciate the music in measured doses when desired, as opposed to being transfixed unable to move for whole CDs at a time [from this description I hope people see that we like both types of soundstaging – really depends on our mood at the time].

The Lamm harmonic color was a little grayer, and the dynamics, as mentioned above, a little less exuberant. This goes in keeping with our general interpretation of the Lamm sound as being stately and sophisticated, natural and self-consistant.

This is not to say that the Ongaku is an exuberant amp either – it is actually quite balanced, unexpectedly so from my point of view, with just a little flavor from the use of the 211 tube. We still have a lot to learn about Audio Note, but it is my current impression that as you move up in the Audio Note line, things become less colored and more accurate and therefore much more revealing of the color and subtleties of the music itself, quite unlike anything else out there. This seems different to me from the brands that, as you go up their line, you get more and more improved versions of their ‘house sound’. ‘Course, you can always tube roll the amp and get just about any sound you want – but I think the point has been made.

Going from the Lamm ML1.1 to the Audio Aero Captitole amp

The Capitole was sweet in comparison with the ML1.1. More euphonic, rounder, less resolution and transparency. For some reason, about half of the people we talk to these days are conscously steering away from high-resolution sound – so this amp, with ‘just enough’ resolution, should really be on everyone’s short list. No one really knows about it, but, especially teemed with the Capitole or Prestige CD player, you can get a really wonderful, Enjoyable and slightly Sweet, sound.

Going from the Audio Aero Capitole amp to the Audio Note Conquest Silver amps


The Audio Note Conquest Silver amps in play. The Audio Aero Capitole amp behind, resting.

Easiest to compare these to the Ongaku.

Less density. By which we mean less resolution, less micro-dynamics, less macro-dynamics, less color. Just less going on. But at the same time, note by note, it was the same: the notes were where they were supposed to be, the rose and fell like they are supposed to, they were just a little thinner sounding. OK, a lot thinner sounding.

Thinner sounding isn’t exactly ‘bad’, though, There is a lightness to the music, very similar to the experience of the $11K Kharma 3.1c versus the $45K Kharma Mini Exquisite, which I think is largely a psychological, not electro-mechanical, experience that is quite pleasant and refreshing. That sometimes a ‘lighter fare’ is as enjoyable, to a listener, as the full-featured experience.

Kind of like comparing the Simpsons [the old shows which had content] with a James Bond movie. One can enjoy both. But one generally prefers, and will actually pay more money for, the Bond movie.

Well, depends on the particular Bond movie 🙂

Interconnect Shootout: Nordost Valhalla Neutrix vrs. Valhalla WBT vrs. Audio Note Sogon vrs. Acrolink 7N-DA6100

The setup
The test consists of swapping out various interconnects between the outboard crossover of the Marten Coltrane Supreme loudspeakers and the Audio Kegon amps that handle the frequencies above 100Hz. Picutred you can see the gray Audio Note Sogon interconnect in place.

The Acrolinks

The Acrolink interconnect up close. These connectors are massive, and I believe this the only connector they come with. Very substantial and secure fitting things they are.

The Valhallas
These are the two Nordost Valhalla interconnects side by side.

Part of this test was for us to see… hear… the difference between these two connectors. Was it all just hype?

The Valhallas

The Valhallas with the new WBT connectors
We are not so sure about these connectors. They seem to pick up ground loops like nobody’s business. It is possible, and quite frequently the case, that:

* they are on too tight or too loose, in which case they either appear to be broken (aka no sound comes out) or

* they generate a large ground hum because they are not grounded at all (the area of contact on the target connecting post is dirty? or perhaps they are just too loose), or

* they pick up a small ground loop hum because they are only partially grounded (perhaps the connector is so thin that it needs its own shileding….?)

We love these old connectors. You put them on, they stay on. They feel secure. They don’t wear out after many, many uses.

The Shootout.

From one extreme to the other:

*** The Acrolink 7N-DA6100 – $4995 ***

Very clean. the cleanist sounding of this bunch (but not as clean as the Jorma Design Prime, at $2K more!). Very detailed and lovely air. Midrange is clean with perhaps a little too quick on the top of the note attack and on the decay. Bass is good.

*** The Nordost Valhalla with the WBT connectors – $4000 ***

Rounder than the Acrolink, more body. Also more veiled than the acrolink. Smoother because of it but there was also a whisp of a feeling of the music struggling to get out.

*** TheNordost Valhalla with the old Neutrix ***

The midrange frequencies are more laid back, a little more veiled. A little less midi- and micro dynamics in the midrange as well, compared with the WBT solution.

How subtle is the difference? In my mind I keep thinking 10% – whatever that means. I think it means that if the WBT was 100% better than it would be twice as good. In the midrange. In terms of these attributes.

In this test we did not get the dreaded ground loop hum with the WBT and we did prefer the WBT solution. The slight increase in resolution and slightly more presense in the midrange – was nice, and appreciated

*** The Audio Note Sogon – $2725 ***

The midrange was quite similar to the Vahalla in terms of detail and resolution, but with more color and subtle harmonic content. The bass was a little muddier than the other cables but a little more natural. The highs not as prestine as the Acrolink, and similar to the Valhalla in quantity but a little more natural in quality – i.e. not so much going for the ability to spotlight each detail in the treble, which I know many people like (including us, sometimes 🙂 ), but instead makes the details more integrated into the overall sound stream.

For this system, in its current state of break in (its making good progeess, finally) with the all Audio Note front end, we left the Sogon in place. It made the system much more musical to listen to, at least at this time.

There is a 5 meter Valhalla interconnect (Neutrix) between the linestage and the amps.

Swapping this out for, say, Sogon, or Acrolink even, would *probably* make the sounds of the various setups with these various cables more reflective of the underlying strengths and weakness of these cables.

[Is this always true? That a system cabled throughout with just one kind of cable will always highlight both the strengths and weaknesses of that cable? I know many manufacturers and dealers say you MUST use just their cable for your whole system to get best results. And I can agree with this if their cable is way better than what is currently in the system.

But what about using various cables as ‘spice’? I know that the word ‘tone control’ is a pejorative thse days, but until we get the perfect wire, all cables, including the lauded Belkin power cords, will be tone controls, like it or not. And so, taking this reality into account, I propose we must carefully, and consciously, spice our system with various cables lest we get something that tastes salty, …or like poop 😉 ]
