Wherein we go into more detail about the sound at this year’s CES.

First, Robert Lee of Acoustic Zen knows how to set up a room at a show. He knows what kind of sound he is after, and if the amp he was supplied is not doing what he wants, he will put it on static display and use something else that gets the job done.

What this means is that 1) you can go to their room at a show and be pretty certain it is not going to suck. In fact, it will likely be quite good sounding [we’ll go into what good sounding means in this context below], and 2) that the amps he is using are amps YOU can use with these Acoustic Zen speakers and be pretty sure that it is going to also sound good.

Yes, this is indeed extremely rare. By far most rooms (99% or so), even ones we give best of shows to, either A) sound good because they got lucky and the unfamiliar amp from a manufacturer who was the first to agree to share costs of the room JUST HAPPENED to sound good with the speaker manufacturer who was the first to agree to pay some of the room costs or B), the quality of one of the components, or the speakers, is so good that even with mismatched components the room still sounds pretty good.

Acoustic Zen has paired with Red Dragon, Edge, Response Audio and Tri.

Essentially, the Crescendo speakers are full-range Adagio speakers, which were already pretty full-range but were not enough for people with larger rooms or who listen to a lot of classical music and want the lower octaves to sound realistic. The Crescendo has a greater ease of presentation and a bigger, fuller sound.

Which I think is the point of these speakers.

First, most speakers in this price range suck. They are a joke. Few attempt to do full range and those that do usually suck more.

Let’s talk about the ones that do not suck for a minute.

We have the Marten Miles III and Kharma 3.1C. More detail, more transparency, more audiophile, but no where near the authority or frequency range.

The Soundlab A1 has the frequency range, but not the authority unless you really out a mofo amp on it, but if you want a electrostatic then you are probably not reading this post anyway.

You got the Wilson Sophia [not the range or sense of ease], Avalon… not sure which one [not the authority or range], Audio Note [if you have corners available. If you do then this might be a possibility, with careful attention to setup]. Let’s see… what else?

Most people who come here to demo these speakers, to tell you the truth, have just come from auditioning the B&W, Definition, and JM Lab/Focal. They have just been fed tipped up midrange hell and musical slurry. They are rarely audiophiles and we have so little time to demonstrate to them that they are on the road to ‘audio hell’ [when they see $350K speakers, they think we have already arrived at audio nutsville :-)]. The Acoustic Zen are audiophile-grade speakers, whereas the others are not [sorry]. Which takes us to the next section.

These speakers have what I think of as 2 distinct sounds – depending on the amp driving them. With a Red Dragon amp, or little Kharma amp, these are very dynamic, fairly quick sounding speakers. With Edge amps and tube amps, these are more…tube-like, a little more harmonic and continuous. With BAT amps you can achieve the middle ground – more or less.

We’ve found people greatly prefer either one or the other with these speakers [whereas we do not. We like both flavors of sound].

I think these speakers are for music lovers, not quite so much into the sophisticated sound gymnastics as some audiophiles are [guilty as charged, love those crazy subtle details and intricacies!] , and want a audiophile-grade full-range speaker for an audiophile-grade 2-way speaker price.
