The Raidho D-1 Monitors were stunning on their custom stands. (The integrated speaker package has an MSRP of $28,000.) It was quite surprising how they are able to fill the room. For a smallish profile, they were amazingly full range and dynamic. This was another room with Merrill Audio amplification.This just means that they filled the room and sounded dynamic. Plenty of other stand mounted speakers can do that. You can check many other reports on these rooms and you'll find that they either just mentioned the gear in the room or used generic terms to describe the sound.
On the other hand, a lot of audio gear can produce a very clean, taught, fast, controlled, articulate, high contrast sound. But this doesn't necessarily mean that it sounds real. If one listens to a lot of live music, it then becomes more difficult for the brain to associate reproduced sound with live music. What I heard from all three rooms was a sound that was going the opposite direction of trying to reproduce a live performance. I can extrapolate and say that all three systems will certainly sound better in a more controlled environment, but I'm not that optimistic and think they'll sound like live music.
Designing amps can be very, very difficult. It took John Ulrick from Spectron a few decades to produce their excellent live-sounding amps. There are a couple of other legacy companies that also took a few decades of research and customer feedback to arrive at the great products they produce today. Many of these engineers happen to also be musicians. Their products simply aim at recreating a live performance in your room and that, IMO, should be the ultimate goal. An engineer can produce the most desirable measurements from an amp and not sound real at all. On the other end, some high-distortion tube gear can sound so real.
Now, let's not confuse noise with distortion. I've heard a lot of high-distortion tube gear that sounded very pleasing and real. I have not heard a system with some electrical noise in the signal sound pleasing and real.
Musical instruments have all kinds of sound. My wife and I went on a cello auditioning tour a while back. We encountered cellos with fat lower frequencies and clean upper frequencies, cellos that were very quick to recover from excess reverberance, cellos that sounded lean and forward, but the one thing that they all had in common is that they sounded real. And this is the experience I want to dive in at home when listening to music.
