There are so many variables in delivering final system sound that when Great Sound is produced, it is inevitably a contribution of all the parts. Many times a single piece will be singled out for accolades. Conversely, when overall sound falls flat it could actually be one piece or
negative synergy of a speaker/room, amp/speaker, or amp/preamp pairing. It could be a speaker all by itself for a given listener or a source in the context of the rest of the system.
I literally cannot believe the changes in my overall sound tweaking the bass curves from 20 - 120 hz. I can dial in a warm and enveloping signature or one that is comparatively cool and clinical just within that range. This points to what I think is the single most important choice a listener can make - speakers. Some won't fit rooms. Some just won't have the desired characteristics in any room. A precious few fit the room AND all the user's parameters.
That's my long-winded disclaimer, and with that . . .
I had the PS Audio HCA-2, highly regarded. It was a cold fish, even with a tubed pre. It was matched to Gallo Ref. 3's which I really don't get. They do great special effects up high (I wish the tweeter was in a different speaker) but don't flesh the midrange nearly to my needs. Bass in my room was light but it was a really big room. I didn't care for the NuForce sound but that was an early 8 model and the new ones are probably better.
I've heard the Wilson Alexandrias twice, including the new V2 model recently with some very nice stuff. Even on vinyl these don't do it for me. They're cold, clinical, and comprised of many parts instead of a whole. I heard the W/P 8s too. I liked them better than the Alexandrias but still thought them unnaturally jumpy with indistinct bass. Interestingly, I thought they sounded superb on an unknown piece of classical music, it was when the going got familiar that I changed my mind.
In the same demo, I heard a Linn system that was
pentamped with all Linn stuff. Yep, 5 drivers per side with 5 stereo amps. The salesman said they sound way better this way. Whatever the theoretical advantage, it didn't play out. These three rooms were professionally set up with very good gear that should have been configured to show best sides of each piece, though tubes were notably absent from all.
I then heard the $35k Mac line arrays driven by huge Mac (1201's?) monos. Boring, man, what a sleeper. I can't imagine they're selling many of them, though they are really big and impressive. My buddy and I expected to get blown out of the room on dynamics so that one was a real surprise.
See, once you invoke the universal disclaimer you can fire all canons with impunity.
