Let me debunk most of the responses. I just bought a Crown K1 amplifier. It sounds as good, as ANY Krell, Audio Research, B&K, Adcom, Muse, Luxman, Hafler amps that I have owned. And it has power reserves in spades. I ran this amp fairly hard for almost 2 hours, and not one time did it ever even get warm. With 350 wpc into 8 ohms, and 550 wpc into 4 ohms, this thing never breaks a sweat. I have the K1 partnered with a Denon AVR 3805 as a 2 channel pre-amplifier. The highs are there, the mid range is there, and the bass is incredible. Transparency is very good. Highly recommended.
Can pro amps possibly sound good? Crown, QSC, etc
I have been looking into pro amps for a to-be-built HT/music room. Recently I came across an old review in The Stereo Times: The Complete Audiophile Magazine, which reviewed 2 discontinued Crown amps, the K2 and the Studio Reference I. The K2 the reviewer thought "not distinguished or especially musically refined", but the Studio Ref he thought an EXCELLENT full-range amp. It does have some amazing specs:
Signal-to-Noise (A-weighted) below rated full bandwidth power: 120 dB.
Damping Factor: >20,000 from 10 Hz to 400Hz.
780WPC into 8 ohms, 1160WPC into 4 ohms.
The review is here.
From what I've found so far, there are possbile downsides to using pro gear in an otherwise consumer setup, but in my case I think these are non-issues:
-fan noise: not an issue for me since I will have an equipment closet. Won't have to do a "fan mod".
-ugly: again, not an issue for me with an equipment closet
-hum: I believe not an issue as long as I use balanced interconnects from the prepro. Someone correct me if I'm wrong.
-expects pro-level input levels: I think not an issue if the amp has dip switches or gain controls?
And yet, over on a couple of AVS forum threads, I actually got asked to leave when I started suggesting pro amps. It seems as though some of the audiophiles there (and the same guys might be over here) don't even want to hear about a class of gear which imo just MIGHT sound good. It just isn't worth "polluting" an audiophile thread. Am I missing some other downside to pro amps, other than the above pints? Were these guys attitudes based on something substantive and audibly detectable, or just a form of audio bigotry?
I'm not saying all pro amps are going to be great (for instance I know the Behringer A500 is lousy), but might there be some good stuff too, like QSC DCA, or Crown Macro Reference (other suggestions would be welcome)?
