Great multichannel amps do not cut it in stereo


This is more of a comment than a question.

I have been dabbling in hifi for almost two decades, and in the past 8 years or so moved into what I call 'quality' audio - as far as my budget could muster. I listen to multichannel all the time for TV and movies, but love my 2 channel set up, supported by my dedicated 2 channel amp to run stereo duties.

Since 2009 I had been lusting after the Arcam AVR600 as a no-compromise one box solution for both multichannel and stereo. With the AVR600 model coming to the end of its life I managed to land a new one for a very reasonable price compared to its original rrp. Heavy? Yes. Impressive? Yes.
However, as a two channel amplifier it did not come close to my $1500 Burson Audio integrated stereo amp in terms of detail, soundstage, PRAT etc - in my opinion.
As many have said before, you can not expect one car to be both a utility and a sports car; and you can not expect a jack-of-all-trades also be a master in one area. And this became very evident to me in my comparison.

The Arcam AVR600 is definitely a nice piece of kit, albeit it has its technical gremlins. But it simply can not keep up with a high quality dedicated stereo system, if that is what floats your boat. I can not imagine multichannel separates being much better, as these had been extensively compared to the AVR600, with most indicating a close to on-par performance.

So really, my message is that for high quality multichannel and great stereo reproduction, look for a two box solution including a dedicated stereo amplifier. Spend less on the former, and more on the latter!

Hmm, maybe that's why the 3 channel amp I had didn't cut it in my 2 channel system.
I doubt OP's contention would stand scrutiny as a general statement. What about 3 mono blocks packaged in a single case rather than 2 for stereo, e.g. some of the Levinson amps? I would guess there are multichannel amps that sound better for stereo than a $1500 Burson Audio integrated amp.

Yes that may be true ,ultimately, but multis are still better across the board than the amps in a receiver!
If I needed vastly improved home theater, doing stereo music duties, on the lite, im very ok with uper end midfi 3/5/6/7 ch amp n bettter AV processor running everything!
If however higher end 2ch music as priority is the setup, then im going two channel amp, dedicated 2 ch preamp, and I loop an AV receiver or prepro into that system, plus a multi ch amp possibly for the surrounds. Simple.
This is all of course considering an all in one location double duty system, as opposed to two separate systems, obviously. Pretty much that's it, I think.
Yup, mono amp s best, then stereo, then multi. Done
yea each monoblock must be connected to a separate dedicated power line. don't forget that.
As an instantiation of avgoround's suggestion, I use an analog Parasound JC 2 BP preamp with a pair of JC 1 mono blocks for stereo; for mch and HT I use a Bryston SP3 prepro, the front LR of which passes through the JC 2 BP to access the JC 1s while the SP3 goes directly to a third JC 1 for center channel and to a pair of A 23s for side and rear surrounds.
