[rec.audio.high-end] amplifier recommendation

dxt@hyperion.haystack.edu (David Tetenbaum) (08/11/90)

I want to replace my 20 year old AR amp with something more modern
and powerful. The speakers are KEF 101's. My budget is about $400.
I'm considering a used Apt preamp with a to-be-determined amplifier,
also used. Does anyone have any experience and/or comments about the
Apt amplifier vs. a NAD unit? How does a 40 w/c amp with "power envelope"
stack up against a true 100 w/c amp?

NAD power amps have always been partly modeled on the concepts (some
of them) in the Apt design (good current delivery into difficult and/
or low-impedance loads). A working Apt at a good price that
is not too hissy should do you fine; a high-power NAD will go louder,
briefly, and a lower-power one will not. By power I mean that what matters in
audio in the home (depending on your speakers) is how much power a
given design can put out for a half-second, say, into the load it will
be driving. The only way to check this is to do it, alas. I do not think
you will go wrong with either choice. A newish NAD might be marginally
quieter than the Apt, which is by now probably a decade old....

I personally recommend ADCOM power amps.

The capacitance of ADCOM amps far surpass any others. Just try lifting one
up. Lifting a 200w ADCOM will give you a hernia.

The best example is to take an Adcom and turn it off while music is
playing; the sound will continue with no lessening in quality for no less
than 30 seconds...

and best of all, they're CHEAP (and, some can support _2_ pairs of
speakers)

Brystons Amps are also excellent.  In fact they are now taking over Carver
as the choice amp for professional applications.  The reason:  they are quiet,
clean, powerful, and high current.  Yes!  You can turn off a Bryston and 
listen to it for atleast 30 seconds too!!  Lifting up a Bryston is not 
recommended unless you want to pump muscles.  All Brystons amps support 2 pairs
of speakers.  Bryston offers the following:

	2Bryston	50w/ch [200w bridged mono] (8 ohms)	~$1000 ($CAN)
	3Bryston	100w/ch [400w bridged mono] (8 ohms)	~$1700 ($CAN)
	4Bryston	250w/ch [800w bridged mono] (8 ohms)	~$2200 ($CAN)
	6Bryston	800w [mono block amplifier] (8 ohms)	~$2200 ($CAN)

Take your pick!  Both ADCOM and Brystons are excellent reasonably priced 
amplifiers.
