RE: Krazy kwestion about older Krell preamps...

Posted by AbeCollins on July 14, 2017 at 06:59:25:
"I'm willing to bet that SOME of these units have line stages that are VERY similar, or perhaps exactly the same as those found in Krell's stand alone line stages of the day (which still sell for a VERY pretty penny.)"
Possibly but I wouldn't count on it because most AV processors that I know of use multi-channel electronic volume control integrated circuits and signal processing to handle multiple channels simultaneously.
A simple 2-ch preamp can get by with a quality 2-gang analog volume pot or a less complex electronic attenuator (vs an AV processor). The volume control is a key element in how a preamp sounds and in my experience a 2-ch preamp will sound better than an AV processor for 2-ch duties.
If I were in the market for a Krell preamp on the cheap I would look to the KAV-280P. They're available in black or silver and to my ears they sound slightly better than the highly regarded (and older) Krell KRC-HR. But either of these may be available in your price range. I owned the KAV-280P for a while and it was very good.
