What s wrong with Krell HTS?


I'm looking to buy an A/V preamp for music and HT and I noticed lots of used Home Theater Standard's for sale at attractive discounts. Is there something wrong with this unit? Is ths Proceed AVP better, easier to set up, etc.?

Incidently, Irv Gross of Krell's Sales and Marketing Dpt., sent me a recent email stating their official policy on warranties on used equipment sales. All warranties on products mfg after 1-1-2000 would flow to subsequent owners if original purchase was made from a licensed Krell dealer and copy of original sales invoice accompanies the sale to the new owner as proof. Some Krell dealers have been stating that only used Krell products purchased from a Krell licensed dealer would maintain original warranty. This is misleading statement and not Krell's warranty statement. I would be happy to forward a copy of this recent email to anyone requesting it.
The old KAV stuff sounds great, they are still currently the best sounding amps in their price range. The comments by Sabertouch are true. There are few differences between the 2 HTS's. As far as the software issue, call Krell and get the latest Eprom. It's free and all of the bugs have been addressed. Both my old HTS and new one had the same software eeprom and both work glitch free.
Not impressed with krell sound, but to each there own. The older krell is nice. The new kav stuff really sounds sterile. I think you can do better for less. IMHO
