Old Krell vs new Krell amps...


Hello,
I actually have to choose between differents Krell amps, for roughly the same price :
a pair of Krell Audio Standard (KAS)
a Krell Evo 302
and for half the price a pair of KAS-2 amps

How do they compare, in terms of sound ?
The KAS is a legend, but is it actually still a good choice ? Its fiability is good ? The KAS is really better than the KAS-2 ?
And, what about the new Evo amps ? Are they better than the KAS or the FPB amps ?
My speakers are easy to drive : Tannoy GRF, but I may swap to big TAD or JBL...
I can't compare those amps directly because they are sold in different(and very far from each others) shops.
Thanks a lot for all informations and advices.
Best Regards,

And we are forgetting the Krell Reference krs 200 monoblocks (a pair just showed-up at Audiogon today) - some people consider it one of the best amplifiers ever manufactured.
SME founder Alastair Robertson-Aikman used a pair in in famous listening room, and as far as I know they are still being used to drive his modified ESL63.
Hello,
I've seen the KRS-200 on audiogon : very tempting too...
But I don't understand why the seller has to change the XLR inputs...

Usblues : you think that my actual GamuT amp is better than Krell amps ?
The KRS-200 are 20 years old...
Should I be concerned with reliability problems with those kind of amps ?
Well,its a fine amp and in the right place[synergy] could easily equal/surpasse the Krell offerings which are also fine depending.....Krell amps and Tannoy speakers?I don't quite get the reason for change.That speaker doesn't require lots of current.It seems on paper a single Mosfet/channel would be ideal.Am I missing something?Thats ALWAYS possible....Bob
Early Krell balanced amps used a pair of RCAs for the balanced inputs thus the XLR input change I suppose. The KRS amps are impressive but do use a lot of power and will probably require some service in the near future. Also, they are very heavy and shipping will be expensive when service is needed.
