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,

I own 2 of the Kas-2 (purchased used 5 years ago). One of them went up in smoke, and I am reluctant to send them back to Krell. They told me (judging from the picture: top of circuit board burned badly), they do not have the replacement circuit board anymore, they can't fix it. I live in California, shipping would be very costly. Now that I hear about yours going up in smoke, I am scared to spend money on them. I love the sound, but Krell is not accommodating me at the least. Can you give me an idea? Attila
Did you ever get your amp fixed and if so by whom? Did Krell ever offer any support? Do you like the amps?
