Audiolabyrinth,
I have always been enamored of Krell amps. The Krell products I have owned in the past are the junior integrated amps, the 300i and its progeny the 400. The reason why I never upgraded to the bigger amps is that they are pure Class A, which means putting out a lot of heat and at the same time emptying my wallet for the monthly electricity bill even at idle, which could otherwise go towards buying more music.
I have not heard the Cipher but the Evo model before it sounded gorgeous in the showroom. The Stereophile review of the Cipher awarded it Class A as you already know.
You can just get the Cipher with the stock Krell CAST cables. The CAST connection with a used Krell KCT preamp(also very well received by the pros) may just be the ticket to audio nirvana. Well, it's either that or sonic hell but I very much doubt it could ever be the latter.
Cheers!
