Dadio,
I would not take a KAV over a KSA any day of the week. I'm not saying the KAV 250A is bad, it surely has the power ratings, BUT the KSA-80b has musicality in spades all over the KAV series.....KAV stands for Krell Audio Video and this seems to be where it is best suited. KSA aka Krell Stereo Amplifier is where the music begins.
I had nothing but older Krell amps at one point, starting with the KSA-100, KSA-80, KMA-160's(mono version of the KSA-80's), KSA-150 & 250, MDA-300's & 500's. I borrowed my dealers KAV-250a for 2 weeks for comparison with the KSA series on hand. Not even in the same league! It would get "in my face" no matter what I listened to. A BIG IF is your speakers? Not knowing what you have is tough to say what will happen. In my honest opinion I truly believe the KSA-80b to be a much better build quality, sound quality and more relaxed sounding amp. Don't let the 80 watt rating fool you....it doubles in power as the ohms are halved and has as much current as some MIG welders. The KAV's do not have this ability.
The easiest way I can describe what happened in my system goes like this: While driving Thiel CS-3.6's which are ruthless of upstream components the KSA-80b filled my large basement/apartment with full rich sound. Switched to the KAV-250a and my Thiels did nothing but "scream at me" unless played at low volumes. KAV always sounded strained no matter what cables I used.
I hope that helped?
