If you are going to purchase a Krell and price is a concern and even if price is not, purchase a KAV 2250. It has 250 watts p/Ch and and it is one of their newer and in my opinion one of thier better sounding amps. Because it is newer it is going to be more reliable and probably not in need of replacing the caps for yerars to come. I have owned many Krell amps over the years and this is one of my favorites. It is a very simple straight forward design (something that is unusual for Krell). It has a very transparrent and yet has a powerful sound. I have owned a KSA 80B, KMA160 monoblocks (USED & ReCapped),KSA 200s (USED Recapped), KSA 250(Used recapped), KRS 100 Ref Mono blocks (USED), an FPB 600 stereo amp(New), KAV2250 (Used from a friend)I have sold all my Krell but the 2250 is my favorite Krell amp, it is musical & powerful and it just sounds awesome and used for $2400.00 you cannot find a better deal. I now have PASS LABS but like the KAV 2250 over all the other Krell amps I have owned. Simple is best and it sounds better too!
