Boisehomes, I tried an LS26 with my Krell FPB400cx, running 10T's. It replaced a VTL tube pre at the bottom of the VTL line. It was very disappointing. The mid's were very nice, but the deep low end that 10T's are capable of disappeared. Really anemic. I sold it and got a Krell KCT. The bottom end came back in spades, and it's really smooth, though I'll admit I lost some midrange magic. I'm thinking that a Ref5 might do the trick to get both, but that budget's a little ways off.
