@ Rcprince, Hi, That is odd that you have that opinion, My opinion is my New rebuilt, Everything 2014 as opposed to what was available in 2005 new inside and out Krell 700cx has a way better sound than the Krell FPB 200 I had many years ago.
More Tubes = Better Sound
I am wondering if anyone has thoughts on the sound quality of using more tubes to get the same power as an amp that uses less tubes? I had a pair of VTL MB 750 and they had 12 tubes for the output. I am looking at an ARC ref 600, however, it is 250 watts less and uses almost 3 times as many tubes as the VTL MB 750's. does anyone know the logic here? I am thinking of passing up on the 609's due to the expense if the tubes, but is there an advantage to using so many tubes?
