Don't forget that by some perverse coincidence many that are very keen on hirez also use tube amps wonder what happens around the ultrasonic resonance in the output transformer ? or in general with such a design that struggles a bit at normal hf ? especially with SACD a lot of "air and detail" if you are unlucky , maybe ? but again this is stuff nobody have tested either . I have always wondered in general if not many "exotic" designs used by many audiophiles have unforeseen technical limitations that no normal engineer expects that can explain why some things are audible that should not be ? -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
