Parasound JC-1 vs. Pass 250.5

I cannot compare the 250 and the 250.5, but I have owned both the 350 and 350.5 and indeed there is a big difference. The 350.5 is warm and quite tube like. It is never fatiguing and still getting better as it now has about 130 hours of service.

I was told by Peter that the 350.5 was the sweet spot in the .5 line. It had very similar attributes with the XA series.
