I have the PS Audio BHK and the Pass Labs X260.8 mono amplifier (2)
I have owned the Pass Labs XA 100.5 and XA 100.2 amps.
I have not heard the Parasound JC-1 except at audio shows. My memory says it was average good sounding. I have not closely evaluated it under well controlled situations.
I can tell you about the X260.8. After reading reviews of this amp, I traded my XA 100.5 and XA 100.2 amps for the upgrade. I really liked the 2 -XA’s. I was just persuaded that I would hear the difference in the upgrade and I had 30 days to return.
I heard such a difference that I called the dealer, Reno HI-FI. I wanted to know why was there such a major difference in all of the audible characteristics of the music I was now hearing. I pissed him off when I said that Pass Labs should be selling this mono at a lower price because the majority of people who listen to music, not audiophiles, will never be able to afford this and never know how wonderful music really can be.
I can find no flaws with the 260.8. I can only listen to the music and truly enjoy it to a degree I never thought would be possible in my home.
Both amps only get slightly warm.
