Pass Labs XP-20 or Audio Research Ref 3?

Dear Alan,

I took a look at your beautiful set. I see you already use the XP-20. ( I have owned this one for 2 years) Why are you still using the older X-250. Because I think it was one of the weakest parts in your system. I had this one for over 2 months for a lend period. It was not a great amp. The later 0.5 series are so much better. Do yourself a favorite, and buy a 0.5 amp. It will bring your set to a much higher level. I promiss!!!

Agree with Bo1972. I had the X250 for 7 years and liked it very much, but the upgrade to the X250.5 was significant.

Bo,
This Pass amplifier has been modified to a .5 version if you read Alan's system description.
Regards,

Clear, thanks

Nothing wrong with the highs in the XP-20 - a little more emphasis on leading edge than the ARC. I don't mean to suggest the pre-amp is bright or siblant. You already know it isn't if you own it. As typical with tubes, ARC highs have a little more airiness, and sweetness. This may be great for female vocals, less so for hard rock guitar solos. It would be best if you could listen yourself and compare.
