I’ve owned the XP-20 for about 1.5 years now, picked it up used for $5k. Swapped out from a McIntosh c2500. I’ll second Karl’s sentiment, the XP-20 is dead quiet. Literally, you can hear what “black” sounds like. It’s extremely transparent, and doesn’t over do any one sound characteristic. Not too bright, no bottom end bloat. Quite literally, it’s perfect to my ears.
PASS LABS XO.2 Preamplifier 3 Chassis or Pass Labs XP-10
I am looking for a used Pre from Pass Labs. The question is for those with experience in both or with one of the above mentioned. I don't want to spend $4500 for a XP-20 or more. I want to stay in budget. I can get a XO.2, the 3 chassis classic reference or a newer XP-10; and don't presume newer is better. I'm okay with older if it does what I want. My future amp is a First Watt F7 or Pass XA. I'm looking for feedback on the Pre's.
