Pass Labs XP-20 or Audio Research Ref 3?

It's easy to be a big fan of both. I have owned the XP-20 and now the ARC Ref Anniversary which likely has a family resemblence to the Ref 3. Both are great preamps but are very, very different sounding. The XP-20's strongest points are an incredibly low noise floor that allows you to hear all the details from the recording. It also has outstanding bass. ARC has great soundstaging, tonal color, and an organic textural quality that are typical of tubes. What you will prefer depends on what kind of music you listen to and the type of sound you are looking for.

Both overrated.
Blah

Barry, how was the high end of the XP-20 by comparison?

Agree it's essentially a matter of preferences/system/room. For some convoluted logic in response to your question: I replaced an ARC LS25ll with a Rowland Capri based initially on Guidocorona's threads stating how he preferred the Capri to the Ref3. After enjoying the Capri for three years I have just replaced it with a Pass XP-20 to go with my Pass X250.5, which is why my Capri is now for sale. So that's a comparison that crosses two systems and two listeners.

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!!!
