Pass Labs XP-20 or Audio Research Ref 3?

If you are into vinyl, I would tend to use electronics that you find to be the most neutral, transparent and resolving and then tailor the sound slightly with your choice in cartridges.

Hi Barrysandy,Sorry for the very late response. I have owned many Audio Research Preamps over the years. And loved each one of them with much tube rolling fun. You're so right on the very low floor noise regarding the Pass XP-20 which I purchased. It works very well with my current system. Paired with my Cary PH-302 tube Phono preamp it has a very warm and detailed soundstage.

Bo1972,
The Pass Amplifier is a 250XP. It was the (Prototype Version) for the X250.5 that I have just traded in last week. I am waiting for a one year old X350.5

I owned the XP-20 for over 2 years of time. It was a good pre amp, not a stunning pre amp.

Bo, what would you consider to be a stunning pre amp?
