Pass Labs XP-20 or Audio Research Ref 3?

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.

Thank you all for getting back to me regarding my post.
Have a great July 4th.

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
