PASS and ZYX

Whatever phono stage you get next, make sure it has the ability to change gain settings at the very least. Most offer changes in gain and loading, some even offer the ability to change capacitance. Having a flexible phono stage makes analog a lot easier and more fun. Flexibility is the key.

The Pass Xono is extremely flexible and a great value used for about $2K. The XP-15 is supposedly better, though I have not heard one yet.

I'm using a Pass XP-15 with ZYX 4D low output and my system has never sounded better. As a few have said having a flexible phono is important, I had a fixed phono for years...the Tom Evans Groove. The XP-15 just made life a lot easier for me.

I see you use tubes for your pre and power amps. Did you notice any change in the sound when adding the PASS phono amp? I guess what I am wondering is in an all-Audio Research tube system like mine, will a solid state phono section change the overall characteristics of my system? (I am using Magnepan 3.3s but have the 3.7s on order and should see them in about two weeks.)

For me the Pass XP25 is one of the best phono stages period with all the benefits of SS and none of the drawbacks typically associated with SS. I love tubes for many things but in the case of the Pass XP25 it defies the need for tubes with a natural sound that is dynamic and detailed with absolutely no hint of grain. Detail galore, bass that is unrivaled and an ease of use that only misses a remote that is mostly unnecessary.
