Preamp suggestions for Pass Labs XA100.5

I use an Atma-Sphere MP1 with XA60.5 and it works great. Very quiet and dynamic. IMO one of the best preamps available. The phono is very good if your cartridge has a reasonably high output, otherwise you may need a step up transformer to keep noise at an acceptable level. I ended up using a Boulder 1008 phono for my 2 lomc, and the Atma Sphere with my mono cartridge that has around a .9 mv output. Ala in all, highly recommended.

I've never been too impressed with Pass preamps. I've owned both their amps and preamps, and like the amps much better. I would look at: Ayre, BAT, Aesthetix and maybe Audio Research.

Mark levinson 326s could be considered.

Thank you for all the responses--much appreciated.

I have been tempted to buy a Conrad johnson preamp. I know CJ preamps are supposed to be more tube like in their sound comapred to Audio Research. I wonder if a cheaper preamp in their line such as ET3 or ET3SE would be a good match. I guess it might be a toss up between Conrad Johnson & Audio Research (LS27).

I'd check out the VAC Renaissance pre amp for sale on this site. I think it is a Mk1, so price should be lower than the $4500 asked. This a a superb pre amp with an excellent phono stage thrown in.
