Phono stage good for classical and jazz?

In order so that we can provide you with a useful answer, please describe the rest of your system: what TT/tonearm/cartridge, amp/preamp, speakers and your room?

+1 to BR3098's question.

In particular, without knowing what cartridge(s) you plan to use it's impossible to say which phono stages would be suitable. For instance, the Quicksilver mentioned by Lewm would be suitable for MMs and many HOMCs, but would be inadequate for a LOMC (as he noted).

I have no relationship to them, but I recommend the Liberty B2B. It works great and is in your price range. It does MM and MC. I have one and it outperformed the Krell KRC-HR Reference, Krell KPE, Jasmine and Cullen Modified GCPH. The problem with recommendations is that no one has heard all phono stages, so people just recommend what they heard. If you hear them at shows, they are always in different rooms with different gear and you can't tell what is phono stage and what is the other stuff.

The Liberty B2B has excellent, speed, clarity, and plenty of slam. There is one for sale here on AudioGon:

Pass XP 15 is absolutely wonderful with jazz. It sounds so sweet late at night playing intimately recorded vinyl. Whatever the venue it will be portrayed in very accurate and specific physical space but with the correct musical flow. An alto sax is an alto sax, cello a cello, but you get the specificity of the musician's own style and touch. Wonderful with piano and any keyboards and percussion is amazing. I recommend it highly. Extremely clean, pure, deep, wide and jfet smooth. Lots of gain and loading options and ability to run balanced out which I do. I am good with this pre for long term. Does everything right. Good luck!
