Recommendation for phono stage

Transistor or tube phono stage ? That's the first question.

Sutherland phono stages are usually very good but they might have very high output impedance and will not be electrically compatible with some line stage preamplifiers. I had this kind of fun with Sutherland designed Acoustech phono.

There are many excellent phono stages for $5k, both new and used, it is hard to advise.

I would split your budget and get an SUT and a phono pre. 

For what it's worth, I'm running an Cadenza Black on a SME 309 arm on my GAE & going into a ModWright 9.0. I can change the impedance on the fly to dial in with any LP thats on my platter.

I never load under 100 with this cart & sometimes @ 250, all depends on the recording on the disc. Hope this helps.

Yes that’s very helpful. Just getting an idea of what phono  stage would be a good match for that cartridge and what load is the sweet spot is what I’m looking for

I haven’t heard it but good reviews and has flexibility in settings so maybe worth a look Austin Audioworks Black Swan
