That's a good question, and I'm still looking, to tell the truth. Right now, I'm using the phono stage in a NAD C160. I have a brand-new Seduction kit with the constant current options, still in the box ready for me to assemble. So I could go that route. I've spoken to Poindexter about an AudioTropic phono stage. And I've considered homebrew.I want a phono stage that has good components and that looks good, so I'm kinda being choosy. It's a small circuit, so it shouldn't be much money to do it right. Until I've found one I'm happy with, I'm prepared to settle with what I've got.
There are some very inexpensive phono stage amps you could use to get you started, while you're still looking. Who knows, your starter phono stage may be the one you end up liking best. Something like the Hagerman Bugle or even a Radio Shack phono stage would get you by while you continue your search. Be sure to look through the posts in the Turntable forum for more ideas too.
