What separate tube phono stage do you use ?

Tavis Design has I believe 3 models now.  The 2 entry levels may be all you'll ever want and the high end has received terrific  reviews as well.  Read about the owner / designer and you'll be sol as the type of guy you would like to bus equipment for you.

Can't see why one would eliminate a whole array of potential candidates by insisting on tube only. Shouldn't the question be - what are some of the best sounding phono pres regardless of what devices happen to be inside them?

I use a CJ Premier phono in one system and it is very good, but not as good as the phono pre in my main system, which is solid state.

Rogue Audio Ares with Magnum upgrade, NOS tubes. Very happy with it.

I can easily understand why someone would insist in tube only. Unless your budget is unlimited, you can not just sample phonos endlessly, you must have some idea of what you want.

SS makes sounds, Tubes make music; to some people, sounds sound better than music, plus they dote over the lack of sound, which they call "silence", and nothing is quieter than SS, it exceeds in making no sounds, but since it wasn't making music, the matter is moot.

Music lovers love tubes, and tubes are cheaper because you can double the quality of a tube phono with NOS tubes.
