You will, of course, get plenty of suggestions for the phono stages members actually own. That makes sense, though, because we bought them because we found them appealing...it's not just blind loyalty or a need to get others to "agree" with us.
With that caveat, I'm very pleased with my Modwright PH 9.0XT, at around $5k.
-The base PH 9.0 uses two 6C45 tubes and two 6DJ8/6922/7308 tubes, and has a remote power supply connected by an umbilical.
-The upgraded PH 9.0X adds a pair of Lundahl gapped output transformers, removing a pair of chokes and coupling caps from the signal path.
-The PH 9.0XT changes the power supply to a tube-rectified PS. I've noted a significant sound difference with different tubes, and I'm currently using a Sophia Electric Aqua 274B, which I find provides tube depth and fullness while retaining clarity, air, and transparency.
