A quick note on gain: what you need and what sounds optimal can be slightly different numbers.
Something like 66db to 70db gain is common for a MC Phono these days. The Precious is 53db gain ( all tube ) and a 1:10 SUT is 20db so you're at 73db. That's plenty...but a 1:20 sut may sound better or even a 1:40...not because you need that much gain but due to a set of variables at play. On the other hand you can overdrive the gain too
