The urge to tinker is awash. What TT might better mine and why?

Try an idler drive turntable. Garrard 301/401, Lenco, etc

The sound is more dynamic

Why might an idler drive TT be superior to what I have?
I am a little surprised that nobody has come forward with their particular TT of choice and giving some good solid reasons for choice of same.

Definitely not going to splurge any moolah without some basis for what I can potentially expect.

Seems like there are mixed reviews on your table. If I was starting from scratch, I would look at a 301/401 with new massive bearing and heavy platter in the right plinth with a top notch arm. I don’t know your budget but as a starting example of cost, my rebuilt 401 with custom idler in a slate plinth and decent arm set me back less than $4k. It sounds wonderful - musical, transparent, resolving, and utterly involving. It is also a respected reference class transcription table that has stood the test of time.

Side bar question, how do you like the Goldnote PH-10? Did you splurge for the separate power supply? 

@dmix I believe the OP has the GN power supply.

@uberwaltz Why not try moving your speakers onto the tile for better rigidity?
