The TT PSU did make an audible improvement. The improvement is more subtle than the new motor. I have some old habits to break such as no longer using the switch on the table but the switch on the PSU. It is very easy to push a switch and the table speeds up to 45 rpm. Better performance and greater convenience along with the absence of pops when turning on the ttable.

I have not listened long enough to evaluate it in depth but my first reaction was the music sounded simpler. After a few sides I realized there was lower noise and musicians were more focused. Maybe not so much focused but cohesive. There was less blur which eliminates a kind of audible ghosting which sometimes made it sound like there were more musicians than there was. Speed stability is a very good thing.
