Something that has been learned about turntables over years…
PSU, motor and speed control is about maintaining a much more accurate speed. This precision controls “pitch”, which is probably one of the more important aspects of what any turntable does.
For the RP6 and swopping to NEO, some background reading…
Maybe no need to do anything immediately. Just passing on a “top tip”.
But it’s a nice thing to explore, if you jump to a better amplifier, more able to resolve and display small differences made on the TT.
