What has produced the greatest sound improvement for you?

[RickyV]

I totally agree with @PeterSt on the audio pc as the biggest improvement in SQ. Only I have been upgrading my pc part for part I am sometimes amazed by what a change can do, S.W., apacer industrial ram, power supply. For instance I recently upgraded my diy lps for a different diy lps and the gain in lower noise and 3Dness was really significant.

Over the not al that many years I am playing with pc’s I am beginning to think that maybe the source is being the biggest improver of SQ, If the rest is up to scratch naturally
