"And also with analogue it seems that the more you go up the chain the better it gets. There almost doesn't seem to be a point price wise where there isn't an incremental improvement”
Analog playback involves electromechanical machinery, the quality of which, relies heavily on very precise parts tolerances. As long as a part milled to .001 spec sounds better than .01 and .0001 sounds better than .001, it will always be possible to improve an analog playback system just by spending more on precision parts and fitting, IMO.
