Would an upgrade of P90SA to the MkII, with wiring, bring about a SQ improvement as well as the elimination of the crackle I get when turning one of the knobs? My system is very responsive to subtle upgrades as I recently discovered when buying the MCRU PS for my DAC.

HP:Grado SR 325e, Chord Mojo.
Analogue: Rega Planar 3, Denon DL-110, NVA Phono 1, NVA SSP.

Yes.

A subtle but worthwhile improvement in clarity and separation.

Silent and smooth operation...

Seems like it will be well worthwhile. As I will not be home much until November it will be in a couple of months time.

I'll have to start saving as well, I really don't like the clunky feel and of course the crackles.

Tomasz recently upgraded my P90sa with the new Seiden switches, load resistors and internal wiring.

After the upgrade I have not needed to turn off my Sky box when listening to vinyl (I used to get interference). Nothing else changed or moved, so I can only put it down to this.
