Power supplies and cables - observations, considerations & commentary

Thanks Barrows, so a good LPS that minimizes the backwash into the AC side should do the trick? And the output of the LPS1 will be the same regardless?

 

Did I get it right?

 

While I want a nice LPS like everyone else, I'm wondering if plugging the iFi iPower into a filter like the AC-7A would eliminate/mitigate the kick-back-into-the-AC/system noise issue?

 

This filter was recommended by Jim Smith, author of Good Sound:

So in theory to stop the contaminating "backwash" noise you'd plug the iPower into this and plug this into AC.

 

Is this conceptually accurate/effective? Would it in theory help sound quality?

In my particular system, powering the mRendu with an iFi iPower, the AC-7A made a very positive improvement to the sound when added to filter any SMPS backwash into the AC mains.

 

@MikeyFresh Thank you. (So great that everyone is so helpful here.) I'm trying to eek out some more high freq. transparency and attack from my system. I swapped an interconnect and wow got a ton of it plus prat, but the bass receded (not just balance tipping)...sigh. Y'all know the drill.

 

Anyway, between these filters and LPSes there is plenty to play with. Cheers!
