I'm using the FX Audio 03 preamp (12V 1A) into the main-in of a NAD integrated amp. Source is rpi + topping e30 + Allo Shanti. Is it likely I can see an incremental SQ improvement by improving power supply to the FX Audio unit? If so, between a better smps, a 12v router UPS, or LPS, what makes sense? Thanks for any pointers.
