I have a Schiit Loki EQ in my system. Because CD SQ varies so much, it makes no sense to me to not have some sort of tone control option.
The Loki has a cheap wall-wart and I'm wondering whether my system might benefit from an improvement in this particular area. I don't "currently" have any sort of power conditioner. Before I bought teh Loki, a buddy brought over one of the top-tier PS Audio power regenerator/conditioner devices and neither of us could detect any resulting improvement in SQ, so I don't think I need to address power conditioning for the entire system.
The Loki wall-wart is plugged into a Cullen Cable outlet receptacle box, along with the power cords for my DAC and CD transport.
I'd prefer not to spend more than, say $400 at the most. This is an area of audio about which I know very little.
There are linear power supplies (some very expensive). Is a more economical option like those offered by Small Green Computer https://www.smallgreencomputer.com/products/5v-12v-linear-power-supply-15w?variant=30287580528674&am...
Would it make sense to use something like the Shunyata Venom Defender or Nordost ,

plugged into the same wall outlet with the Cullen? https://www.musicdirect.com/power/shunyata-venom-defender-stand-alone-plug-in-power-conditionerhttps://www.musicdirect.com/power/quantum-qk1-qkoil-load-resonating-coil
Suggestions? Other/better options?
