Solution for Schitt Loki wall-wart power supply?


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

worth considering?

Would it make sense to use something like the Shunyata Venom Defender or Nordost , NORDOST QK1 QKoil Load Resonanting CoilPower Conditioner, plugged into the same wall outlet with the Cullen?

Suggestions? Other/better options? 

Thanks.

fuzztone: "Tight quarters", here, too!  I appreciate your advice regarding likely return-on-investment. I was simply curious about whether this might perhaps be a neglected "achilles heel" in my system, having repeatedly  encountered the opinion that "wall-warts are bad". 

stereo5: I can't seem to locate the specs you quote on their website. 
Could you possibly PM me a link? 
Not all wallwarts are bad.
The flying dutchman tried upgrading the Silent Angel and said that the stock "medical grade" was better sounding. Schitt DOES engineer their power supplies and I've no reason to change any of my 4 Schitty components.
If you read the "specs" tab for the Loki on Schiit's web site, you'll note that it states their "wall wart" uses a transformer for the power supply.
The owner's manual clearly says: "Do not use any other walwart,,,bad things may happen".
I have mine simply plugged into my conditioner, with no noise or issues whatsoever. A great piece of equipment that I highly recommend.
