Power Cables <$500 for Digital Sources

Of course check the used market as there is thousands out there and thousands more made every day. Different colours, sizes, textures, gimmicks, satisfaction really depends on how many years you wanna play in the rabbit hole. With regards to the brand names, most produce their share of new product by yearly as well. May l suggest week on week off sampling with music you like, won’t seem like such a waste of time.

GR Research power cables are within your budget and work well digital sources.  I replaced my Pangeas with them.  And you can return if you don't like them - the only way to buy cables.

what’s the rest of your system?

Audioquest NRG4 power cables have been as much as 60% off lately and I bought a couple “Open Box” to try and so far they sound good. They were like $140 each.  Another power cable I’ve been using is the Audience F3. They are half price all over, like $150 a piece.

All the best.

The WireWorld Electra and Silver Electra line is a good value for source components, shielded and all OCC copper.

I haven't seen this recommended yet so I'll weigh in:  Ice Age Audio (iceageaudio.com).

I just purchased their "FrankenCable" power cords, along with their OFC speaker cables and interconnects.  Because I replace all three at the same time, I can't attribute the difference I'm hearing solely to the power cords, but I was blown away at the difference in what I heard.  Much better sound stage, and the clarity and detail in the music was mind blowing.  After installing them, I started listening to some music to see if I could hear a difference, and ended up listening for hours.  It was like hearing things for the first time.

The best part is that, compared to many other brands, they are MUCH less expensive.  I can't say enough good things about them (and I also have to admit, I used to be part of the "can wires really make that much of a difference" school of thought). 

I'm listening to music on an EverSolo DMP-A8 > Parasound A51 > Usher Dancer Mini-2 Diamonds.
