My only experience w/Oyaide cables has been truly excellent: I was using a Billy Jeans digital/coax cable for some time to connect the output of my S/PDIF converter (Musical Fidelity V-Link 192/24) to DAC (Audio GD NOS 19). I was happy with that, finding coax input to this DAC to sound better than USB or glass.
Anyway, I heard about an Oyaide silver coax cable on one of the headphone boards (DR-510). It cost 5-6X what the BJ cables did, but I ordered one. Instant success. Heard subtle but unmistakable improvements--a little better bass; more articulate/refined sound overall w/better resolution; better treble.
Wasn't aware they made power cables--just bought a used "Audio Art Power 1 Classic," which I'll wire into my system in a couple days. But based on my very positive experience w/Oyaide's coax/digital cable, I'd be inclined to try other of their cables...
