Stealth Dream V10 'Power' on Preamp?

Can't hurt a thing to try the PC on any selected audio component. Yes, the sound will very but I don't know the sonic differences between the "power cord for amp" vs. "power cord for preamp". The PC for the amp probably uses a larger gauge wire. I would think it would work well and still sound good regardless of the chosen component.

Thanks, I guess I symply should give it a try...

I am also curious about "high current" cables for amplifiers. Would they also be possibly advantageous at all for very low power amplifiers

Why not send it back to the seller for a refund? Stealth designs the ground path for star grounding, hence the Preamp version has the cleanest path to ground, while the amp cord has a bit more resistance, and the digital cord offers even more resistance, to keep digital garbage from entering the AC line via a ground path. Sure, the cable will work on your preamp, but not as designed. For the money that those cords cost, you should get the proper one for the proper function.
