GR Research Power Cables

This will be the first review of this kind I have ever written. I just received my second and third GR Research power cables in the mail today. These are quite simply the best value of any component or cable I have ever purchased.

I put the first one on the amp. It replaced a similarly priced well regarded cable. No contest. More air, better separation, more dynamic. Across the board better, significantly better. I quickly ordered two more, wondering how they would sound on my DAC (Lampizator Atlantic TRP) and CD transport (Sim Moon 260D). On the DAC the cable being replaced is almost 3 times the cost of the GR Research cable. Again, no contest at all. The GR Research cable wins hands down in every respect (the one caveat here, and I hesitate to mention it, is the soundstage is still a little messy. But this is with almost 100% certainty a break-in issue).

No affiliation with the company, or industry for that matter. Just very excited about such a solid and affordable product. There are no reviews online and for those looking into them; I wanted to add a touchstone that might be of help. They have some great videos online as well that are worth watching.

That's because the higher end Furutech are rhodium plated, and the lower end gold plated.

I do not prefer the rhodium plating on power connectors, it introduces an artificial brightness. Years ago LessLoss audio did a paper on the plating effects of power connectors and came to this conclusion. They were right IMO.

@fleschler You said at Grover they found an all copper plug that sounded best. I too found the same thing- that pure copper plugs sounded best, even better than gold plated. But the cheaper ones can tarnish over time, that is the main issue with them.

The ATL pure copper plugs (ETP with red band) seemed good but I’m not sure they are still available.

Well, I’ve been using Grover’s copper A/C & IEC plugs for over a decade and I’ve only cleaned the A/C ends twice. Not bad tarnish either. I don’t know what the brand is but he says they’re the best quality Taiwanese plugs he’s found and after trying so many rodium, silver and a gold plug, he did find a quality one (some other copper plugs had scratched pins or were too soft and didn’t hold a clamp as well).
