I have just upgraded to the PS Audio Power Port from Hubbell hospital grade, on my amp only. I have a dedicated 20A line for my amp, and a JPS Labs Power AC. I bought only one Power Port, Tubegroover, because I am a skeptic, and I figured this was unlikely to make an audible difference. But I'm also a sucker for cheap tweaks, and while $50 is a ton for an outlet, it's only $50. The jury is still out, but I think I'm hearing a bit blacker backgrounds, and a bit more depth. No earth-moving epiphany, for sure, but it's only been a couple of weeks. If I decide it's worth it, I may another in front of my front end line conditioner.
Any PS300 owners who upgraded to Power Ports?
