Cost me a tenner, was well worth the outlay.
If you are talking about the one RA does that looks like a 12A plug then I had one of them. I didn't think it damaged the sound but then I didn't find it did anything at all.

I got a Power Inspired AG500 last week. It's a 500W mains regenerator and UPS.
I have my Sky box, blueray, Dac, EQ and Smart Tv plugged into it and it's only running at 44% of its load capacity.
They do an AG1500 which would suit amps.
The AG500 has improved the picture quality and sound quality of my system. A bargain in my book.
