I have Adcoms 515 and they do NOTHING! I find good wall outlets do better than 515! I currently use U/O and I'm very pleased with them along with my P-600. I also find the U/O work best out of the P-600 and not before. Further improvements are obtained with good power cords on the U/O and Power Plants. Happy Listening!
If your interested in 515, I have two and would let go cheap!
