Forgot to mention that the player before Ayre was the the Reimyo CD777. Also a very good CDP but the Ayre was slightly better and played SACD and DVD-A.
And yes power cords are very important, Before the MPupgrade the Electraglide Ultra Kahn II was very good on the CDP. After the upgrade PAD Dominus was better.
For years the Ayre CDP was my reference beating, as I said, some of the worlds best CDP, but now I have discovered the Nagra CDP. It is even better that the Ayre. I love my vinyl setup Hanss Acoustics T60 TT/ SMEv/ Clearaudio Goldfinger wich is superior to any CDP BUT the Nagra comes closer to the vinyl sound that any CDP I have tried with a warm yet detailed "analog" sound!
