Jafant,
My system took a dip in performance. The reason is because when I sold the RGPC 1200C, I replaced it with a Transparent Audio PowerIsolator MM, which only has 2 outlets. And even though the Dac & the Music Server have jumped in performance, the soundstage collapsed a bit & became less than stellar. Why? It collapsed a bit because I also sold the Analysis Plus Power Oval 2s, too. So I'm using stock power cords for my amps. Blah... I ordered one TA Premium PowerLink, and expect to pick up 2 more. That way, I can change the amp's and preamp's power cords at the same time. Also looking to upgrade some of my cabling to TA Ref XLs. Big changes coming really soon.
