Thanks guy,s for your response and help. I may be wrong here but some our talking about cds. I use the purist cd periodically and it does work.
Somebody was telling me to do the actuall equipment. Which makes since.One day i disconected my active sheilding cable from my interconnects, and without thinking i tried to just plug them back in. Oh what a terrible static sound came out. Then i remmembered i had to turn off the box to reconnect the cables do to grounding. When i turned it back on the system sounded better then ever for about 3 or 4 days then went back to just great.
what happened? and how can i do this again properly.
