Redkiwi, are you leaving the p8 and ref 9's on all the time? Do you have the units plugged directly into the wall?
This is a must do! I have a silver/copper balanced ic from p8 to amps. I will a/b test soon on all silver to silver/copper ic's. I have all silver for speaker wire right now and plan to play with some silver/copper mix on those also. I have a feeling the silver/copper is the way to go at least on speaker wire. Nuforce's sound is just as transparent as can be. The sound is much more life like and with Schulte's upgraded cdp's you get a great combination. Schulte's upgraded cdp's are excellent with hi end associated equipment, this is the arena where his stuff shines. As you know a cdp is only as good as its weakest link. Send me an email if you would like.
