Well, I just got my blue Clou cable broken in and ... (In his best Christopher Walken impersonation): Wow! Wowowow! The bass is extended, the highs are smoother...I think I may have just achieved..nirvana, that is. My system as it stands: Pioneer DVDL-919/Rega Planet (pre-millenial version), Hosa digital cables, MSB Tech Link DAC III w/upsampling and HDCD, Audio Valve RKV Mk II/III (it still says II, but my dealer says it was a III, and it doesn't pop when I turn it on, so I believe him), constantly changing cables (alright, so there's still one definitive piece) -- but I stand by my Kimber Kable PBJ's for now -- and Senn HD600's w/Blue Clou Cable. I can probably upgrade something, but I can't afford to.
Now, I understand the thing about paranoia, so I may get the Red...but, just to repeat the question -- is there _any_ difference?
