I said I'd share the experience if I did any experimenting - now there's something to report. Having just removed my old-but-trusty Adcom GFA535 (100w into 4 ohms) and re-installed my two nOrh L2 monoblocks (>350w, same impedance) I tried a half meter of Tara Labs Quantum 66 from the Yaqin buffer in place of Kimber PBJ. Sound: smooth and laid back; some loss of sibilance and presence on male voices on PBS Friday evening talking heads shows. Maybe it was the nOrh amps, which have been out of the system for over a year (don't get me started on why)? So I turned off the Outlaw, unmuted the Panasonic plasma, quickly swapped the Kimber PBJs back in, and turned on the Outlaw again. UNMISTAKABLE improvement in male voice quality, and the credits music suddenly had more space, plus the sense of power the nOrhs can give. So can cables make a difference? They sure did for me!
