I've had my TGA SLVR cord for five months and I'm delighted with it. Retail $500 (!). I curently have it on my preamp (Joule Electra) but I'm getting another one for my CDP, and possibly my amps. (Hi Bob!) I haven't tried that many other cords (Coincident, Shunyata Black Mamba & King Cobra, Blue Circle), but now I don't feel I need to. BTW, I also use the Nordost interconnects.
So what does it sound like???? Very open, big soundtsage, huge, solid image... smooth, focused, transparent, no brightness or glare. Balanced. I don't have dedicated lines or a power conditioner. The SLVR is plugged straight into the wall of my crappy circa 1961 wiring. I didn't think a power cord would make this much difference considering my old house electrical system...but it most assuredly did.
You should email Bob and ask him anything you want...he really knows wire and he' a straight shooter. Try him at rcrump@houston.rr.com and he'll hook you up with a local dealer.
The SLVR does take 30 days to completely break-in. Sorry if you don't believe in break-in, but it's true. This cord performed *exactly* as Bob told me it would.
My system: Cary 303 CDp, Accuphase T109 tuner, Joule Electra LA100 MkIII preamp, Meitner MTR101 MkII mono amps, Alon V MkII speakers, Nordost Quattro Fil ICs, Coincident tri-wire speaker cables.
