Sg69; Others have answered your questions. I will just add that Syn. Res. Master Couplers are one of the original power cords that started the "Craze" and made believers out of many. There are now a ton of them available here on Audiogon for $150-180. They are still excellent cords and I have them on all components (4) in my $40K system. After putting in a dedicated AC and ground system the Master Couplers made a huge improvement. I started with pre-amp, then amp, and front end stuff. Cheers. Craig
