I have had all GA-0s for a number of years and love them. Sound stage improvements along with sound clarity are excellent as compared to Cardas gold & MIT terminators in my all micintosh system. I just tried the Ag-0 for the ICs between my amps and preamp. To my ear I hear an improvement in "sweetness" of the sound if one can call it that. In doing the exchange of the ICs I broke one of the connectors and have been trying to contact audio metallurgy for repair but have had no answer or reply. Anyone have the same problem. I wonder if they are closed down or just on vacation? anyone have a similar experience?
