Recently there was an audio shootout at AudioJerrys. Two Carver ZR-1600 amps (one modded by EA and the other by RAM)and an ARC 200 amp were compared.The Eastern Electric Minimax VS the SAS Audio Labs 10A line preamp was also hightlighted.
Checkout Audiocircle/critics circle/Shootout at AudioJerry, or
