Audio Reasearch VTM200 Mono Block Amplifiers. 200 Watts of Audio Research power with a perfect combination of finesse, slam, delicacy, and power. Excellent condition and always pampered. Matched set of tubes from Audio Research costing over $2000 recently purchased, which tubes now have only 600 hours on them. My audiophile friend who also had a pair of VTM200's bought a pair of ARC Ref 210's, and he says he really couldn't hear the difference until he had his Ref 210's upgraded to the brand new Ref 250 status, which amps cost $25,900. Silver face plates. Pay Pal add 3%. If you have questions or want to discuss, call David at 405 823 7007.
