VTL ST-85 Stereo Power Amplifier

This compact stereo amplifier, using 4 EL34 tubes, delivers a solid 60 watts per channel and offers a full measure of the “VTL sound,” but at a real world price. Using the classic workhorse tube that was the foundation of the VTL sound, the EL34 models are studies in compact chassis with short signal paths. These rugged amplifiers are capable of delivering an exceptionally large sweet sound space from any satellite, mini-monitor or small floor-standing system. Listen to what one critic called “the weight of the brass, especially the trombones, is sensational”, and “… made me aware of just how good these units are at portraying those subtleties in music reproduction that matter to audiophile music lovers.” We accomplished this seemingly contradictory goal through careful engineering… An audiophile “best buy.”
