Performance ST-85 Stereo 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.”

…The final ST-85 has in my opinion the characteristic sound of the great VTL which is quick and detailed enough without strain, open, natural, able to engage with any kind of music as long as the speakers are not inefficient or that the listening room is significant in size (in this case, you should consider products that are more powerful). But I remember that in an environment of about forty-five square meters what would be a decent local home dedicated to music, the ST-85 connected to the pre TL 6.5 and the electrostatic speakers Quad 2905 was more than appropriate and worthwhile, the ST-85 even with genres as demanding as opera played in full faculties, I never had the feeling the sound was limited to only 60 watts per channel…with a power of 60 watts per channel, which in the golden years of the valves was the maximum, and with a sound as that of the VTL, which is a reference, I recommend the ST-85 as a ‘bestbuy’ for those who want to make the jump to valves and ensure that the investment in time as well as in quality would pay off."
