VTL

Performance ST-150 Stereo Amplifier

Over 150 watts per channel (300 watts of stereo power), this stereo amplifier offers superb musical clarity and plenty of power in one compact chassis. Utilizing the finest quality parts, and entirely hand built by experienced craftsmen, the ST-150 is VTL’s offering of a high value, high power stereo tube amplifier. The noted VTL quick, clean, musical sound and exceptional bass punch is delivered here by the 6550 tubes. Exceptionally well suited to triode operation, yet they are also very dynamic and fast in tetrode mode, these VTL amplifiers are well-suited to smaller electrostatic panels and dynamic speakers not requiring high current. For commanding performances on the midrange and clarity on the top, VTL wins hands down. In triode mode, the amp is best suited to speakers with an efficiency of 92dB/1W/1m or higher.

“… one of the rarest tube designs …”

“The power amp continues the VTL tradition, succeeding in the recipe of getting the advantages of the tubes with some of the positive elements of transistors.”

“In tetrode mode the ST-150 has a particular muscular and phantasmagorical sound. We would describe it as Technicolor with shiny timbres, surgical detailing , building a huge soundstage spacing all the musical images with incredible accuracy.”

“Changing the function mode in triode, the sonic character changed. It turned to a pure tube design with all the sweetness and magic we expected from a very good tube having all the dense timbres that enchant us in the triode tube.”

"… But beyond this sensation of the musicians’ presence is another kind of harmony created by these designs, the kind that, taken altogether, creates a seamless sense of bottom-to-top tonal coherence, dynamic push, and resolution to create a thrilling sense of aliveness and of the music-making process… for these ears (and this heart) VTL’s TL-5.5 Series II Signature preamp and ST-150 power amp are remarkably successful at delivering on all fronts—thrilling in the ways that can arouse the latent audiophile within while drawing him deeply into all spectra of music."
