VTL ST-150 AMPLIFIER

Product Information
Extra Info

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 represents our pinnacle in stereo amplifier design. The noted VTL quick clean musical sound and exceptional bass punch is delivered here by the 6550C tubes. Exceptionally well suited to triode operation, yet they are also very quick and clean 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 amps are best suited to speakers with an efficiency of 92dB/1W/1m or higher. Try these designs as a great sounding alternative to single-ended triode designs.
• 150 watts per channel.
• 95 lbs, 19" x 10" x 9".

VTL Tetrode-Triode Switching Capability

The VTL range of power amplifiers offer a unique feature that makes them even more flexible: On-the-spot switching between tetrode and triode modes of operation that is easy to reach and user switchable.

At lower volume levels, and with efficient speakers, the sound of the triode mode offers a level of delicacy, liquidity, and sweetness to vocals, chamber and jazz instrumental quartets and solo instruments with 3-D imaging in the mid-range that will get you even closer to the real event.

Tetrode mode offers the detail, soundstage width and depth, and weight to the music that on large-scale orchestral or big band will transport you to the concert hall with all the visceral power and detail rendition of your favorite music.

A changeover switch is provided on the back of the VTL amplifiers to make changing between the two modes a breeze - just power down the amplifiers, flip the switch to the desired mode, and power the amplifiers up again.
