The VT80SE is designed to be the Audio Research amplifier with the widest appeal to the greatest number of music lovers worldwide. By combining world-class performance with flexibility and features like auto-bias, the VT80SE has been an amp that is easy to take home and just forget as you enjoy your music collection again for the first time. The VT80SE expands on the phenomenal performance of the original VT80 with the addition of KT150 tubes instead of KT120. The KT150 improves on sound quality and life span, unparalleled at 3000 hours.
The auto-biasing capability of the VT80SE allows for the use of other tube models also; KT120, KT88 and the 6550.

Specifications

POWER OUTPUT
75 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 75 watts, below 0.05% at 1 watt. (Note that actual power output is dependent upon both line voltage and ‘condition’ i. e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)

POWER BANDWIDTH
(-3dB points) 7Hz to 60kHz.

FREQUENCY RESPONSE
(-3dB points at 1 watt) 0.7Hz to 80kHz.

INPUT SENSITIVITY
1.4V RMS BAL for rated output. (25dB Bal gain into 8 ohms.)

What sonic improvements will you hear with the VT80SE? As Audio Research's Warren Gehl said, “More music!” Tonal color, detail, dynamic swing and clarity are all improved, along with a bigger and more robust presentation. The music gets better, in every way.

If you’re in the market for a tubed power amplifier, do yourself the favor of auditioning the VT80SE. In my opinion, its durability, performance, and resale value all contribute to its excellence.

The Audio Research VT80SE looks great, sounds great, and is built like the proverbial brick outhouse. Its automatic bias circuit makes it far easier to use than most tube amps, and its individually fused tubes protect it against catastrophic tube failure.
