The new Vision SET 400 power amplifier is a uniquely musical high-fidelity amplifier that is designed to accurately preserve all of the energy of a live listening experience.

The SET 400 is our most powerful solid state amplifier. It is rated at 225 watts per channel into 8 ohms and much more into 4 ohms and operates safely into 2 ohms. It’s comfortable paired with any speaker, including speakers demanding a LOT of power.

The SET 400 has awesome dynamic range, definition, and transparency. There is a amazing faithfulness to the spirit of the music, combined with accuracy that makes listing to music a pure enjoyment. The sound stage is life size and so pure that you hear much more of the music in a way that will startle and please you.

Standard configuration includes gold plated machined RCA input jacks, 5-way gold plated speaker jacks, and external speaker fuses. The faceplate is our silver 1/4" thick sculpted aluminum faceplate. A cost-saving 1/10" aluminum black faceplate with a rocker power switch is also available. Both faceplates feature our incredibly durable double anodized finish.

Audio Circuits

Our new Vision SET amplifiers are Class A/B, and are biased as Class A at normal listening levels. The SET name stands for their unique Single Ended Transistor voltage amplifier design. This is our newest design with a simple but amazingly effective bipolar transistor front end followed by a very fast and rugged power mosfet current amplifier section. Bandwidth is flat from 3Hz to 70KHz.

Our new SET amplifiers are uniquely DC stable. This means our SET amplifiers will not generate speaker damaging DC drift even when driven past clipping.

The combination of our design ideas allow the amplifiers to run cooler, last longer, and be amazingly fault tolerant. Eight double-die mos-fet output transistors, standard on the SET 400, handle difficult speaker loads (2 Ohm loads and up). Plenty of power for any rational loudspeaker.

Power Supply Circuits

The SET 400/150 has an oversized high capacity toroid power transformer that is voltage regulated to provide incredible dynamic range, bass extension, transient detail, and air. All of the power supply parts are selected for long life, reliability and operate well within their technical specification ratings.

All new SET power amplifiers have regulated power supplies for all areas of the amplifier including the output transistors which provide unequaled bass control and micro dynamics. There are no unregulated power supplies - anywhere!

The SET 400 operates with standard 120 Volt power, has an IEC power jack, and includes a polarized 120V power cord. For international use a 240 Volt (50-60 Hz.) option is available at additional cost.

Dimensions: 17" wide, 13" deep, 7" high. Shipping weight is 38 pounds.
