Vision RB Preamplifier

  • Regular price $899.00

The Vision RB preamplifier has the best solid state preamplifier circuits we have ever designed, packaged for audio purists embracing minimal setups and anyone looking for affordably priced, astonishingly detailed and musical sound.

It features discrete solid state Class A audio circuits, thermally balanced and outrageously musical. It also has a new power supply board with three times the power reserve and built in ultra low distortion headphone drivers. The Vision preamplifier circuits give you all the music and nothing but the music.

The Vision RB preamp has even more of the transparency, dynamic range, linearity and pure music for which Audio by Van Alstine has become known. Listen to all of your recordings again and you will hear acoustic space and musical nuance in a much more real and involving way.

Even with the extra effort to provide true discrete audio circuits (no ICs) to achieve our musical goals, the cost is much less than you would expect and the performance much better then you would expect.

Power Supply and Layout

The power supply features a toroid power transformer feeding a full wave diode bridge followed by large smoothing capacitors. These feed plus and minus 15 volt regulators followed by more large smoothing capacitors and extensive RF decoupling. The power supply and transformer are located as far as possible from the audio circuits to provide further noise isolation.

RB Chassis Design

The RB chassis has a precision volume control, selector switch, four sets of line level inputs (with one set being used for the optional phono section, if specified) and two sets of line audio outputs.

The Vision RB comes standard with a high quality built in headphone amplifier.

The aluminum face plate is finished with our incredibly durable double-anodized process. All input and output jacks are gold plated and a removable IEC power cord is provided.

Dimensions: 17" wide x 12" deep x 3.5" high. Shipping weight is 17 pounds.
