Vision SLR Preamplifier

  • Sale
  • Regular price $1,299.00


The Vision SLR preamplifier has our best-ever solid state preamp circuits in a stunning fully remote controlled chassis.

The Vision SLR preamplifier takes solid state preamp circuits to a new level of musicality and user convenience.

The  Vision SLR has remote volume, remote input switching, remote power, and even remote panel light dimming. Our lovely custom silver faceplate is standard, along with premium quality RCA jacks.

The Vision circuits feature 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 low distortion headphone drivers.

The Vision SLR 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 Vision 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.

SLR Chassis Design

The SLR chassis features a precision remote control volume control along with five sets of remote switchable inputs and two sets of line audio outputs. Additional functions include:

  • A precision balance control.
  • Mono/Stereo - to get mono audio sources (such as older TV and other video sources) to both left and right channels and to quiet noisy FM broadcast and old records.
  • Low Gain - to allow better volume control use with the high-efficiency speakers and high gain amplifiers.
  • High Filter - to tame excess brightness from low quality sources.
  • Low Filter - to deal with warped records and turntable rumble.
  • Support for tape monitoring.
  • A built-in high quality headphone amplifier.

The 1/4" sculpted aluminum face plate is finished with our incredibly durable double-anodized process is standard. All RCA jacks are premium quality, gold plated, heavy duty parts. A removable IEC power cord is standard as well.

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