The Insight+ EC Preamplifier is our enhanced capability design with silky smooth tone controls that switch out of circuit when not used.

The Insight+ preamplifier circuits give you all the music and nothing but the music. Our earlier Omega series solid-state preamplifiers were wonderful, but we knew we could do better. When faster components with even more current drive became available, it was back to the drawing board for us. In rethinking the entire design we were able to make huge improvements in the linearity, current drive and speed of the circuit.

The Insight+ 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 find all of the space, all of the sounds of the instruments that you'd overlooked before.

Because we use a combination of integrated and hybrid ICs to achieve our musical goals, the cost is much less than you would expect. Of course we use metal-film resistors, selected film capacitors, precision controls, gold jacks, and high-reliability active devices. However, parts alone don't make the product. It is the use of the parts that determines overall quality. We don't get silly about expensive frills that do nothing to improve the musicality or usefulness of the product. Great audio design doesn't have to be expensive, only great.


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. Each audio circuit function (line, phono, inverters) are located on separate purpose designed shielded circuit boards to allow easy implementation of the functions you desire.

The EC chassis has precision volume and balance controls, separate tone controls for both treble and bass, 8 sets of audio inputs: CD, DVD, Tuner, Spare 1, Spare 2, Tape 1, Tape 2, and Special (normally line, but used for Phono if so optioned). There are two sets of tape outputs and two sets of line audio outputs.

  • Source/Tape and Tape 1/Tape 2 Switches - to allow tape to tape monitoring and dubbing.
  • EPL - for switchable external processor loop with dedicated EPL input and output jacks. This allows connections of any signal processor or equalizer without interference with other functions.
  • Left and Right Mono Switches - to get mono audio sources (such as TV and older video movies) to both left and right channels and to quiet noisy FM broadcast and old records.
  • Low Gain - to allow better volume control use with high-efficiency speakers and high gain amplifiers.
  • Filter - to tame the grit and boom from poorly recorded or noisy sources.
  • Tone - to allow you to switch the tone controls in or out of circuit.

The aluminum faceplate 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.
