Analog PreAmplifier

Infigo

Designed to preserve all the beauty of the soundstage.

The Method 7 is our full analog audio path preamplifier that truly preserves all dimensions of the stereo image our other components create.
Full analog audio with the benefits of digital control:

  • Gold contact relays source select

  • 256 steps of 0.5dB analog volume control by switching precision resistors

  • Programmable volume offset for each source to equal sound levels

  • Programmable balance offset for each source

  • Our unique 'audio matrix' allows each input to be used as line level output, for instance to be connected to a recording input

  • Each input can be programmed as bypass input with programmable fixed gain for home theater bypass functionality

  • Programmable loading resistance and capacitance on MC and MM phono cartridges for best sound on phono stage

  • Remote control operation as well as touch screen selection of source and volume

  • Balanced and single ended outputs have separate driver circuitry

The Method 7 combines the most musical analog circuitry connected to versatile digital control. Its firmware can easily be upgraded via a SD card slot in the front. Firmware is available on our website.

The Method 7 is the ultimate companion to directly drive a set of Method 3 amplifiers or Method 6 stereo amplifier.
Its 3 single ended, 3 balanced inputs and phono stage allow for a total of 7 difference music sources.
Lucky number 7.
