Simpelstark AX2 bundle #1 (2 x Amp boards + 2 x PSU boards)

Regular price $65.90

This is the bundle including the bare boards for Simpelstark AX2 V1.32 amplifier and Compact PSU, 2 boards each (dual mono configuration for the lowest noise and crosstalk).

Simpelstark amplifier opens our Delicate Sound amplifiers family.

A specialty of this design is high linearity of every stage and no traditional global negative feedback - only 18db of ODNF error correction. The amp is particularly good for acoustic music - jazz, classics, guitars, vocals, drums, cymbals, etc.

The amplifier is dead silent at idle, which is a big advantage for listening at the low volumes and/or with some high-sensitivity speakers.

If you order the boards we provide all necessary documentation and of course - our support for the build.
