Building guide for this product is available in the Downloads section.
Simpelstark amplifier opens our Delicate Sound amplifiers family.
A specialty of this design is high linearity of every stage and low amount of 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.
The full building manual will be available soon, meanwhile - if you order the kit we provide all necessary documentation and of course - our support for the build.
