Product Description

LM3886 ChipAmp in external power suppply configuration with integrated volume control, built within two half-size Studio chassis connected by 12, 24, or 36 inch power connector cord. This external PSU configuration minimizes interference, enabling the addition of a volume control without compromising sound quality. Built by hand with meticulous care in our Ohio workshop, this is a fully tested prototype amplifier.

This unit is a prototype. Front and rear plates have been repurposed from other amp designs, so the level of finish is atypical for DALAUDIO, but the audio engineering is of highest quality. We're quite pleased with the sonics with this design. So much so, that we'll give you two weeks to audition it. If you're not impressed, send it back for a full refund. All you're out is the return shipping cost.
