Unison Research Unico DS
Unison Research has always been associated with vacuum tubes, elegant Italian craftsmanship, and a certain old-school approach to music reproduction. Yet the company has never been particularly interested in treating tradition and technological progress as opposing forces. Its latest creation, the Unico DS, is perhaps the clearest expression of that philosophy to date. This flagship digital source combines a network streamer, CD transport, and sophisticated DAC with a fully balanced, Class A tube output stage. At its heart are an ESS SABRE ES9038Q2M converter, advanced digital signal processing, and a proprietary technology called F.D.F. (Frequency-Dependent Feedback). Rather than producing yet another streamer whose main selling point is a slick smartphone app, Unison Research has set out to build a serious source component for high-end stereo systems. The idea is to bring together the precision, transparency, and dynamic capabilities of modern digital audio with the natural presentation and tonal richness that have long defined the company's tube amplifiers.
