Audio Plus Services just announced an addition to their family of brands. Effective immediately, Devialet, a new audio brand from France, will be offered through the exclusive Audio Plus network of authorized dealers in North America.
ADH (Analog/Digital Hybrid) is a new and patented form of amplification developed by Devialet. It is this proprietary technology that enables products like the company's flagship D-Premier to be so slim, yet deliver so much power reportedly.

ADH combines Class A operation with Class D, operating in parallel one with the other.
Class A amplifiers are usually comparatively large, consume lots of power, run very hot, and aren't particularly powerful (in terms of current delivery). Class D amplification, meanwhile, can deliver prodigious amounts of current from a relatively compact, cool-running chassis. Yet while resolution can be excellent, Class D is often criticized for sounding 'cold' and weak in terms of bass depth and quality.
By combining Class A and Class D, Devialet claims they have created electronics that deliver tremendous loudspeaker control and dynamic authority, yet the character of the sound you hear is pure Class A refinement.
