Onkyo A-9755

The benefits of digital amplification have been recognized by the audio industry for some time now. With minimal energy, digital amplifiers can achieve efficiency of up to 90%. Without requiring large heatsinks, manufacturers can now turn their attention to introducing new, more compact and slimmer solutions.

Onkyo has used another approach to design digital amplifiers. Utilizing its VL (Vector Linear) Digital technology in conjunction with the “Pure Stream Power Supply” concept (featuring two large transformers), the A-9755 represents a truly unique approach to next-generation digital amplifier design.
