DAC 4.1x Balanced (Signature)
The Audio Note UK 4.1 DAC is available in both standard and signature versions, with both models offering true balanced circuitry throughout.
The circuit features a selected Analog Devices AD1865N digital to analogue converter chip and employs Audio Note’s 1 x oversampling and Direct From Disc technology.
Special attention has been paid to the power supply section, which uses separate power transformers form the digital and analogue stages, the latter featuring valve rectification. The analogue stage employs a pair of NOS 5687 valves, coupled to a thin-lamination HiB double C-core, copper-wound output transformer.
The Signature model expands on the circuit technology, with valve stabilised power supply, silver-wound filters and an analogue stage with two NOS 6463 Telefunken valves.
A true high-end product, the DAC 4.1x is available with a face plate in either brushed aluminium or polished black acrylic to match other products in the Audio Note UK range.
