DAC 2.1x (Signature)

The Audio Note UK DAC 2.1 is available in both standard and signature versions. The circuit features an Analog Devices AD1865N digital to analogue converter chip and employs Audio Note’s 1 x oversampling and Direct From Disc technology. 
 
 
 
The unit also has an input stage with Audio Note’s patented I/V transformer interface and digital input transformer. The analogue section of the unit employs a pair of ECC88/6DJ8 valves in anode follower configuration with zero feedback.
 
 
 
Building on this technology, the DAC 2.1x Signature uses Audio Note Kaisei capacitors and Audio Note tantalum resistors in crucial places and Audio Note copper foil signal capacitors. The signature version also has an upgraded power supply, with a substantial choke filter and valve rectification.
 
 
 
This highly-regarded DAC is available with a face plate in either brushed aluminium or polished black acrylic to match other products in the Audio Note UK range.
