Audio Note (UK) Digital to Analogue Converters Ever since its introduction, we at Audio Note have been highly critical of digital music reproduction. This dissatisfaction was the instigating force in our quest to make digital playback more dynamically realistic and less fatiguing.
DAC5 Special Congratulations on your purchase of the Audio Note (UK) DAC5 Special Digital to Analogue converter. It has been specifically engineered for sonic performance rather than technical specification, and fulfills all Audio Note (UK) Level 5 criteria: Pure Class A operation Zero negative feedback Single Ended circuit topology Valve rectification Materials and component quality The Audio Note DAC5 Special is the most unique digital product available today.
DAC5 Special continued… The DAC 5 Special features an upgraded version of the M6 preamplifier line stage, using a 5814a (ECC82/12AU7a) and a 6463, both of which are dual triodes valves. These are coupled to an output transformer, wound with Audio Note (UK) silver wire on a High B C-core. With a 33:1 step-down ratio, this output transformer not only has exceptionally wide frequency response, but also just about the absolutely best dynamic transfer function possible.
CONNECTION Special Note – Make sure that all connections are tight and clean. For best results use good quality audio interconnects. Although it is perfectly acceptable to use cables manufactured by other companies, for best results and performance, we recommend our own Audio Note (UK) range of interconnects and loudspeaker cables.
