SGD80,000

Good condition with box.

Product Description

The Audio Note (UK) DAC5 Special Digital to Analogue converter has been specifically engineered for sonic performance rather than technical specification, and fulfils 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 are the most unique digital product available today. It uses the most unusual and innovative digital circuit on the market, combined with some of the finest components, materials and power supplies possible. Extensive research into the fundamental properties of the data stream itself have shown beyond doubt that, regardless of the theoretical advantages of the signal manipulation employed in our competitors products, such as higher over sampling, noise shaping, re-clocking or jitter reduction, these corrective measures greatly interfere with the critical time domain requirements of the signal.

Music is a time continuum from start to end which when broken is irreparably damaged, and no amount of clever manipulation can restore it to its original time / frequency / amplitude duration or relationship, regardless of what the theorists may tell you.

As a result, we have developed a way of excluding or bypassing all these corrective measures, to allow the conversion from digital to analogue to be done without any manipulation whatsoever. All we do is to reformat the data stream to allow the converter chip to be able to interpolate the incoming information correctly.

The DAC 5 Special features an upgraded version of the M6 pre-amplifier line stage, using a 5814a (ECC82/12AU7a) and a 6463, both of which are dual triode 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. The analogue output has provisions for both unbalanced and balanced operation, using the best available quality RCA and XLR connectors.

The DAC 5 Signature features an upgraded version of the M6 preamplifier line stage, using a 5814a (ECC82 / 12AU7a / 6189) and a Telefunken 6463, both of which are dual triodes valves. These are coupled to an output transformer, wound with Audio Note (UK) silver wire on a 55% Nickel Audio Note (UK) Supa-Perma C cores. 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. The analogue output has provisions for both usingle ended and balanced operation, using the best available quality RCA and XLR connectors.

To power this spectacularly revealing arrangement, we have incorporated a dual channel power supply with double choke filtering and valve rectification. This technique not only provides excellent isolation between the digital circuitry and power supply, but also provides well-isolated short and clean analogue signal paths. The digital power supply is an exceptionally low noise, shunt-type.

Internal component quality of this calibre has never before been seen, in either consumer or professional equipment. There is an abundance of Black Gate and Cerafine Audio capacitors, and Audio Note (UK) Tantalum film resistors throughout the circuit. Analogue stage filter inductors and internal wiring are all produced with Audio Note (UK) 99.99% pure silver wire.
