Manufacturer Details

The Audio Note (UK) DAC2.1x Digital to Analogue converter has been specifically engineered for sonic performance rather than technical specification, and fulfils all Audio Note (UK) Level 2 criteria: -

  • Valve rectification

  • Materials and component quality

Audio Note have carried out 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 Audio Note’s 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, they 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 they do is to reformat the data stream to allow the converter chip to be able to interpolate the incoming information correctly.

In other words, the Audio Note (UK) DAC2.1x has no over sampling, no jitter reduction, no noise shaping and no re-clocking. Having removed all of the digital filtering that is required for over sampling, all filtering is done in the analogue domain where it is easier to retain good, wide band phase-frequency and dynamically coherent behaviour. It uses the highest grade Analogue Devices AD1865, 18Bit stereo converter chip solely because they found it to be the best sounding available (yes, even better than the 20Bit versions!).

The filter-interface coils / transformers are of extremely high quality, and are custom designed and manufactured in house by Audio Note.

The DAC2.1x Signature also features an abundance of upgraded components in comparison with the standard edition, including their own Audio Note (UK) Tantalum resistors and Copper coil capacitors used in key areas.

The analogue output has provisions for both single ended and balanced operation, using the best available quality RCA and XLR connectors. To power this spectacularly revealing arrangement, they have incorporated a power supply with vacuum tube 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. Internal components are of extremely high quality, as is expected from an Audio Note (UK) product.
