For sale is a Naim DAC (Digital to Analogue Converter) which is in very good condition and perfect working order. This was used in a secondary hi-fi set up, which I have recently upgraded, and so it is no longer needed. As you can see from the photo taken from above, there are some light marks on the top. The front panel looks good - just some light silver lines on some of the top and bottom edge, which look more much more pronounced in the photo of the front of the unit (which was taken from an angle) - when looking direct front on you wont really see them. If youre reading this then you probably know that this an awesome sounding DAC. The full specification can be found below. I dont have the original box, but it will be very well packaged for delivery. I have been an ebay seller for over 15 years and have 100% rating, so you can buy with confidence. Collection from E2 (just north of Shoreditch, London) is possible. Feel free to ask any questions. ----- Capable of partnering and upgrading a wide range of Naim Audio products, the DAC has more in common with our CD players than with any conventional DAC. Its Burr-Brown converter chips, for instance, are also found in our flagship CD555 CD player. The DAC overcomes the jitter inherent in standard digital connections by reading data independent of its timing signal. Its digital filtering, based on a 40bit floating-point SHARC DSP chip running unique Naim Audio code, sets new standards in its class. Our DAC is now DSD compatible and able to play 64 (2.8MHz sample rate) and 128 (5.6MHz sample rate) files; the upgrade required significant optimisation of the core DSP code which has also improved its sound quality. If the DAC’s music performance is extreme, its flexibility is just as remarkable. With eight S/PDIF and two USB inputs, it’s adaptable to any system configuration and can grow to meet any need. Features Eight S/PDIF inputs for digital sources like games consoles, set top boxes and hard disk serversTwo USB inputs (one front, one rear)40bit SHARC DSP chip handling filtering and oversamplingPlays audio files at up to 24bit/768kHz resolutionFront-panel input controls adapt to become playback controls when iOS or USB devices are connected Technology & Craft The Naim Audio DAC is the end result of several years of research. It introduced several original digital music technologies that have since gone on to help inform the development of an entire range of streaming products. The DAC overcomes the jitter issues of S/PDIF by reading the music into a rotating data RAM buffer independently of its timing signal and reading it out again clocked by one of ten extremely low noise, fixed frequency crystal sine-wave oscillators. The data entering the downstream digital filtering and DAC chips is then completely isolated from the incoming S/PDIF jitter. The Naim Audio DAC also suppresses RF noise from S/PDIF through electrical isolation of its DSP front end from the digital to analogue converter and analogue circuits. Each element is also run from separate power supplies. The Naim Audio DACs digital filtering is handled by a powerful SHARC DSP chip running unique Naim Audio authored code to create an ultra-high precision 40-bit floating point filter. The filter over-samples by 16 times on 44.1kHz data and provides stop-band attenuation of 180dB on all data. Following the digital filter are the two mono Burr-Brown digital to analogue converter chips, as used in the CD555 CD player. Finally the Naim Audio DAC features a very high performance, low noise, and low distortion fully discrete analogue output stage.
