MEASURED PERFORMANCE
Frequency response was flat to 20kHz our analysis shows and this player uses the QBD76 DAC apparently, which gives identical results. A modification to pulse performance gives a pronounced roll off at high frequencies, measuring -0.6dB at 10kHz at -2.6dB at 20kHz when testing with a raised cosine pulse, identical to Chord’s now discontinued DAC64, a convertor that is highly regarded for its almost analogue sound. So the Red Reference III player combines elements of both it appears.
    Distortion levels were low throughout the player’s entire dynamic range, measuring 0.0005% at 0dB through to 0.18% at -60dB. There was obviously little noise in the -60dB signal and as a result of this and low distortion EIAJ Dynamic Range measured a very high 101dB. Output was high at 3V.
    The measured performance of the Red Reference is exemplary, in keeping with earlier Chord digital products. NK
