CHORD CHORDETTE QUTEHD (£990)

摘要

Robert Watts' WTA interpolating filter and Pulse Array DAC technology has evolved over the years and is largely responsible for the very fine performance realised here. Via S/PDIF, it enjoys a high 3V maximum output, a low 65ohm source impedance, wide 111 dB A-wtd S/N ratio and impressively low 0.0007% distortion through its midrange [red/black traces. Graph 1]. At high frequencies the analogue stage is slightly 'stressed' [blue trace, Graph 1 ] and so distortion is higher at peak output (0.017%, 20kHz) than at lower levels (0.002%, 20kHz/-20dBFs).
