RED WINE ISiiBELLINA LFP-V (£1395)

摘要

While Red Wine's NOS and HRZ modes have utterly distinctive technical footprints, so does the triode-based output stage that follows them. In HRZ mode with the Wolfson WM8524 DAC offering a low-order digital filter (more post-ringing than pre-ringing but with a limited 39dB stopband rejection), distortion is still dictated by the tube at 0.08% (OdBFs, peak output), falling to 0.015% (-1 OdBFs) and 0.0045% (-30dBFs). Distortion increases at low frequency to 0.3%/20Hz and high frequency 0.12%/20kHz, the former linked to an increase in the analogue output's source impedance that rises from 150ohm (midrange) to 900ohm at 20Hz.
