My freshly restored and recalibrated Revox B215 cassette deck would never replace my VPI TNT turntable but honestly, soundwise they're very close musically. Just yesterday I did some recording on my Revox from my favorites tunes using my Audio Research CD2 MKII CDP and just for fun I was flipping the Revox monitor to source and back to monitor again and for the life of me I couldn't hear the difference in sound quality.BTW, I'm not using the Dolby noise reduction at all during the recording process but yet the playback recordings are devoid of hiss noise. This is always been the positive side of the Revox cassette decks especially the B215 model as its recorded music is always silent even without the Dolby noise reduction encoding.
Here's a lab report of the Revox B215 cassette deck...
Lab Tests
The playback frequency response of the Revox B215 with both ferric and chrome-type IEC-standard calibrated BASF alignment tapes measured within +1.5, -0.5 dB all the way from 31.5 to 18,000 Hz. The very slight rise at the extreme treble end shown in the graph on page 42 is characteristic of the IEC tapes, but it is normally visible only with decks that fully and properly compensate for head-gap effects.
Overall record-playback frequency response-measured with our calibrated center-line samples of TDK AD (ferric), SA (CrO2-equivalent), and MA (metal)-was equally impressive. At the bass end there was (as specified) a 3-dB rolloff at 30 Hz. At the normal - 20-dB level, high-frequency response from all three tapes was within +1.5, -1.0 dB all the way to our 20,000-Hz measurement limit. Even more impressive was the response at the 0-dB level (which corresponded exactly to the IEC standard of 250 nWb/m). The Dolby HX Pro system maintained a treble response about 6 dB better than is obtainable from fixed-bias recording. Thanks to the automatic optimizing system, frequency response using the Revox-recommended BASF CR-M II tape was identical to that of TDK SA.
Our signal-to-noise-ratio measurements were among the best we have made. We found that BASF CR-M II gave approximately a 2-dB improvement in S/N, but we have also shown the TDK SA numbers to maintain comparability with our other recent test reports.
