I'll make the concession that magnetic track does have the upper hand on 16-bit, 44.1 khz (or 48 khz for film) digital audio in terms of signal-to-noise ratio (by 6 dB) but ONLY with Dolby SR and properly set up Inovonics. At a 185 nW/m reference it still loses 3 dB headroom in the midband compared to 48/16 digital audio. I maintain a few Magnatechs and Rangertones and have done the setup and measurements.
Bandwidth-wise on the lower end, digital soundly trumps full-coat mag.
Now consider this practically speaking: make one analogue transfer (of which many occur during the sound editing process) and make the same statement. How's that for perspective?
Sure, magic happened in the 1930s with the Shearer horn no doubt. Magic also happened when we replaced our VOTTs with JBL 4675s kindly donated by the Edwards cinema chain in our university theatre/ dubbing stage as well.
Doug Sax is just one respectable opinion of many in the recording and mastering world. I can drop names as well - how about Walter Jung or the late John Eargle, the latter of whom is an Altec alum, Eastman grad, electrical engineer, past AES president and fellow and Grammy winning classical recording engineer?
