The DA-910 is the first CD player we have tested whose designers evidently took the view “So what if we don’t know why it works, if it works, do it!” Instead of two-times oversampling of the playback pulses, this one samples four times, at 176.4kHz (footnote 3). Instead of one, or even two, power supplies for circuit isolation, it has three. It has separate D/A converters, one for each channel. It (of course) uses digital output filtering with a gentle, final-stage analog filter (Look, Ma, no ringing!). It has a completely DC-coupled analog section, neatly sidestepping the issue of capacitor audibility (of course, no one can hear capacitors!) by getting rid of them entirely. And, perhaps most controversially of all, it uses extensive shock isolation for its disc drive and optical system, to minimize the “possibility” that structure-borne vibration of those elements increases the incidence of uncorrectable disc-read errors. In short, the DA-910 is designed in much the same fashion
