It does have DACs, that presumably operate at the standard frequencies.
Relying on spacing between sample clock harmonics to keep beatnotes out of the passband isn't great engineering practice. I have to do that in a relatively-exotic RF application, admittedly, but I wouldn't advertise it as a feature. :) And I'd never choose that approach at audio frequencies. There's just no need.
1 sample from the EP-133 is 1.0629251700680271 samples at 44.1kHz, or 0.9765625 samples at 48kHz.
(But, again, it doesn't export/synchronize audio digitally, so it probably only matters if directly importing samples.)
