Just reporting back for anyone else in the same boat. I can't guarantee I've measured this correctly as I've simply watched a couple of how-to videos on multimeters before The Big Measuring Event; in fact, I can probably more likely guarantee I've measured INcorrectly!
For what it's worth, though, I measured ~10mV of DC output on pins 2 & 3 of the XLR output of the Topping E70. Now, whether that's a 'safe' amount or not I the amateur can certainly not say, but assuming the measurement is accurate, the DC output I read personally was non-zero, so I am more inclined to spend a little more and buy another Audiophonics Hypex amplifier that doesn't carry this warning about a lack of decoupling capacitors.
For what it's worth as a counter-argument to my decision, Audiophonics, whom I'd also written to along with Topping, were kind enough to get back to me and let me know that the message about the decoupling capacitor absence "only concerns esoteric or DIY sources without output capacitors".
Thanks again everyone for their input! Much appreciated.

Lower number=better measurement!
