Very interesting. Focused FiiO Q1 MkII because of its price together with digitalised volume control, dac/amp + amp capabilities, and balanced output chance (i don't own any balanced gear yet).
pity its output impedance is over 1ohm (not too high though) and balanced hissing.
Yeah, it could also be lower for my very personal standards that prefer 0.5 Ohms and below - but it' not that 1.2/1.3 Ohms are a high number at all, and while my inner output impedance perfectionist is slightly paranoid seeing that, my common sense tells me that it's still a value that is a good bit lower than what other devices have in terms of OI.
Most multi-BA models that aren't as much diva-like as the Triple-Fi 10 shouldn't show much deviation from the unloaded measurement at all.
