They're pretty hissy with the Q1 MkII balanced output as well. In fact they're hissy on my SE100 as well which is interesting because it's meant to have a lower OI than single ended (1.5ohm SE vs 1ohm Balanced). The balanced cable I'm using isn't as expensive as ALO stuff though. So I'm thinking either a) balanced introduces more hiss in general or b) the quality of the cable I'm using ain't that great. The only evidence I have to support a) is that running another all BA IEM over balanced with the same cable also gets more hissy, and the same goes for my FiiO FH5 (which is a hybrid) but not nearly as much.
Either way, for now I'm quite happy with the standard litz cable going single ended as I get little to no hiss
To be honest the only reason I ran balanced with other IEMs was to be able to play music at lower volumes. However with the litz cable I already get that in spades, which I reckon is testament to the quality of the cable.
Which leads me to a question I'd like to put forward to my fellow owners: does anyone run primarily balanced with their Andros? If so what's your source, cable and how is the hissing (if any)?
