BH out1 vs. out2
after some more listen here my conclusions:
out1 - best in high gain mode with LF engaged, SF either on or off depending on music genre or quality of recording. overall pleasingly spacious and warm sound but the output is a bit dirty and there is some loss of fine detail. casual listener perhaps will prefer this output still for most of his or her music. pleasing result and more easy listening here.
out2 - best in normal gain mode (high mode off), both LF and SF engaged (on). clean and very transparent, nearly analytical. overall pleasing neutral sounding and clean output but less enveloping and lacks a bit in bass and bass attack. this output will be fine for people coming from analytical type of listening who crave for very detailed sound. pleasing detail rich and neutral sound but can be fatiguing in long listening sessions.
BH is fine amp which offers nice flexibility and perhaps would suit various types of IEMs, you just need to experiment a bit with outputs before deciding which one is yours. It is a very good amp for its moderate asking price.
