IF my unit wasnt faulty (and i srsly hope for smsl it was) its not quite high (like in: "yeah, its a bit high..."), it is way to high (like: "far from anything acceptable").The default noise from the amp is quite high indeed.
but im not going to judge on that one, b/c i didnt test a different unit.
i did, just for the sake of checking the feature out, didnt know it would make any difference in noise... it didnt.Hope you tried to dim the screen to the lowest setting, that makes it much cleaner.
60... ok. for me it made no difference, i had the noise regardless the output.I do agree the noise floor above say '60' on the dial in unacceptable.
whatever, im a bit disappointed by the performance of this smsl device, i had a sh-8 once, and i have to say it was very good (disregarding the power output from the HPA, which was to low for my headphones).
like i said, i COULD probably try a hypex NC122MP based poweramp, but i personally find it a bit too expensive and i essentially need a (at least passive) preamp for volume control aswell so that adds up...
maybe i get my ass off the chair this year and try the audiophonics mpa-s125nc and the "pre-03" active preamp or a passive one...
