I have received my Shanling H2 last week, and have been using it since then. So far the unit has been working very well, and for my non audiophile ear, it sound great. One thing I noticed immediately is that the background noise for Shanling H2 is very very quiet. Using my Fiio FH7, I can still pickup some background noise when using Sony NW-A105 and iBasso DX160, but on Shanling H2, the background is very very quiet.
