Thanks for the great review! Mine should arrive with the post tomorrow.

NICE!!

Thaks for the review. Do you think it will drive Yamaha-yh100?

I really really enjoy mine!  For a future revision, it would be nice if it could auto shut-down if no signal has been received for quite a while.  It's not a product flaw, but a user flaw, that I can't seem to remember to turn off my portable hardware!

bwah hiss with low impedance >.>, guess I'm stuck with the pb2 for a bit longer, still nice review! I love how it's offering balanced outs on a portable dac/amp out

I was wondering if you have had a chance to hear the version of the HiFi-M8 with the ($99) IEM Mod that is supposed to lower the OI even more so that there will not be audible hissing with low impedance IEMs?
