The picture comes from one of the headphone fan in China(www.erji.net).   This is a Japanese amp which can drive both electrostatic and dynamic headphone together.   http://www.ishinolab.com/modules/doc_merchandise/original/masters/sx-3000bd.html     Sounds good?  Anyone try this amp...

Hi guys, I just got my TAKET H2+ and I tried to use HIFIMAN HE-adapter to connect this phone with my Teac speaker amp(60 watt per channel) But I found it still cannot run it loud enough. I just wondering are there some output restrictions from HE-adapter or just the amp not powerful enough?
