@raoultrifan - sorry man, haven't had time to do an A/B comparison of the Essence with the Burson's. I'll try get to that and report.
I finally received my 7812/7912/7805 from the US, so I'll be looking at replacing stock at some point.
I have received my HD800's (after some stupid import issues). Noticeably better than the HD650's I was using prior. Very impressed.
I actually have a balanced cable that came with it but am currently using it with the normal front 1/4in jack
This brings me to the question: has anyone driven balanced headphones direct, with the balanced outputs on the rear of the unit? Is it doable?
