I only plan to make a few of these, unless I get arm bent by people. I am burning in a pair right now. The work to mod them was much harder than the 780 mod, and I used more material for the internal work. They are quite different than the 780s. Still getting some impressions, but right off the bat they are more mello, smoother and a bit easier on the ear than the 780s. Very nice though. I know there is a pretty substantial burn in so I am going to hold on the report.
