I get the whole "wire with gain" approach to the 789. With it in my chain, it's as close as I'll ever get to listening to the headphones interpreting the DAC and not much else. The amp sorta disappears. Possible endgame for the uncolored sound profile. Nicely job, THX and MD! I suppose the only other option for future changes is to swing in the other direction and go tube, but that's a whole can of worms I'm not ready to open... yet.
