This DAC is getting ridiculously bad ass and thus more difficult for me to ignore. While I'm hoping to upgrade my analog significantly before my digital system comes back in this DAC is really starting to make me rethink that. There's just so many features being packed in here.
Definitely awaiting impressions once that update drops.
That was fast - I figured there would be some confusion. See, what the next firmware does is actually change the two 1/4" jacks to dual 3-pin XLR format through a proprietary FPGA liquid molding process.....
Oh wait, that's impossible. What it actually does is allow each headphone jack to act as a separate channel for balanced drive. Just like the Matrix Quattro Amp does, or the Chazz 2 tube amp. A special cable would be required - check my Chazz 2 link for an HD650 cable for $45, or else see HERE for more options including adapters that work with existing 4-pin XLR or dual 3-pin XLR. Or of course you could just contact your favorite cable manufacturer and have them make one for you.
This balanced mode essentially doubles the juice received by the headphones, as well as minimizing crosstalk from using a single TRS jack. I know people complained about it in the Matrix Quattro and thought they should have used XLR jacks. But since Resonessence is essentially retrofitting this upgrade, I find it brilliant and wouldn't mind working around it with a new cable or adapter.
