Michael,
Congratulations on clearing a challenging hurdle.
I've got a question for you regarding your constant references to "loudness", though. I understand this is an amplifier, but do you really think it makes sense to refer to loudness over, say, refinement? After all, anyone could make a loud product...refined, that's a different story. Also, I doubt anyone really intends to encourage people who haven't already damaged their hearing to listen at loud levels. For me, half of the benefit of an amp is being able to listen at lower levels while still being able to discern all of the available "information".
I'd argue what you're bringing to the table is a combination of refinement, power, versatility, and utility. And I don't think you focus enough on the ability to play high-resolution files out of iDevices. As far as I know, this is the only transportable/portable DAC/amp combo that will be able to play 24/96 out of iDevices without a CCK. I doubt I need to sell you on how significant this achievement will be.
I feel as if many manufacturers shy away from touting the benefits of solidly-mastered hi-res music simply because most people currently have primarily 16/44.1 files. With all of the advances with DACs, amps, and headphones, not to mention the ever-decreasing cost of storage, it seems silly not to lead people to hi-def music in much the same way as was done with video. Why pay for a 1080P television if you're going to stick with standard definition cable and DVD?
Right now, it seems you'll have the device to beat...at a very reasonable price, I might add. Within reason, the only ways to better it will be to decrease the size and/or integrate a DAP. Keep up the great work!
