What's the output voltage and impedance? Crosstalk? Noise? THD? Dynamic range? If I plug to charge via USB while I'm playing it, will it isolate the noisy power line? You're trying to sell something "audiophile" without mentioning any of this? Really?
He makes a big deal about 192kHz audio. If you're targeting human ears, this is just a waste of space. I'd say the perfect format would be 48kHz/24bit. 48kHz to have plenty of room for a nice frequency cutoff, and 24-bit for music with a high dynamic range, like film scores and orchestral.
Not to mention, 3.5mm TRS jacks.
Good sets of headphones from the big audiophile companies (e.g., Grado) have 1/4" TRS jacks. The "consumer" level Grados (SR-60i, SR-80i) have 3.5mm TRS jacks, and a 1/4"-to-3.5mm adapter (and we're still talking about headphones costing less than the Beats crap you can get at any store). The next step up, the SR-125i, is still below the price of the Beats crap, but only 1/4" TRS. (Great, did I just mention audiophile class headphones costing less than consumer level crap? Sure you can get $2000 Grados, but damn the low end is well priced).
Next - it has line level analog outputs. But again, 3.5mm TRS?! At a minimum, you'd want traditional RCA jacks for linelevel (better channel isolation than TRS).
And above all, you'd think it would have true audiophile features like XLR balanced (differential) outputs - less noise than line level.
USB isolation is interesting, because well, USB chargers are crap. They can emit tons of noise - so much so that poor quality ones disable touchscreens on phones from all the noise.
And some other problems - they don't have a list of what music they have - I mean, there's a few soundtracks I'd love to have in higher quality, but I can't browse what they have because their site isn't up yet. So far, all I see is a bunch of music that I'm honestly not interested in.
And face it - the music audiophiles listen to is classical (or for me, soundtrack scores, which are orchestral). I better expect some dynamic range to the thing. Classical music is hard to reproduce - you've got delicate sounds of instruments mixed in with others. A common place rock or pop song well, high res audio doesn't really improve things at all.
