Caveat: self-identifying audiophile here, happy to admit I've spent way too much money for very little gain.
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.
How about some features anyone can enjoy, like support for ReplayGain and gapless playback? Maybe make your store highlight music with a high dynamic range instead of offering a 24-bit copy of something with 8 bits of range and frequencies we can't hear?
I would absolutely love to have a compact, objectively transparent player that I can bring with me to the office or anywhere else. I just can't help feeling this won't be it. Too jaded?
