There seems to be a large demand for a device like the Pono player, which I'm sure is great, but is not very practical - nobody needs to carry a separate player when they already have a phone with plenty of memory. Although I only listen to lossless files at home, I am certain that their benefit over regular 320 kbps mp3s on a noisy street are nonexistent. What the audiophile consumer needs is a good portable amp/DAC that would drive even high impedance headphones and that's what I like about your product.

Speaking of audiophile consumers, I tink that it would be great if you could offer two separate verisions of your product: 1. The full version that you have just released. 2. A second version, specifically aimed at people who only care about HiFi sound coming through their headphones. I don't really care about the speakers as they will never replace a proper audio system. To me they are just taking up space and it would be great if I could buy the rest of the technology in a smaller package.

One more question - I guess you'll offer Amp with a separate music player iOS app. It will probably run a few hearing tests in a quiet environment and that's how it will adopt to one's hearing. If so, will it also support various headphones? Not having to EQ the Beyerdynamic DT1350 and other cans with weird frequency response would be very helpful and will make your app bring the best out of any pair of headphones.
