Will mention it to Seagate. I was looking to get a new tablet and considered the Kindle Fire HDX tablet. Was curious on the built in DAC + opamp that Amazon is using. Wanted to to see what the output impedance was, the various mA rating at a number of different headphone impedance ratings, voltage output swing possible, etc. As expected, Amazon wasn’t willing to divulge the info. I did ask them if they would implement DPS plugin to improve sound quality while watching movies or listening music. The customer rep said they would pass the request to Amazon’s engineering department. Hopefully you’ll hear from them.
