It sounds absolutely perfectly the same, there is no difference. When starting the App it says it detected my DAC and i am able to play Hi-Res Audio. Why would that be?Ĭlick to expand.I just tested it on my ZX507 with the Free UAPP Trial. When running the WM1A/Z player app on something like the A55, the sound gets greatly improved. On the Walkman OS, the UI you're seeing is basically a Linux executable, a player app. How could audio from the Walkman player app sound different? USB Audio Player Pro managed to send audio via the same path as the Walkman player app, which is the only way to play bit-perfect audio, and guess what? The sound signature is not the same when playing bit-perfect audio from UAPP, in comparison to the Walkman player app. The one that is being used by all other apps downsamples audio to 16/48 or upsamples it to 32/192, depending on a setting you can toggle. This is, of course, coming from your fixed view that Sony doesn't do sound processing in software to achieve their sound signature in these players (of course, the hardware has a role, but not as huge as they want us to think).Įven on something like ZX507 - internally it has two paths for audio, one that is used by the Walkman player app, and another that's being used by all other apps. With an frequency response analysis, and analysis of the delay, post-echo, pre-echo and so on and we should have an complete picture of what exactly changes. So with a simple headphone measurement rig it should be pretty easy to say what exactly changes between firmware upgrades and then we could create a table and say "You want more soundstage, use FW Version X, you want more that, use firmware version Y" and so on. Its impossible that the outcome of an played back song is identical when any of the characteristics of the DAP change. You loose some things, you win some things (for example impact decreases the more you increase the delay because you're adding an pre-echo).Īnd in the end you could also just play a song, record the outcome, change the firmware and record the outcome again and do an analysing with audacity. And increasing the sound stage by modifying the delay is not an improvement, its an change. I don't know if the S-Master HX does support it (AKM DACs do), but if that would be the case, that can be measured too with an simple delay test. The only way to modify the sound stage without modifying the frequency response is by adjusting the delay of the DAC. So there should be an difference in the FR. The lowest energy x-ray frequencies are like 1,000 to 10,000 eV, almost harmless but its still one to ten million times more energy than a radar wave, then how harmful can a cellphone wave be? Not only does it lack the required energy but it also has much too long wavelength to interact with atoms.Click to expand.That's true, but most people notice differences in bass and treble too. Even so we can survive taking an X-ray now and then. But a "hard" x-ray can have a photon energy of 10 million eV, or more! These are dangerous, the short wavelengths, shorter then the size of an atom, make them able to interact with atoms, they can knock off electrons in atoms in a cells DNA which can result in cancer.īut see the energy level it needs to do this? its F'ing TEN BILLION TIMES more energy than a radar wave, which are more powerful than cellphone radio waves. Radar has a photon energy of like 0.0001 eV (electron volts) or even less than that. No need for a formula, but basically you can say that higher frequency waves has higher energy, and i mean a lot higher. Another way to show it is to look at the photon energy of electromagnetic waves.
