upgraded fine-tuned capacitors and a FTCAP3 (high-polymer capacitor) and a large solid high polymer capacitor which offers large capacitance and low resistance. While an OFC (Oxygen-Free Copper) milled block covering the digital block
sound, further enhanced by new high-quality sound lead free solder
Just like the latest Signature Walkman model, both models apply a reflow solder containing gold, whose effect is significant in the overall improved sound localization and wider sound space.
Wow, really laying a thick layer of bullshit there aren't they?
The NW-ZX707 and the NW-A306 both use Edge-AI (Artificial Intelligence), DSEE Ultimate (Digital Sound Enhancement Engine) which upscales compressed digital music files in real time. The evolving algorithm now delivers even greater benefits for CD-quality (16 bit 44.1/48 kHz) lossless codec audio. Restoring acoustic subtleties and dynamic range provides a richer, more complete listening experience.
Just what any audiophile would want, AI "enhanced" music instead of original and pristine source material...
On the contrary, DAPs have become more popular after phones decided to forego wired audio.
Nope. These are digital audio players that can handle things your cellphone cannot. Unless you are carying around a portable DAC/AMP combo that can cost hundreds to a grand and plugging your phone into that. These are completely different animals.
Just as your airpods cannot complete with 150-300 buck wired headphones let alone the ones that start at a thousand and go up.
How much storage space does this DAP have? It certainly has some, but from the marketing not mentioning it once and talking about wifi and download media it's meant to stream... right, great quality for sure.
First you dont drain the battery of your phone with a DAP which i have found was a bit of a problem when i used my phone to listen to music it drained the battery too fast and yes i know i could fix that with a battery bank but that was not the point
But you get an extra device to charge, carry and take care off. And as streaming has become the norm, in all likelihood you'll be using your phone as an hotspot for this device draining both batteries even more.
