There’s another new Sony Walkman, the NW-ZX700. It’s 104,500 yen ($818) in Japan, and while that sounds like a lot for a portable music player, it’s actually a relative bargain compared to the “Signature Series” NW-WM1ZM2, which goes for an eye-popping $3,700 thanks to audiophile hocus-pocus like a “gold plated, oxygen-free, copper body.” Anyway, back to this $800 model. Unlike regular phone equipment, this has a proper audio amplifier with big, beefy capacitors to power the analog audio output. That makes it much bigger than the A300, at 72.6×132 mm and a whopping 17 mm thick. It also has two audio outs: a standard 3.5 mm headphone jack and a 4.4 mm “balanced” audio jack, which is used by some high-end audio equipment. I’m sure Sony has a wonderful headphone collection to match. […] Both this and the A300 use the S-Master HX digital amplifier chip, which supports Sony’s high-resolution “NativeDSD” audio format, which is also used on Super Audio CDs. If you’re some kind of heathen that is just streaming 128kb Spotify, Sony’s “DSEE Ultimate” feature dubiously claims to be able to “upscale” your music with AI. There’s also a “Vinyl Processor” that will add record player noises to your audio for an “authentic listening experience.”
