Hi, I'm new here, but "lurking" for some time, and as an audiophile, I really enjoy this forum.
So today I went to the Ginza Sony Store in Tokyo and tested the new NW-ZX300, using the balanced output. They had two demo models, black and silver (both 64 GB). Here are a few thoughts.
1. Design. NW-ZX300 is an incredibly well-crafted little device, feels very good in the palm of your hand, very light without appearing cheap or plasticky (like the old Apple nano). You really feel it's a quality product, sleek, gorgeous, and sexy--a miniature version of the NW-ZX2! It almost feels like an oversized luxury lighter, and at first glance might even be mistaken for one! The matte display is new, and that also is something to be impressed with. For one, you don't need to worry about fingerprint smudges anymore, and for another, it really feels nice too!
2. Sound quality. I own both the ZX100 and WM-NW1A. The new NW-ZX300 sounds a LOT better than the former, while it is still slightly inferior to the WM-NW1A in terms of sound quality. But that's of course to be expected. The difference, mind you, is very minor, but noticeable for all that, if you're an audiophile like myself. The natural clarity and impact is slightly lacking, but again, it's a minor issue. It still sounds better than 98% of audio players out there!
3. Overall impression. This is another wonderful quality product from Sony, and I personally will definitely get it (I prefer the black one). The number one advantage is its portability, no question, combined with its top-notch sound quality, even if it doesn't quite reach the heights of the WM series. And while on the go, honestly, I bet many of us don't need a WM-NW1A or WM-NW1Z like sound quality anyway!
