A Great Detailed Player.
This player only starts to shines after 70hrs of use. As explained in the player, you need to burn in the player for at least 200hrs. It do not sounds so good initially although it has the details but after 70hrs things gets better, mids gets better and vocal got sweeter.

Why this player is so bulky? Some might ask. Cause it probably have AMP built-in so it have proper power in the sounds and able to drive more power hungry IEM/Headphones.

For 3.5mm port the output is 60mw+60mw.
For 4.4mm balanced port output is 240mw+240mw.

As expected from SONY, the interface is easy to use, have some nice added functions and longer battery life than most or all of the same grade players on the market.

Some might think this player is expensive, but comparing to top of the line players, this player sound is comparable or even better than most. One of the most value for money and longest battery life around.

The WM1A replaced a well liked Sony ZX2. Yes, it absolutely is an improvement, even over the highly respected ZX2! More sound shaping options, and major hardware improvements.

No Compromise in Sound Quality
I got a rude shock when I first listened to it. The bass was muddy, mids were distant and treble has an annoying tizz. Thought I got a defective unit (my previous NW-ZX2 sounded good from the start) but the manual (and the Head-Fi thread) assured me that the best sound quality would only appear after 200+ hours of usage.

Burning in the new Walkman for more than a week was a painful wait, but worth it in the end. After 200 hours, the bass tightened up, punches with poise and precision, and the decay is just right, not too boomy. Mids are, as reported, sweeter and sounds natural. Timbre is accurate, with focus on musicality rather than detail and dryness. Best part is the treble tizz is completely gone. Amazing detail and smoothness, typical Sony house sound. The headstage is quite expansive, and imaging is precise. The more I listened to it the more immersed I was with the music.

In short it's an amazing Walkman worthy of Sony. Remember to burn it in to let the capacitors settle to their intended sound. Makes a world of difference!

TOTL sound, Feature packed and great battery life!
I love this player. I've owned many AK series and Fiio high end DAPs and I have to admit, the WM1A is the best priced player for extremely high value. I owned the WM1Z and I sold it when I listened to the WM1A.

My only request to sony is to bring out another update with a USB DAC function like the ZX300 has, and make the UI a bit more streamlined when showing album art for files that are not 'Hi-Res'. Added to my 24bit FLAC and DSF collection, I have a large collection of lossless WAV format files and it would be easier to navigate to them if the UI allowed album art for these files to show as well.

I bought NW-WM1A for my Sony Walkman collection since I owned my first generation of "S-Master" digital amplifier portable music player, NWZ-A846. As I knew from wikipedia, "Compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony and released in 1982. … The format is a two-channel 16-bit PCM encoding at a 44.1kHz sampling rate per channel." Because of her research and development, I respect her innovation and history as her brand that encourage me to own their products.
