Been testing out my new 16GB 5G Nano with my Shure SE530's.
Comparing to my Walkman A829 the walkman still has the edge in SQ but really not a lot in it to my ears.
Looks better than the previous one and the camera bit looks especially good against the silver Nano. I always thought the edges of the 4g Nano were too thin and easily damaged (especially noticeable last year if you saw them in the Apple store) but I think they've increased the gauge thickness slighty - looks much better.
The glossy surface really is nice. Screen look same brightness/colour quality but obviously bigger & wider. Same old crap earphones, not the clicker ones.
The touch wheel doesn't look to be over sensitive like the 4g.
I'm no sound quality expert but sounds just as good as my Walkman A829 really. Better for me actually because all the new Apples have zero background hiss while its very noticeable with the A829 with my Shures.
I think bass is a bit stronger than 4G nano. In fact, I'm sure it is as I thought the 4G was slightly weak compared to the Touch/3GS.
Its a keeper for me As good as anything I've heard before (but as I say, I'm no audiophile).
Can also confirm the multi-click remote works as before (I have the Shure iPhone adapter).
Radio is great. Even better than the one in my W960i and thats good. Live pause is really neat! Pause even works with remote. Better at getting a clean radio signal than my W960i next to it.
Video is fine for 640x480, much better than on my W960i. Can't see me using it much to be honest. Doesn't seem to be a way to see recorded ones in iTunes unless I'm missing something. Can pull them straight off the Nano in the DCIM folder.
My lad will be getting my Walkman.

Done some more extended listening tests back to back with my Walkman A829 on various tracks and the A829 does have the slight edge still but really not a lot in it and the integration with iTunes star ratings/play count plus cable remote operation means the Nano is the better choice for me.
