My NW-Z1070 arrived from Japan today. Not bad time. Ordered last Thursday, mailed Saturday via EMS and arrived in Brisbane at work today.
Following the helpful info on this forum, setup to English was easy, and I was up and running in no time. Synced my music across via my Robocopy batch file to the already existing music folder on the Z. Took a while to update the database. Noticed a couple album art images missing. Will sort that out later. I played around with gingerbread for an hour or so, but comparing to my international Z which I updated to ICS as soon as I purchased it, I very quickly decided to update the 64 Z as well. That done, here's a few observations...
- Clearly the space is the main advantage. Just plain dumb that in a DAP this level there is no microSD.
- Very easy to change the default keyboard to a Qwerty. There's one installed. No need for a third party one.
- The provided NC earphones are definitely better than the international ones and pretty damn good actually. Instantly comfortable. The hybrid tips are very kind on your canals. Pretty easy to listen for hours.
- Listening to them right now, really quite nice. Maybe a little too forward in the upper mids and treble with just a hint of sibilance on some tracks I've listened to and may not be fast enough to keep up with some busy music. Noticed they got pretty messy on Coldplay's Mylo Xyloto. Hurts Like Heaven challenges any earphone or headphone. Just A/Bd them to my W4Rs, and they have no trouble keeping up. And the snare isn't bashing your ears quite like the Sony's.
- Bass quality and quantity should suit all except the biggest bass fans. Tried them on a standard test track of Vaughn Williams "Landscape" from his Symphony No7, the Sinfonia Antarctica. At around 7mins 30secs, there's a very low frequency section that must be near the threshold of many phones because it is often almost inaudible. The Sony's had no problem with it.
- Tried out the noise cancelling, works pretty well in some home testing. Will give them a go on a plane flight Friday.
- There is definitely more volume available on the 64 WM-Z. But you should not damage your ears unless you have very low impedance phones and careless.
- Sound quality is as expected. With the phones I use as a reference, my HD25-IIs, the SQ is indistinguishable from the iNternational Z. I know some say that like many Japanese devices they have a bit more treble but gee it must be slight as I am having trouble picking it. But sound quality is very satisfying.
All in all, I'm very happy I took the plunge. Sure the F is newer and snappier according to an earlier post today, but I like form factor of the Z. Just the right size to carry without being cumbersome and able to use its screen for much more than music alone.
Happy to answer any specific questions anyone might have so long as it doesn't involve test gear which I don't have any of.
