Not really. I prefer my Jap A867 over both the X1060 & Z1070 that I have. My favorite overall is either the A & F. However, it is a sonic preference thing than anything else b/c I also think the Z is also superior sounding to the X. Your A must be the Euro version, isn't it? This is based on pairing these DAPs with my JH13pro only.
Nope, NW-847 from Japan. Bought it at Bic Camera myself. They may have refined it by the 867, but the X1060 beats the A847 in SQ hands down. I skipped getting a new Sony DAP until the Z1070.
The A & F win on size for me, but neither are better than their "bigger" counterparts with any set of cans or IEMs I've used. The smaller DAPs for whatever reason even with S-Master seem to not be as balanced across the sonic spectrum and lose a bit of gravitas to the sound. It's more striking from the X to the A in my case and I think I noted that here a few years back when I made the switch.
