Those thinking of upgrading from the Z1060/70 to either F887/ZX1 should give it some hefty consideration first, why do you want to upgrade should be the most important consideration... if you love the detailed warmth of the WM-Z and are not bothered about Hi-Res stick with what you got as you might not like the subtleties in the change of SQ in relation to the ZX1.
The ZX1 is the superior DAP in almost every aspect apart from one, it has no real warmth dealing with certain genres that have been 'time-locked' production wise from another era, these genres love warmth imo and without it they can leave you feeling a bit left out(?), cold if you will as the extra detail actually has a numbing effect... for me the ZX1 is a upgrade that I'm 99.9% happy with, I just hope Sony can take care of that 0.1% by adding a touch of warmth at some point.
This might answer the 'why is Turok selling his ZX1' question... hopefully he'll hang fire and see if a firmware update helps, I'll remind him of how the last firmware update for the Z1070 went when Sony rushed out a correction restoring the bass... I had visions of Sony employees falling on their samurai's in shame over that one for getting it wrong.
