I solved all my problems with FW3.0!
…I reverted to FW2.05
Today I had to reset my player on EVERY album I tried and I had enough.
I have tried 3.0 and 2.14 for the last few weeks and both turned my X3 into a self-inflicting torture device; crash crash crash crash!
So…now back to 2.05 and all files play, commands are sluggish again (no prob for me), and I have gapless back without the crashes with 2.1. yippee.
I also have to add that using a pair of Ortofon E-Q5's the X3 sounds best to my ears in it's early 2.05 state - the 3.0 was pretty light on the bass and 2.14 a little bright on my ears…now, I am back in flavour country and will be resisting throwing my X3 from the window of my early bus commute. This should never have to be so frustrating.
Good luck to all.
