Hoping the DX90 drops, I've been hearing amazing things about it. Apparently it blows the x3 and dx50 out of the water and is better than the X5 as well!
J.J.CI'm hoping for that one too! I have the X3 and while the sound is fine, I'm not a huge fan of the UI. It's also developed a couple quirks where it will occasionally shut off randomly in the middle of a song. It's never a particular song and I've never been able to get it to repeat the error intentionally.
