I'll more than likely be buying one. Sick of the low quality audio phones output and love my current fios's sound quality. It should be $400 instead though.. $650 is a bit steep for a $90 music player, a $20 cpu, $30 screen, and a $2 micro USB slot($142). I feel like they think they're Apple at that price. It should have radio frequency output for that cost so I can highjack the stations I'm surrounded by.

Finally, they have delivered a device that looks as good as it sounds. Still a bit pricey and thick, but they are heading in the right direction.

I own a FiiO X3K (2nd Gen) and I am really, really impressed with it for only $299 and it offers DSD playback (.iso or DSF/DFF) along with 192/24 FLAC of course. Now while it may not the be the prettiest thing in the world or have the slickest controls, it sounds amazing and has great battery life. I think this device needs to be more in the $500 price range in order to justify it vs. other models in FiiO's lineup. I could buy two X3Ks along with two 32GB memory cards (maybe even 64GB, depending on sales) for the price of this unit without any SD card. That is a tough pill to swallow when you consider just how good the X3K is. I would love to have this device, but I just can't justify that price. There is nothing in it that should make it that expensive and I believe 12 months after release it will be $499, as it should have been from the start. If you want to start talking about the hardware inside and the screen as justification, look at NVIDIA's upcoming Shield Tablet 2 that is retailing at $299.99 and look at the hardware inside.
I do have one question. Can the player adjust the EQ on 192/24 and/or DSD?
