Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
I think you'll find that this is not new.
The last gen Pioneer players (the DV610 and possibly
DV410) had this feature already.
You can 'rip' audio tracks from your CD to MP3 with a USB stick and select the quality of recording.

Their even older DV600 had a very handy ability to play Audio & Divx files straight off of a USB stick (and I know people who had a hard-drive running from it for movies and music)
....and yes, my experience of the 6 series is that they are superb
DVD, SACD & DVD-Audio players.
The audio is it's strong-point, especially the analogue outputs - 24bit DACs and burr browns at this price are a very good deal.
i was a proud owner of the dv-400 for a year til i got a PS3. besides it being a little crushy with dark detail, this is the next best thing under an oppo, IMHO. that faroujda upscaler does a hell of a job...
