Binh,
Thanks for the reply, as far as what's inside the unit...been discussing that in the other thread I made about identifying the player.
http://mympxplayer.org/viewtopic.php?p=60481
I've got pictures of the internals and chip numbers. I have been unsuccessful in locating which chip the DAC is...the number of chips I can see don't add up...all I can see is the NAND, SDRAM, RK2706, JST touch screen, LN4890 and what we suspect is a 5800C FM chip. I can't account for a DAC chip anywhere.
I wish I knew..it's a nice sounding player. Good 'phones help, I wish I had the adapter so I could try my Sennheisers on it...but I've had my Bose since Christams and have adjusted to thier tonal properties so the senny's would sound like garbage.
As far as where I got the player..I bought it from acp_seller store on ebay.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170330383953 is a link to my particular player. The only other full-featured mp5 player he had was the same thing in a 4 gig. However, I bought one...it arrived safely and didn't have hacked capacity (otherwise my flac copy of a vinyl rip of The White Album would of been corrupted).
