Cambridge Audio bd-640 blu-ray player

Has anyone purchased this player; and if so, what are your thoughts thus far? Tks.
I read somewhere that it is a re-badged Oppo.
I have searched the 'net for reviews but thus far I have not been able to find a single review. I would very much like to know if the sound quality of the bd640 is better than the Oppo bd-83/bd-83se. I will continue my search and if I find any I will list the source in this thread.
Depending on your budget, you may want to look
at the Denon 3800bdci on sell at listen up dot com.

Fantastic on Blu Ray, DVD & redbook cd.

My last player!
