Now for the not-so-good news. I have a Seagate NAS 200 configured as a music server. My old WD TV Live streamer did not have an issue streaming audio from this box, but the OPPO does. This is not an issue with the OPPO but rather that NAS. The Seagate uses what is called “mimiDLNA” which is not DLNA certified. The result is that the OPPO “sees” the server and the server “recognizes” the OPPO (login and password are matched appropriately and trying to access shares not granted permission from this login are rejected), but when viewing the FLAC files in the MUSIC folder, the list is never displayed (LOADING icon never finishes). Other friends with DLNA-compliant servers do not have this issue (a recent email from OPPO's outstanding service department has assured me that they will address this in a future firmware release and not to sell my NAS).
For now, I have a backup USB drive plugged into the back of the OPPO from which I can stream any of these FLAC files with no problem and amazing clarity. The high-res 24-96 and 24-192 files are stellar and dearly demonstrate the audible differences between the three formats (from 16-44). This DLNA issue was raised by OPPO owners even before I bought the player so I was aware of my chances at making this work. As of today, I have not found a solution to this issue so it appears that I must go for a very different NAS (other than the Seagate BlackArmor series anyway).
Also, see the simple FRED diode modification to the BDP-105 here.
Yours for higher fidelity,
