I have a 5.1 setup so I had 5.1 down mix enabled, but after setting it to 7.1 I noticed quite a difference, even when listening to plain stereo, the sound stage opened up, vocals stood out more, and I could hear nuances in the music which I've never heard before.
You could also try under the video setup options, set the output resolution to source direct, and under hdmi options set color space to rgb video level, I think this may have made a difference but I'm not sure, but definitely try disengaging down mix.
I have done intensive testings in that regard, I recently bought a Pioneer LX08 BDP for testing purposes (same as LX71 and close enough to the LX91 and 09FD I teted too).
The 7.1 speaker downmix is NOT the right mode.
I have managed to have the cambridge sound almost like the Pioneers, which sounded better prior the right adjustments in the cambridge.
My setup is stereo only and I noticed these huge differences in the downmix modes on stereo signals too.
The right settings are these ones :
- HDMI color space to auto on both, deep color off
- set it to PAL if you have a PAL compatible TV, NTSC is off on mine (but maybe on the US models it's the opposite, I don't know). Don't use multi system.
- 1080p/24 to forced
- resolution to source direct
- HDMI audio to bitstream
- speakers settings to 5.1, subwoofer on (even if you don't use one), and all speakers to large
If you use analog audio, use the Front Left/right terminals for stereo not the dedicated stereo ones.
HDMI Audio sound like crap (really), so if you use digital, use the optical out, you will loose the HD formats, but still have the DTS core or DD compatibility track which is about as good, and the gain in SQ is pretty substantial, pretty much the best SQ out of the unit. Analog has a little more punch, but soundstage is worse.
All these settings have audible effects on analog AND digital audio.
Something isn't right in the mediatek board, and I'm glad to have been able to compare the cambridge to other good sounding players (same DACs in the pioneers), to get the best out of it.
Edit : I just tested with digital coax, and it's slightly better than optical, I couldn't try before I was waiting for my Mogami cable to be delivered.
