Yamaha RXV679 - muddy sounding dialogue

Hi all,
I recently acquired a Yamaha RX-V679. I've paired it with Martin Logan MLT-2 5.1 system. Once setup, I ran YPAO . What I am finding is VERY muddy dialogue when watching streaming television. In order to hear the dialogue, I have to turn the volume up fairly high. I have tried to manually configure the speaker setup, audio levels, and surround programs but the problem still persists. I have the center channel level turned almost to max and it is okay, but still not right. I've read on forums that this is a fairly common occurrence with Yamaha receivers but I haven't seen a resolution.

Has anyone experienced this and how did you fix it? I love the features of the 679 but its poor performance with dialogue is annoying.

Just needs a little EQ.

If you have the speaker inside a cabinet, it is artificially boosting the bass. Go into the EQ menu for the center channel and cut a few dB in the 100-200 Hz range.

Alternately, if not in a cabinet you could be lacking presence. In the same menu do a slight boost in the 2-4 kHz range.

"A nice mid-fi system," according to an audiophile acquaintance.
