I have a Denon 1912 reciever with a pair of Martin Logan motionflow 12's and when I'm playing anything higher than 16/44.1 it starts to sound really bad. Ear piercing highs, mids are all over the place.
Is the built-in DAC the problem? Speakers are 4ohms, reciever is only rated up to 6ohms. Using 16 gauge wire atm, going to switch to 10 gauge soon.
Have had them for 3yrs now, started getting into high-res music awhile back. Sounds fine when watching movies in DTS-HD though.
