System not playing higher resolution flac files

System 

 Bryston BDP 2 streamer /transport
Coax rca connection 
Audio Note dac 3.1
Bryston stock interface. 

I recently changed to the bdp 2 as my source. I could no be happier with the sound upgrade over my previous source which was a laptop to dac with a profigy analogue digital converter in between.

I have now come accross a few flac files that will not play. They show they are playing on the interface but not coming out of the bdp2. I noticed these are files with a bitrate of 4000+kpbs range. They played fine on my previous setup. Flac files lower than that kbps play fine.

I have no idea why this is happening. Hopefully some one has an answer.

Thanks in advance for any help
