Hey all. I consider myself as someone that can tell the difference between good quality and bad quality sound. I pay a service to get 'high' quality streaming, but at the same time prefer to buy CD's of the the albums I like and rip to FLAC. I would say my "chain" is almost top of the line: PC -> iFI iUSB/iPurifier -> Bryston BDA-2 -> Bryston BHA-1 -> HD700 or DT990. So, I found this audio quality "test" online: https://www.npr.org/sections/therecord/2015/06/02/411473508/how-well-can-you-hear-audio-quality I can hardly hear the difference between any files, and I chose the 128bit samples a few times. Did anyone else do this test and do better? Usually, when I play a FLAC and 128bit file from my computer, the difference is crystal clear. Thoughts?
