Hi all,
    Been lurking for years.  I searched but could not find anything so maybe you can point me or provide insight.   If I were to wish to do some critical listening (192 kpbs vs CD), I am wondering if I'd be better served by headphones or speakers?   I know the room is less than perfect but really am wondering which is a better plan (or maybe neither will have the build quality to reveal anything?).  My system is  Yamaha RX-A4A, Goldenear Triton 3+,  and grado SR-60.  (Soon to get a Hypex amp from Buckey but not yet!).   Also it'll be served by a Bluesound Nano sending ripped FLAC files and MP3's saved to an external disc. 
    Is this system up to resolving the music enough to discern?  What to use?  Speakers or headphones in general and in my case?
THANKS for any thoughts!
