Too bad they re still lossless, but hey! Awesomeeeeeeee
I challenge you to tell the difference between 320 kb/s MP3 and CD 16/44 in a blind (A/B/X) test of the same material, whetever it is, even on the best audio hardware in the world.
Hours of study of the latest papers on audio technology convinced me of this simple idea that mastering is the only factor that matters in the quality of an audio recording.
A redbook CD can be made to sound fantastic, no need for hi-rez SA-CD or DVD-A, our ear can't hear above 20khz and 16 bit is all the dynamic range we will ever need.
As for lossy, you can definitely hear a difference with 128kb/s MP3, but 320kb/s is as good as a CD will ever be - at least for our ears.
Care for good mastering, not the media !! A good master will sound good on just about anything; conversely, a bad master will sound bad even on a 24/192 hi-rez recording.
As I already said regarding DIME, 24/48 FLAC files are overkill for a live concert; of course they are fine, but a 320kb/s MP3 will just sound identical, while taking only a 10th of its size and downloading time !
