Not sure if I'm posting in the right place, but am trying to find the best stream for the Norwegian national broadcaster "NRK" "culture" and classical channels: "NRK P2" and "NRK Alltid klassisk"

From the published URLs, the best streams I can find are (eg for P2):

http://lyd.nrk.no/nrk_radio_p2_mp3_h @ 192 kb/s


http://lyd.nrk.no/nrk_radio_p2_aac_h @ Sample Rate: 48.0 kHz (128 kb/s?)

Quite disappointing compared with the 320kb/s mp3 streams that most national broadcasters now provide.

Which of the alternatives is likely to be better?
