Yes, I listened to couple of stations on NAB in Las Vegas. The one I listened most, played 80s and had 3 channels - main music program, additional music program and a talk program. Like I already said, I would never called any of these "full-quality". They all (the talk channel being the worst) have apparent artifacts, mainly the grainy, metallic highs from SBR coding.
But this is nothing new... I have several Opticodec streams that run the latest aacPlus codec (which is very similar, if not the same, to IBOC/Ibuqity codec) which exhibit the same artifacts. Don't get me wrong, this is a HUGE improvement over phasey and flangy codecs of previous generations, but unless it's 96kbps (or at least 64kbps) the artifacts are quite noticeable for me to agree with "full-quality" claim.
