Since I spend a lot of time studying (law school ), I end up spending a lot of time listening to internet radio. However, I have found that even the "high quality" (128kbs I believe) setting on Pandora leaves audible compression artifacts when I'm using my studio headphones (audio technica ATH-M50). I can't hear said artifacts with stock earbuds or my low end IEMs, but I would prefer not to have to choose between low-fi headphones or digital artifacts. I'm almost always in wifi range around here, so 3g bandwidth is not a limitation. Any suggestions? One qualification: the service needs to be more than just popular music. I listen classical or jazz pretty much exclusively when studying. I don't mind paid as long as it's reasonably priced. Also, anybody know why they can't make Pandora One work over wifi with the iphone? I understand 3g bandwidth limitations, but seems like there should be no problems with a wifi connection.
