Definitely check between the different listening options they may give you. Just with headphones on, there was a major difference between what some of them offered.

Jazz FM 91.1 Toronto. Available on itunes as well.

Jazz Wyoming 90.1 broadcasts at 256 kbps. Mostly modern-day, but happily not too smooth-jazz.

KSDS, aka Jazz 88.3 in San Diego, http://www.jazz88.org/.

24x7 'real' jazz, no commercials.

WONC Naperville, IL. 10p-12a Vintage Rock - The best from 1964 - 1974, they do it right. This is vintage rock not the same ol' lame classic rock.

If WFMT in Chicago is available I would check it out.

I listen WCRB in Boston (my home town) for classical and I like the BBC stations for rock.
