I have a serious question on this topic: Does your internet provider matter, as far a the quality of sound. I am not claiming it does not exist, but I am skeptical, because I have never heard streamed music sound as good as a good CD on my system, or significantly better than my KT-917 or B&K TS 108 tuners.
CD vs streaming is somewhat of it's own hotly debated topic. Several people have compared streamers vs transports into the same DACs. I think it's something that's best to try and decide for yourself. But your ISP *shouldn't* matter as long as you are getting appropriate bandwidth.
