I'd simply use squeezebox radio to keep it simple cuz most of internet radio broadcasts are luckily 128kbps.
Interesting about Swiss Jazz! What artists have you been listening too?
So far I've mostly been listening to German Jazz (Jazz-Baltica Hamburg festivals involving musicians from all over Europe and US). Also got stock for a while and cant' get out from Nils Petter Molvaer(Netherlands trumpeteer) and his crowd. Also from Holland: Jasper Van't Hoff, Jan Garbarek, Jan Akkerman(Focus band), Finland: Pekka Pohjola(just found out that he died in 2008...) Sucks that none knew, but he'll probably be recognized in couple of decades after his death as one of the greatest musicians and composers -- a true maestro.
All of it can be heard on terrible 96kbps broadcast from
