I find the Linn classical station a bit off-putting because it seems to consist of broadcasts of short snippets (possibly for Linn dealers to demo their gear?). Dunno about Linn's other stations. AVRO Netherlands does 256 kb/s, but the music often borders on Muzak. WDR3, Bonn, Germany is only 128 kb/s, but the music is good and I enjoy it for background listening. Most of my internet radio listening is BBC World Service or Radio Nederland. Austin's terrestrial classical station, KMFA, has a horrible bitrate (32?), and I prefer to listen to it via my tuner.
All that said, I hope and expect that there will be better musical and other programming options in the future, though I notice that Radio Nederland is watering down their offerings with a Europe-wide consortium of programming.
