This is my first post and I should state right from the get-go that I do not yet understand the many ways an audio stream can be "rated" for fidelity. I have BBC Radio 3 (High) on iTunes with 320 kbps bit rate and 32 kHz sample rate. Does this constitute a high-quality stream? By comparison, France Musique in iTunes shows 128/44.1. Is this inferior to Radio 3? Thanks! Greg
