Not going to happen Fetish Boy. People want freedom of choice.

What do you have against a hi-fi feed of the BBC World Service 24
hours a day?



XM's feed of BBCWS is hardly Hi-Fi. In many cases it sounds more
like a low bit MP3 with shaped response to filter out the higher levelss
of in spectrum aliasing noise. More refined than 5975, lower noise for
sure. And more detailed, perhaps.

Talk channels are more bandwidth limited than the music channels on
XM. Most aren't stereo, either.

XM is a lot of things, but one thing it's never going to be is Hi-fi.
Hi-fi is relative. Truth is, I like Sirius sound better, but XM
sounds higher fi than the HF feed, especially if S:N is a
consideration.

XM uses MPEG4, which synthesises the upper octave in the receiver.
