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.
Sometimes with hilarious results. On the ABC Talk channel last
weekend, the top end synthesized material lagged the baseband by enough
to sound like a cheap slap. Rebooted to clear it up. MP4 or not, a lot
of the talk channels, BBCWS included sound pretty ratty.
I"ve only heard a couple of Sirius receivers. And those in pretty
high noise environs, so an evaluation was pretty meaningless. I'm
getting one later this week, though for evaluation. I'm interested to
hear the differences.
Truthfully, I'd rather hear HF on a well tuned Hammarlund.
