How to improve XM Radio audio quality?

8oclock- If you want better sound quality listen to FM (sorry, I couldn't resist that). Both satellite radio services transmit highly compressed PCM data which, when uncompressed, is inferior to CD quality (or FM) sound. If your XM tuner has a digital output you could try an outboard DAC, otherwise you’re stuck with what you have (garbage in garbage out).

XM quality is much better than any FM reception.

FM CAN be better than sattelite radio. Unfortunately, here in Houston, it is not. Leaving aside the programming issues (XM is FAR superior), the one classical station here (NPR) must use a compressor/expander because that is what I hear, not to mention the background noise that seems to be inherit in FM. I've tried the yagi/rotator/high-end tuner route. Sorry, no cigars.

The best way to improove XM's sound is to scrap half of the useless channels, and wait they are adding more! great right???? WRONG the more channels the more the signal loss, and untill they change some technology, the more they add may seem good on the surface, but those 75 channels you never listen too and never will, suck the life blood out of all channels

Without being propelled up to XM's satalite with a bagfull of audiophile jewlery and a digital geek or two, the most cost effective way to de-grundge, re-liquify and bore a hole in the soundstage is a "tube buffer" added at the outputs of XM's digit flatulator. If ever there was a calling for the old Musical Fidelity "X" Can's, Satalite radio is it. It is amazing what a couple of small tubes in a beer can will do for modern technology.
