XM or Sirius

Actually I am quite pleased with the sound quality of XM service using a Polk tuner through a Benchmark DAC. Granted it is not nor do I think ever could be "CD quality" as claimed, but some formats (Jazz, Classical, Instrumental) sound pretty close. Format wise I think both are about the same from a music standpoint, X the differences like Stern or XM's version of anoying talk show hosts. I chose XM for home use due to the inclusion in my GM vehicle as I already had an account, and the fact that Polk was comming out with a home tuner with analog output to a DAC. Not sure if anyone has a similar tuner available for Sirius but I am sure if not they will soon.

I agree also with Mike above, sat is the way to go in cars if you don't mind non-audiophile sound. And for rg, tell your son to use the home antennae on his dash and use the mobile antennae at home, works MUCH better.
MMM

I have had both services and IMO Sirius is better because I mostly listen in a car or party situation, and Sirius plays more popular tracks.....for being in a car or at a party that is more pleasing, I also like Sirius more because of the DJ and music news, to me XM is more like Musac......sorta lifeless and they do dig alot deeper into music as far as unknown tracks, so if you like more variaty XM will work for you, but Sirius is more entertaining and plays more popular songs, as far as Audiophile quality it isnt gonna happen.....I much prefer the Music Choice channels on my TW cable for at home sound quality. So in short I think you should choose based on programming not quality, and I hope some info I gave helps.

either is like discovering music on the radio for the first time....no its not audiophile, but who cares...the comeday stations too are worth the price.

Jaybo, I completely agree. My wife gave me an XM receiver for Christmas and I had flashbacks to the best radio shows and formats I've listened to over the past 30 years. I'm more than a little bummed that they took the Prog/Jamband channel off the air but I can still get a fix online.
