I love XM! I can't tell you how many new artists, and new discs I have found just listening to XM. It doesn't sound great. It sounds much better than FM, but it's still compressed, and it has a brick wall at close to 14K.
The reason I got it is for the live stuff. Telluride Bluegrass festival was broadcasted last weekend, and for 8 hours+ a day, I was able to attend that from my listeing room. Live events all the time, and exclusives like Janes Addiction in the studio talking about, and playing their new disc. . .
It's not about whether it sounds great, it's about hearing things you can't hear elsewhere, and also finding new stuff to buy in a better format. . .
If you do get XM, get the Delphi. I have owned the Delphi, and the Sony, and they are WORLD'S APART in sound quality! And usability. . . Sound on the Sony sucks BAD, and it's got a fan. .
