Thanks for the feedback.
I am really only going to use it for home theater applications and don't want anything for the car.
As for Sirius vs. XM, I personally like the music selections and more comercial free broadcasting on Sirius better, thats why I was opting for Kenwood home tuner. I also got the impression that although the sound quality on XM was slightly better (according to other posts) than Sirius, I also didn't like the tuner options from the XM end of things, they seem rather tiny and visually unpleasant in contrast to my home set-up.
But I am taking all of these responses into consideration and appreciate the feedback.
