Satellite Radio Sound Quality

[Jeg45]

Greetings

I have always been disappointed with the quality of sound found in the HU-613 speaker system. I am contemplating adding XM Radio/Sirius satellite radio. Would the quality of the satellite radio through the HU-613 speaker system be significantly improved? Would adding the satellite radio system to the S-60 cause any physical damage that might interfere with future selling. Many thanks. Jeg...
