I just bought a 2012 Mini with an HK system. Returned from my first road trip of about 1200 miles feeling somewhat dissatisfied in general and very dissatisfied with the Sirius sound quality. My perception of the sound is that it has too much "reverb", an echo-like quality, which translates into it sounding tinny to me. Has anyone else perceived similar sounds? I had a 2006 Mini prior to this one and it sounded fine.
