Since the introduction of satellite radio to the automobile market, I have been dying to get my feet wet. I love music -- especially in the comfort of my car. In the past two days I have experienced good XM radio and great XM radio. It started with an ad for Delphi Skyfi to have XM installed for about $200. I went to Circuit City. They recommended an Alpine FM Modulator and Tuner over SkyFi -- mainly for the fact that the SkyFi modulators were recently recalled. I spent $400 to have the Alpine FM Modulator added. But you know what? FM is FM no matter how you cut it. Yeah, the sound was slightly better than FM radio (very strong in fact), but you could hear the shrill highs in the music that often became overmodulated. Well, I went back to Circuit City this morning and had it all taken out. Instead, I bought a $380 Alpine 7894 head unit (I wanted MP3 playback capability), and had XM hardwired in my car. In addition, I had an old subwoofer boombox placed in my car with a brand new power amp. By the time I was done I spent a little over $1,000. It was worth it. The XM sounds absolutely incredible -- far more robust than the FM modulator with far greater dynamic range. In fact, you would be hard-pressed to not know it wasn't a CD playing. I love my XM. I guess by the money I spent today to upgrade, you can tell what an influence this new digital format had over me. If you want to get your feet wet, the Delphi SkyFi with FM Modulation may be an inxepensive option. I hear that some car receivers (mainly Kenwood) have inputs that you let you hardwire the SkyFi to it. Gregg Loewen can tell you more about that. I promise you, though, you'll like this XM radio so much that you won't want to stay with FM modulation forever. This is a forum full of stereo geeks like me who appreciate quality audio. If anyone else here has XM radio or even Sirrius satellite radio, I'd love to hear from you.
