I have the H/K SB 30 and absolutely love it. Subwoofer is better than my Onkyo HTIB sub. I'm not sure Klipsch had that soundbar last spring, otherwise I would have checked that out too. I doubt you'll go wrong with either.
Looking forward to your review. I have been researching the Klipsch Icon SB1 but not many reviews as it is still fairly new. I would be curious if you had a chance to audition both the Icon SB1 along with the Klipsch HD SB3. If so what where your impressions of the HD-SB3s little brother. Other than the additional 50 watts and down firing sub, what (if any) are the differences between the two?
