Yes, it is a good speaker. I own a pair for a second system. I disagree with the comment about shrillness; if anything, I find it's treble balance a bit soft. HP in TAS referred to the ribbon tweeter in the IM8300 as second only to the Maggie ribbons. I find it very smooth and if anything a little on the "sweet" side; IMO, good solid state is the ticket. With my Manley 200's, the sound is a little too soft. I find it images well, although not a particularly large soundstage. Very nice midrange. It's main deficiency IMO, is in bass extension; adequate, but not very deep for a speaker this size. A word of caution: inspect very carefully the woofer surrounds. Mine have deteriorated and will need replacement. Gently rub your finger along the surround, and if little rubberry "flakes" come off, they are on their way out.
Good luck.
