I have a pair of 906s in a second system (computer audio mostly) and I’m very happy with them. While they don’t dive deep into the bass frequencies (well, after all, size matters) they do give a wonderfully balanced, musical presentation, excellent transients, and a very sharp stereo image. I find them a pleasure to listen to though they’d probably benefit from an upgrade in amplification, which I intend to do at some point. (Right now they’re being driven by a rather old Arcam A85 integrated). Of course you’ll want to treat them to good speaker cables, too. I’m using Morrow SP4s and they seem a really good match. If you're buying the speakers new, remember that they take about 100 hours of playing to find their voice, so have patience with them.
