A local ad has just caught my eye, of a guy selling the subject Soundsticks III for 70euros ($75) which to me seems a reasonable deal. I've always fancied matching a set of these to one of my PPC Macs. It would probably be mated essentially to my 1.25GHz iMac G4 17" which I'm smitten with, and have just re-installed Leopard, and together with Coreplayer set up as a juke box player. In this configuration it's great, and with headphones and/or the Imac's original HK small spherical speakers sounds brilliant! - Could someone please advise me if I'd be better off going for the Soundsticks II (several of these around in good condition for approx $64). - Is there any significant difference in build-quality between the II and III models? - Are these considered a prudent purchase 'used'? Or do they tend to suffer over time i.e. plexiglas cracking, sound deterioration etc? - I believe the III model has Bluetooth which could be useful but not essential. Or should I dig a lot deeper in my pockets and consider their ONYX Studio or latest Aura model?
