Scanspeak? Morel? Dynaudio? Seas? DLS? Hellya high end audio!?

I am surprised with your list of audio companies and choice of speakers as well as active and passive that you haven't listed Hertz/Audison in any of your categories. Hertz makes one of the highest rated SQ systems in the world. If you want to step up your audio game look into the Hertz High Energy Lineup. They are a fantastic speaker. Also for your subwoofer amp since you seem to be an SQ junky I am surprised you chose zapco, to truely get the best out of your subwoofer you will want to upgrade your amplifier. For now the subwoofer I would recommend is the Hertz Energy ES300, it is probably one of the better SQ subs on the market and in its price range it is likely one of the absolute best though you won't be able to find one online. Contact a href="http://www.soundmancaraudio.com/" rel="nofollow"http://www.soundmancaraudio.com//a and they could mail you one as well as discuss prices and really help you with your sound quality needs. Personally I would run an Audison Lrx5.1K five channel amplifier run the HX300 subwoofer in a custom tuned ported box and run the High energy 2 way components active using the crossovers at the amplifier.
