I think you were on the right track with the meridian gear. DSP7000's are a great choice as are the DSP5200's for smaller spaces. Either the 800 series or the fantastic G98/G68 with the room eq feature and 1080P support would work great. The surround processors in concert with the dsp loudspeakers offer a synergy and level of control that no other system can match. Theater components require software updates over the years to keep current. Meridian has a long history of supporting their products over the years. I am a Meridian Dealer and would to help in any way I can.
what to address first
I have Theta Casablanca II,standard DACs,Theata Dreadnaught 5x225 amp,aerial acoustic 10T,CC5,5B rears,SW12 woofer,Nordost wiring. Should I upgrade blanca to III,add superior DAC or replace with Meridian processor. Upgrade 10 to 20T and ultimately get monoblocks or replace with Meridian 7000? I heard Dynaudio Temptations that were great. Will 20T be as good for home theatre? thanks!ken
