Meridian DPS 7000 ? 5200? are these speakers actually worth having as a long term deal...

CMB, are the older 7200s updgradable?

Yes, all DSP7200 speakers can be upgraded.

" Are any of the DSP Meridians worth looking into. DSP 5200 or DSP 7000 would be of interest."

If you're used to Wilson's with good electronics, there's no way you'll settle for a pair of 7000's. Meridian is way over priced for the level of sound quality they deliver. I wanted to try home theater so I went out and bought a Meridian system. Here's my review: They look nice, they're well made and they play extremely loud. 

I've always been a 2 ch person, so I evaluated the speakers setup for both theater and music. Aside from the high price, they're OK for theater. For music, they just can't compete. For comparison, I took a pair of Vandersteen 2's, an Ayre amp and a Wadia CD player, and put them right next to the Meridians. With the exception of volume and bass, the 7000's were embarrassed by the Vandersteen's. And so were the 8000's, for that matter. The 7000's were my surrounds, and I had 3 8000's in the front. Also, plan on buying some expensive cables. Given that Meridian puts both a dac and amps inside the speakers, power cords make a huge difference. Consider them a must buy. The Shunyata's gave the best results, and they were 2k each.

I don't have the time to keep going on here. If I missed something or you have a question, post, and I'll do my best to give you an answer.
