For only a $1,200 investment, I think I did pretty well. I would definately like to upgrade my sub, but aside from jumping up to the $5,000 range, I don't see a system sounding any better to me. Any comments and/or suggestions are always welcome!
I'm a big fan of MMGs and subwoofers. Transparent mids and tight bass! Great combination. I have had a lot of experience with low end RELs including the Q150 and Strata III. If you decide to make the investment to replace the B&W get the Strata. It is great. I currently have it paired with Martin Logan Scenarios. As long as you don't have a really big room, this is about as good as it gets.
If you are looking to upgrade the sub, I would suggest a REL Strata II. I used to have MMGs paired with an Audio Refinement amp and the REL; it was great. Since then I have upgraded the MMGs to Martin Logan Scenario.
MMGs are an excellent anchor for great budget sound where loud volume is not required
