I always liked the Minis for the price, a fine speaker. I have to completely agree with your assessment of the 20s being brighter than the Minis. The highs on the 20s, with their Aluminum tweeter, are definitely approaching harsh to me with brighter material, and the upper midrange is more "in your face" - more detailed, but not entirely pleasing to me. I like the softer nature of the tweeter on the Monitors, but they do sound a tad muffled in the lower midrange (v2s, the v3s have improved a bit with the new drivers), especially when you compare them to studios in the same setup. I am a fan of soft dome tweeters
and 'Digm doesn't do those anymore.
Given the choice between the two for mains, I would pick the 20s without question. For surrounds, Minis. Many people say the same thing about Minis vs Titans, that the difference is too small, but I had both for a long time, and I can tell you the difference is very noticable, and I'd say you will find the same is true over time with the Minis vs 20s.
