I'd probably give the 3020's ago even though I own the concept 20's, 40's, Dali Zensor 1's. I wouldn't assume perforamce/appeal simply based on price. They're using a newly designed tweeter, woofer and cabinet and therefore could have a sound and presentation that one might find more appealing than the concept 20's despite the lower price.
Case in point I prefer the concept 20's for stereo music than the Dali Zensor 1's but I prefer the Zensor 1's for movies because the Zensor 1's are more agile, focused and more forward which works better for movies in my opinion, couple them with some good subwoofers and they can be very impressive for the money, plus the Dali Zensor range has an excellent centre speaker to match the 1's, the QA concept speakers don't. The concepts 20's are great for music though because they have a very big airy sound that's very laid back and easy to listen to but I find this presentation less effective for movies. When I switched over to the Dali's from the concept 20's for multi channel movies I found myself prefering Dali's quite a bit more.
I use to have 7 Kef ls50's running 7.1 in my home theatre but ended up downgrading to the Dali Zenor 1's and Dali Vokal(centre) for financial reasons and to give you an idea how good the Zenor's are for movies I actually don't miss the Kef's at all and I payed over 5 times the price for my Kef setup versus the Dali's, I do miss them for stereo music though. I'd be curious to see how the 3020's and matching centre speaker performe for movies, they could give the Dali Zensor's a run for their money.
