I have owned SF Concertinos and the build was great until one day pulling my Mit cable out pulled my binding post out! Sumiko would not cover it even though it was under warranty! Good thing my local dealer stepped up to the plate and repaired it for free!
It took trying different cables and several amps to make it sing. A Classe 100 watt Cap100 did it. Finally bass and speed to match the fine vocals. After several years sold it to get a more wife friendly looking system...Kef then guess what Paradigm! When I had the SF it was my 2 CH system and I had a separate 5 ch system. Now I just have 1 system a good looking Paradigm Millenia 200 setup. It took a tube/ss Peachtree inova int amp to tame the tweeter yet maintain the speed of the speakers.
Do I miss the SF? Not really. I also had the Paradigm Millenia Ones great sound too. Had to sell at more than half off retail. The SF sold fast with hardly any depreciation. Bought the Millenia 200 as a floor model for over half off. Point? If you go with Paradigm consider used or a demo model etc. Hope this was helpful since I had both brands and like them both. Though not exactly in the same league as the speakers you're considering.
