The point that the SF's aren't as bright as the Magico's is spot on IMO. The Magico's can sound bright if mixed with the wrong ancillary gear.
But to be clear, I very much enjoy the sound of Magico's...and I think their line is quite fine. Having said that, i don't think the lower models are anywhere near as great as the models from say the A5 on up. The A1 and A3 are not that impressive to me. SF has changed their basic sound since Franco left the company, it is now more of the middle of the road than it was before. Franco's designs tend to be, at least to my ears, almost unbeatable. Yet, they can tip to the warm sound of the spectrum...again with gear that tends to lean that way. Magico's can never be said to be too warm! Since the SF's that I use are fronted either by a ss amp or by the aforementioned Jadis amps ( using KT150's and not KT120's) I think they are a very simpatico combo. Magico and Soulution are an interesting match up. I like the sound and I like the neutrality and detail...but I dont like the ease that the tweeter gets hot.
Probably an ideal tweeter, and this is one that I think is pretty close to SOTA, is the YG billet dome..very impressive...and the best of both worlds, IMO.
