Calvin, I also have not been able to warm to the Wilson speakers. To my ears the Alexia's have an airy top end and good sound staging, but have bloated, flabby bass which also smeared the midrange. I prefer Magico's sealed box approach which allows tighter, more accurate bass. Magico also have better build quality than both Wilson and Raidho imho.
I know what you mean about carbon drivers. Wilson Benesch, Proac & Vandersteen all use all-carbon drivers and are generally regarded as sounding natural. Speaking from my own experience, paired with Vitus or Soulution the S5's are capable of drawing me into the music. However to get the best out of them requires careful attention to detail. I've worked hard at building my system around the S5's for optimal synergy, incl: amps, front end, cables, isolation & AC power. The old adage "The whole is greater than the sum of its parts" applies.
Though as good as the S5's are, I would say there are other loudspeakers i've heard which sounded more natural and did a better job of drawing me into the music like the Avalon Transcendents & Crystal Arabesque speakers with the RAAL ribbon tweeter. That's one of the reasons I am upgrading to the new S7's. Magico's latest drivers (incl: diamond-coated beryllium tweeter, hybrid carbon Nano-Tec/Nano-graphene midrange & new 10" bass drivers) are all lighter, faster & much better than the previous generation, whilst cabinets and crossovers have also improved substantially. From what i'm hearing, the S7's approach the complete sonic freedom and 'boxless' sound of the M Pro's which is high praise & just what i'm looking for.
Richard Vandersteen and Alon Wolf are both at the top of their game and building great loudspeakers which are extremely fast, accurate and coherent. It is hard to imagine anyone not being beguiled by their latest offerings incl: the Vandy 7Mk2 & Magico S7. The technology from the S7 will inevitably filter down to other S series models, as i'm sure will occur with Vandersteen. The winner as you say is we audiophiles.
As for cables, i'm not a fan of using cables to 'tune' a system, much as in the same way i'm not a fan of using 'tuning feet' such as the Harmonix to correct deficiencies in a system. Hence I use Jorma cables which are neutral in tonal balance and sound natural. Cables matter, and indeed I have a significant investment in wire. But I don't agree with those who elevate cables to the level of components. I don't subscribe to that point of view. Imho, at that level your money would be better spent on a component or speaker upgrade.
