That’s a shame as those hunks of solid wood look beautiful in real life, and fairly small. Having heard two different speakers from the Boenicke range with my SIA-025 I believe there is a real chemistry between the two. And amp-speaker-room integration is ultimately where system matching lies I think.
At Munich 3 years ago Vitus used Gauder Akustik Berliner speakers with the SIA-025. They have a new range 'Darc' which I heard in Munich - very impressive, very Magico-like. Apparently Magico use an SIA-025 in one of their US HQ consumer rooms. Magico are renowned for needing a lot of juice, so if they’re using an 025 to demo their speakers then I don’t think there's much to worry about with regard to the 25W/100W output. If you like the very revealing detailed sound the Vivid probably gave then I reckon you’d like the Gauder Akustik Darc. And it comes in a variety of sizes. Looks great too. Personally I prefer a more organic and musical, less 'hi-fi' sound, at which the SIA-025 excels and at which end the Boenicke's excel, as did the Sonus Faber, the ProAc K6 and the Avalon’s, all of which I demoed with the Vitus amp (I know you’ve read it and someone already linked to it but here's the link once again to the review of a bunch of speakers with the SIA025 :
