sonus faber, vienna acoustics, proac

I would anyday go for the Proac D15, this is mainly due for my bias for Proac speakers, but not fully. I believe the the d15's are better engineered and built, yes built better than even a sonus faber product. I have a pair and I can say that the veneer work on my speakers( i have a d38 also) rivals anything I have seen by any manufacturer, and the assemblu otherwise is top-notch, pure high quality british product. The down port design and the LF extension of these speaker work very well in small rooms, I have mine driven in my 11*13 bedroom by a 30wpc Linn Classik and it yeilds impressive results. But if you want the best, go for the new d25, i heard a pair and think that they might be the best sub-6000$ speaker ever! Frankly, you wont go terribly wrong with any of these speakers they are all wonderful, but in my opinion the proac edges ahead!
