Rademaker,
Having auditioned both of these extensively, the Aurum Cantus came away as the better sounding speaker to my ears.
The SFs sounded very nice indeed, especially with Classical music. Workmanship, as expected, is first class. In my opinion, they were not as quick or full sounding as the ACs. The soundstage exhibited by the ACs was markedly bigger as well. No doubt that the AC's ribbon tweeter a big contributor here. In addition, the ACs came off as more life-like, with the SFs by comparison more analytical.
Given the SFs reputation, I really expected them to be much better. What was unexpected was how thoroughly enjoyable the AC's turned out to be. Also unexpected was the first rate build quality. Sounds cliche, however they really must be seen to be appreciated.
In the end, my decision was purely based on what sounded best and, to my ears, the ACs did it for me. So much so that I voted for them (the V3Ms) with my wallet and couldn't be happier.
You can check mine out by hitting my systems link (Second System Sanctuary). BTW - that shine is a result of 14 layers of hand rubbed laquer. Gorgeous to look at and to listen to! As always, YMMV.
Cheers,
Garry
