@allhifi - My only point was that around the time the S3 Mk II came out it was similarly priced to the Sopra, and while the S3 is a more musical speaker, it was lacking in the bass, chesty, demanding of room and amplifier.
As for your comments about construction, I really do like the all aluminum construction, but I find your overall take demeaning without good cause.
It will be interesting to learn the full set of cost saving measures employed in the A3. The rest of this post is speculation, so Magico fans, cut me some slack.
I think the high-end Magico's use billet, machined aluminum, while the A3 uses what appear to be extrusions. Not a bad thing, I think.
What makes the A3 a potential killer in the price range (IMHO) is bass extension and sensitivity of a "normal" speaker (compared to the S3) with the fabulously smooth mid-treble of the S3. It could in fact fix everything I complained about in my review of the S3, at a better price point.
Best,
