I am a fan of A3 too. I'm selling my other gear to finance purchase. Seems the review at Soundstage Ultra mirrors what I heard with a short demo at dealers. The dealer was using Hegel 390. It's weird someone says treble was agressive! I never heard Sopra 2 so I can't comment but I did hear Kanta 2 and from quick listen speaker is leaner and not as coherent and lacks air compared to A3!
