My pair arrived yesterday, and they are sounding pretty good to my ears so far. My speakers are Joseph Audio Perspectives 2 graphene. Great depth and very good detail. I particularly like the sound of strings with this pair. I have been using Class D amplification; Rogue Pharaoh, Bel Canto e1X, JR 125's(currently), and GaN; mini GaN and AGD Tempo de gan. These DVA 225s might be keepers! Only gripe, the XLR connector is non locking type, but appears to hold cable tight enough. Also, a 12v trigger option, if possible, would be nice. But focusing just on the sound, this pair has to be the deal of the century! I'll update later this week.
