Campfire Audio Solaris - Quad Driver Hybrid
Well, they're finally here: https://campfireaudio.com/shop/solaris/.
I think I'm about to place an order for them now. The ADLC driver Campfire has right now is easily my favorite DD and I think these would be the perfect compliment to the Atlas.
EDIT: Just purchased a pair. I'll be sure to drop my impressions here once I receive them.
