Well Opus88 and Jaguar, if the P3 impressed you that much, you should hear the P3 Signature! :)
Robert has also just come out with his latest, the Alethias! and the Alethias! Signature, which I have not heard yet.
The P3 Signature's are stunning though. Right up there with the VD Revelation and PAD Dominus as the best cords I've heard. The P3 Sig's top quality is it's clarity and focused presentation, yet it's not edgy in it's presentation, as I've found the Nordost Valhalla to be, IMS.
FWIW, The VD Revelation's strength is the absolute power and ease with which it handles music. If you think the bass is great with a RSAD P3, you should hear a VD Rev. The Dominus' area of expertise is a tubelike midrange liquidity and purity which is stunning. I've heard many cords, and these three I hold in the highest esteem. Of couse, that is all IMS, IMHO, YMMV. :)
