@testrun I’m considering the Cary SLP 05, moving from an RP-7 like you, and also into a GaN based amp (LSA Voyager 350). So I am very interested in how it is working out for you? And did you get the Ultimate Upgrade?
We have similar systems. I too have the Bricasti M3, and I was going to buy a pair of Joseph Pulsars, but bought Fyne F1-8 instead.
I also had a pair of Audions for a short while but returned them. I am surprised they have enough grunt to power the Perspectives.
