I guess few of you had the chance to listen to Gryphon EOS2.
I’ve heard it and I think for under $25k there is no better floorstanders. I’ve heard it driven both by Jadis I70 and Diablo 300. It sounded really good with the Jadis and more muffled with the Diablo, so I think it will sound good with the Octave.
I wanted to recommend Tad Evolution 2 as well, then i remembered the bass is kind of lacking for those but do consider them if you don’t mind a sub.
