I bought my Epilogs almost 20 years ago, pre Proteus software. I compared Wilson WAMM, Wilson Grand slamm, Goldmund Apologue, Goldmund Analog, B&W Nautilus and chose the Epilog, they are still the best speakers I have heard.
I have heard about integrated digital transmission mods but haven't heard them. I have a standing invitation to go to Switzerland to listen to the latest kit but the prices were high when I bought mine but have moved to a different planet since so I have not been.
I preferred your Animas to your Epilog, and the Yamamura to the big Apologue (as does the owner). I found the Stenheims much different that (at the show at least) their drivers seemed more coherent together.
