Rudolf,
I am not familiar with the ELAC system. I only have a pair of their Debut 6 for a bedroom system. I too have the GCD and M700s and now am a beta for the Stellar Phono. I also have a Manley Steelhead that is up against the SP. Started listening to it on Saturday and perhaps put in 10 hours of listening over the weekend. I need to formulate an in-depth review in a week before the 1st, but I am captivated and transfixed by things I have never experienced with vinyl playback: balance, separation of instruments and people, disappearance of the walls of my listening space, giant and deep stage. Detail and punch in the bass. Detail and dynamics in the mids and highs. And micro-dynamics. Ok enough for now. I can tell you I’m not parting with it. How it stacks up against the Steelhead? Stay tuned.
Steve
