Thank you @rocray @tablejockey. I fell in love with Sonus Faber years ago and had a couple sets. My last set were Olympica 3. My dealer and I discussed a levels up and down from the Amati. Even though the next step up was twice as expensive he discouraged it. We also discussed a lot of systems he implemented for clients. He helped me connect the dots from my own observations I had made in the past on the subject of sizing. I really consider this current system a collaboration between him and I. It is also his favorite system. We have similar tastes… natural / musical system. As opposed to ear bleeding detail striped of musicality. He constantly complements the space… one of the best he has ever heard.
Also, when I had ribbon speakers the stuff in between and the bare wall was not detrimental sonically (I tried with and without). But when I switched the dynamic speakers, wow, big soundstage improvements removing the components and treating wall. Now the soundstage goes back 10 - 12 feet actually behind the wall.
While initially with my speakers set up toed in (most typical) the soundstage was confined to between the speakers… it opened up as I moved them to no toe in. The heavy Afghan made a big difference in allowing the soundstage to increase in depth. Now the speakers disappear (one of their abilities)… But to get there, I’m pretty sure the space of my room was required as well as treatments. My room is also highly asymmetrical, which is also really helpful.
