I like the idea of the LS 50s on the subs. My stands haven’t arrived yet and I’ll talk to the dealer, who’s in Las Vegas, about this. This dealer is a long time a/v shop, but has added two channel recently and has nice gear like Naim, McIntosh, Dynadio etc.
I’m aware of the Isoacoustic stands, but don’t know anybody who’s tried them. As this is a decoupling mechanism, I bought some foam recently and will put it under the KEFs. This was after watching a Bobby Owsinski video on YouTube. But that’s another topic....
