Still making slight positioning adjustments, but getting great imaging now with speakers 5' from front wall and 3' from side walls, and toed in slightly. Once I'm sure of final position I will install the spikes. Just turned on the subs today as well so fine-tuning the sub volume. It was quite easy to find the null and get the right phase adjustment. Since this room is now my office I am looking forward to work days a bit more now. I can't imagine ever getting the itch to change from these speakers. My first "real" speakers were Thiel 3.6, followed by Genesis V (I really liked these but they weren't really going to work for home theater); then next 2 channel setup was Paradigm stand-mount Signature S2 (v. 2); then in this room I inherited some 25 year-old SL3s that introduced me to the magic of electrostatic speakers. While I enjoyed them, I could tell (compared to the Paradigm's beryllium tweeter) that they were getting tired (yes I vacuumed them). So, given that I had the room to accommodate the CLX, I knew they would sound incredible. I am surprised just how special they are. While there may be certain things high-end cone speakers can do better, I doubt for the kind of sound I'm looking for that the CLX can be bettered. I can't say that I have heard a lot of other high-end speakers, but at this point I don't feel the need to. Thanks to Shawn at DaVinci Media for his help in getting me to this point.
