Really nice result, there. Mine aren't as efficient (my woofers are only 6's) but I'd describe the sound the same way. The point source characteristic provides for excellent and robust imaging, and a very relaxed though dynamic sound. The sound doesn't change as you move like with most other speakers. I don't think there are any other speaker types (SEOS and other Geddes derivatives probably come closest) that do such a good job of not sounding like a speaker is making the sound. The brain doesn't have to work hard at all to suspend disbelief with these.
I really wish there were a way for more people to hear Synergy speakers in home settings, there just aren't many installations out there (and Danley's company is pursuing only the pro market so that leaves only DIYers). I tried at MWAF this year, but with only three minutes of listening in a non-domestic room (and quite lame tracks being played, at that!) I don't think any particular impression was made there. Hey, if anyone around the Cincinnati/Dayton area cares to hear these, drop me a PM!
