Thanks Dave and Rob. I still have to settle final positioning of the speakers after they are broken in and also have to re-position some of my room treatments. I prefer having my source equipment and preamp off to the side of the room, not in between the speakers. The speakers image so much better.
I was bitten by the Omega bug several years ago when I purchased a used pair of Revolution's (with alnico drivers) from Zybar (George). Next I picked up a used Decware Zen SET amplifier, modified for 8 ohm speakers. After a bit of tube rolling, it was all over for me - except for upgrading along the Omega and Decware pathway!
