I'm pretty sure no one on the message board has done this, or at least admitted it publicly.

I can tell you that my Decware journey began with a pair of UFOs, configured as balanced monos and they were so good I got back on the waiting list for a pair of UFO25s. Sarah was announced while I was waiting and I briefly considered changing my order to 300Bs. But sanity prevailed, my UFO25s arrived a couple of years ago, and long story short I'm amazed every day at how great they sound.

I'm confident your amps will sound amazing, once broken in. I hope you'll share your experience, and your tube choices and the rest of your system, with us.
