I am on the wait-list for a UFO25 and the CSP325 preamp. I am on page 11 so I have plenty of time to wait. In the interim, I found a used UFO2.1 and purchased from a Decware forum member without too much trouble if I'm being honest. I have it hooked up to Heresy IV's and just like ned says on his reply before, I haven't found the upper end yet.
It's a great amp, I love the sound, and can't wait for the 25th anniversary upgrade when my number comes up. A lot of people spend time complaining about Decware on various boards across the internet. There are a lot of choices out there. If it bothers you that much, don't buy one. Plain and simple.
(This isn't a response to call anyone out on here.... Just putting in my 2 cents)
