SET amplifier recommendation

 I have been listening push-pull tube amp for a long time. Finally I'd like to try SET. Seems a lot of people moving from push-pull to SET. My budget is <$3000. Looking at Coincident Dynamo MK III 300B. As there is no dealer for Coincident, i can not try it/hear it. Anyone has this? I'd like to hear your comments. i also looked at Decware, Bottlehead, etc. It seems Dynamo is better. Line Magnetic has some interesting ones. But i am not sure the quality can match Canadian made one. 
    My main speaker is B&W 805. Listening space is less than 400 sq ft. My current push-pull setup is CJ premier 15+CJ premier 17ls2+ Audio Research VT100 MKI. Thank you.

@atmasphere Just out curiosity, I plugged the ACA into my 89db efficient Sound Lab electrostatics (the 805 is 88db), and my Vision Acoustics Soloist (air suspension 88db), and yes it will drive the B&Ws, and probably quite well.

+1 mountainsong's suggestion on Mastersound. 

I'm driving a very difficult load Sonus Faber Elipsa 4ohm (88 db effective)
with 30W 845 SET to satisfying levels in my large room without a subwoofer. I'm talking about concert hall levels with no distortion. Check out some videos on youtube with Mastersound driving B&W speakers. Numbers aren't everything.

No doubt! But its not enough power on speakers like that unless the intention is to have the music mostly in background or serious listening at lower levels.

I would add to Ralph's comment that the dynamic range of the kinds of recordings that are listened to (i.e., the **difference** in volume between the loudest notes and the softest notes) will dramatically affect how much power is required. For example, many well engineered minimally compressed classical symphonic recordings require **many** thousands of times as much power to reproduce brief dynamic peaks as to reproduce their softest notes. While many and probably most pop and rock recordings are dynamically compressed such that they require no more than around ten times as much power to do likewise.
