Tube amp for Zu Omen


Looking for recommendations for a tube amp to drive a pair of Zu Omen DWs that are on order. So far, on my short list for consideration are the Decware SE84UFO (or the SE34i.5 Rachel), the Coincident Dynamo, the Line Magnetic 211iA and the Cayin A-50T. Scanning the forums, I almost pulled the trigger on the Decware SE84UFO having heard about its holographic soundstage and transparency. However, that the 2W seem a bit too low in my 12 x 20 room. Also, tube rolling isn't an option with that Decware model if I wanted some flexibility. I've also heard about the Bottlehead Stereomours but am a complete newbie so dont have the confidence or time to work on a DIY project. Are there any other brands I ought to consider given my rather modest budget (would like to keep it under $2000 or so)?
I listen to a mix of folk (Dylan/Peter Paul Mary), Fleetwood Mac, Dire Straits, Floyd, jazz (Brubeck, Miles Davis, Diana Krall, Buena Vista Social Club etc.) and I plan on playing at low to moderate volumes.
Appreciate your help!

I powered a pair of Zu Unions with Atma-Sphere MA-1's.
Holy Cow, that was sweet! They were pretty close to my Vandy Treo's.
Thanks, Ralph.

I would try Quad Classic iis or an Almarro A205 

I prefer Melody to Line Magnetic, but ymmv.

I have always heard that Atma-Sphere amps/pres are outstanding with Zu speakers. I have a pair of Omen Defs and would love to find out once funds become available.
