Zu Omen Def's, Tekton Pendragon SEAS, or Omega's?


After a ton of research, I've, more or less come down to these as my best speaker options. I am looking for big sound, even in my limited space. My room is 10x10, with a built in shelf, in front of which the speakers must be positioned. Listening distance is 5.5 feet, and the speakers must fit into an equidistant footprint 5 feet apart forming a triangle with the listing spot.

That hasn't presented issues with some larger speakers, as I've borrowed both a friends Harbeth 40.1's, and another friends Gallo 3.5's which both worked very well. However, both are too inefficient to work with the amplifier solution I want, and the Harbeth's are far, far beyond what my budget can handle.

I've communicated extensively to both Sean from Zu, and Louis from Omega/Hoyt-Bedford, each of who are simply great and incredibly helpful people who truly care about audio and music. Both have a number of speakers that they say will work exceptionally well in my listening space, and with the medium powered class of SET amps that I plan to use them with (12-16wpc)

I've also read many, many remarkable personal accounts and reviews of the Tekton Pendragon (clearly too big for my situation) and, much more recently the Pendragon SEAS/SE, which was designed for smaller rooms. I've not yet spoken to Eric at Tekton, but understand they are swamped with orders. I'm also a little concerned that people who have commented on the smaller Pendragons are using big power amps to run them, so perhaps they will not match up effectively, as I would have expected, for my intended SET amplifiers limits. They appear to be a spectacular value otherwise, so that would be disappointing if true.

I would greatly appreciate any commentary from those of you who have heard at least two of these speakers and can compare them. I have not had the opportunity to listen to any of them, and while they all offer an in-home audition period, it's still a great leap of faith to actually make the move and place an order for one of them.

I owned the Pendragons (non-SE) and Zu Omen Defs. You can't go wrong with either one except for one concern: will the Pendragon SE overload your room with bass? That's the biggest question that you need to answer besides the amp question.
I am using Reference 3A de Capos in a 12 x 17 room open on the sides with a 4 watt decware amp and pretty loud with good bass
It is all too bad that member Johnk discontinued (with disgust) participation in these forums.
That is a genuine loss here.
I'm in a similar position looking at the same speakers but for HT application. What SS amps pair nicely with the zu omen def vs with the tekton pendragon seas?
A couple people have mentioned the possibility of the Pendragon SE's bass overloading the room. Everything else about them sounds very appealing, but perhaps I need to cross those off the list? I know they were designed for smaller rooms, but possibly not as small as mine.

The other concern raised was that unlike the original Pendragons, they are 4 ohms, which I didn't realize, and that can cause issues for SET amps.
