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.

Yes the ENZO is new. I am reviewing a pair right now which will appear in an upcoming TNT-Audio.com article. My initial impressions are this speaker is a winner! small footprint and big sound. Stay tuned for more.
You can check Steve Guttenberg's short review of the Enzo.

And for all the Steve Guttenberg naysayers out there, I am just pointing out a review to Nightfall.
I just took delivery of full size Tekton Pendragon's and they are the best speaker I have heard south of $25k speakers, and they may be even better then that level (to my ears)
Someone earlier recommended you give the Bogdan Art Deco a try. The Bogdan is 88 db. Since you plan on using an amplifier between 12-16 watts, I can assure you, that combination would be a disaster. If you use said amp, and depending on WHAT you listen to and how LOUD you listen to it, I wouldn't go with a speaker less than 96 db.
Also, 16 watts is hardly anything. So, I would not only go with an efficient speaker, but something with some surface area, say 10" woofers (maybe two). I used to own a pair of Zu Essence speakers. They had 10" woofers. Granted, my room is 15' wide and 25' deep with an open kitchen behind it, but the Zus did not have any bass worth bragging about believe me. I drove them with a 30 watt tube amp and, believe it or not, a pair of 300 watt digital amps! Still, very anemic bass. So I would think the Pendragons with their dual 10" drivers would suit you better.
