Fred,
I seem to be heading in a similar direction to you. I have bought Audiopax 5c & 88s and I am housing them on GPA Monaco racks with apex feet to remove feedback from my sprung floor to equipment.
Now I need to decide whether to go for Duo Omegas or play it safe with the Audiopax Ref 100 or 150 speakers. I have heard the 100 & 150s but not the Omegas. Did you listen to other speakers before opting for the Avantgards? Ref 100s in particular?
My source is VPI SSM with XV-1S into Art Audio V1. I like all types of music, mainly classical on FM and Blues, Jazz or Rock on vinyl. My room is 14" x 22" so not far off yours. I guess room treatments will be required to tame the bass although the attraction of the sub-woofers are that you can set the roll off points and tweek them.
I am planning on AN-Vx or Ve cables throughout.
I only hope this is the right decision? Can you reassure me on the Omegas? I know they are very precise. Garbage in Garbage out as Ivor T used to say!
Thanks,
Charles
