Upgrade from Audio Physic Virgos to ???

Hi Folks:
I've been enjoying my Audio Physic Virgo IIs for about a year and a half now, but am getting the upgrade bug. I'm keen to hear some upgrade suggestions. I love the Virgos, especially the soundstage they provide. However, I'm assuming that with more $$ I should be able to get even speaker for my money. I'm particularly interested in hearing from ex Virgo owners who've upgraded and have been happy with their new speakers. I'm also particularly interested in high efficiencey designs as I may move to lower output amps like SET or OTL. A couple of speakers I'd be interested in are JM Labs Mezzo Utopia, AP Avanti III and Coincident Total Eclipse. My room is relatively small though (the Mezzo Utopia may be more appropriate given room restrictions) at about 14by16 feet. Current system includes Blue Circle BC2 amps (75wpc, class A), Supratek Syrah preamp, YBA CD1a cd player, Teres 135/OL Silver/Shelter 501mk2 vinyl rig. Thanks,
Outlier.
