I'm quite familiar with the Virgos, have heard the Calderas, and I've owned AP Avanti Centuries for the past few years and do not find them fatiguing in the least. When AP speakers are set up properly the sound field is laid out wholly behind the speakers which simply disappear. Follow the guidelines in the AP positioning guide to get started - proper setup will pay big dividends - presumably your dealer can help with this. Like any other speaker, the APs will sound better with certain cables over others. I'm inclined to agree with Narrod - look elsewhere in the reproduction chain for a cause of 'forwardness'. Do you hear the same characteristics in the dealer's setup as you do at home? Of course my comments are relative to my system - YMMV.
It might help if you could describe the rest of your system.
Good luck!
