Virtual Systems - New Gear

I know that Audiogon tries to be though in their listing of equipment to populate your virtual systems. But sometimes I buy pieces that aren't listed. (And no, I'm not talking about crap from Bose) Is there a way to suggest for inclusion a piece that may have broad appeal. Such as the Audio Research Reference Phono Preamp, the Thiel SW-1 Subwoofer, or the new Audio Research Refernce 3 Preamp?
