Hi guys, I am trying to integrate with Audio Physic Virgo II's. These are superb in every respect except for extended bass. I have read a lot of good things about the HGS-18. I am just afraid of the integration problem. I recall a few incidences at audio dealers where the sub called attention to itself. The sound was coming from another place, and was more of a distraction than a positive. Comments pleeze, thank you.......Mark
