I have never heard the combo in question, but am quite confident that it would be a good match. I own a 270, and have personally run a variety of different speakers ranging from Magnepans 1.6qr, and 3.6 to Dunlavy scIV/A's. I have also heard it drive a pair of full range Sound Labs. Not once did it seem underpowered or slow. In fact, quite the opposite. The ZH270 running the Magnepan 3.6 was quite a stunning combination. The Virgos From what I have heard are capable of very good detail and dynamics. This being the case the Berning might just be a match made in heaven.
Best of Luck,
