Very well written! Great review, all in all.

The one thing that surprised me was the tube effect on the sub, that the notes lingered. I never knew that they effected the performance like that, and thought that the tube subs were downright superior to box subs. Boxes do have some advantage, and I wonder if the HSU tubes have the same lingering effects as the SVS. Is it brand specific, or is it a law of physics thing? A question for another day, and another comparison, I suppose.
