That comparison was with the older mk1 Hsu speakers. Another thing, having heard quite a bit of Polk Monitors and mk 2 HB-1s, there is no way I would go for Monitors, in fact I regard them as only one step above the cheap, hollow Sony speakers. For almost every Polk speaker I have heard, the louder they get, they worse they sound. At a certain point all treble blend together in a hissy mess. In my experience, the opposite is true of the Hsus, the treble is a bit recessed, but separation and soundstage really come out when you turn them up a bit. However, I do think the bass is very well controlled in the RTi towers, but they still have the treble problem, if not to the same extant of the Monitor/Tsi line.
