I felt that the virgo III's were a step down. Better bass yes, but they just don't have that magical mid and upper range that made the II special. The II's basically sound like the worlds best minimonitor, yet they happen to have decent bass. The upper range on them is just amazing. I've probably heard 50 speaker's, and the virgo is definitely in my top 5 list.
The III's sound much more like a good quality, 'ordinary' (boring) speaker. I feel like I can hear the multiple driver's in the system. Maybe it's just a predjudice that I have. I feel that the fewer drivers the better.
They're good, but instead of me thinking 'these are really special', I just thought 'yah great,...whatever'. They just don't have that 'clarity' I hear in the II.
