I have owned all three versions of Virgo's and found the III's are the best out of the group to my ears. They are much harder to set-up than the first two versions. Tubes seem to work better for my taste. Each version I have tried both with SS and tubes, the tubes always sound superior on the Virgo's. Can not comment on the Avanti III's, but looking forward to hearing the IV's. Just my experience as a long time owner of AP products.
