In a reasonable size room, you will have NO problems.
Just try to make sure the VSI60 has the newer KT120 tubes
they are now shipping them with because it gave them a bump from 45wpc to 55wpc. These are conservatively rated, and real practical power rating would be closer to 100wpc in real world application. My room is 27x17x10 and I had Vandersteen 2CE Signatures which had sensitivity of 86db/1w. Yours are 89db/1w, which may not sound like much, but yours need HALF the wattage versus mine to achieve the same level.
The VSI60 is a magical amp. Mine has 200 hours. I am going to have to part with it because I just upgraded to Revel Studio2's and they eat juice like crazy so I've gone to 350wpc Pass but am staying with an ARC tube pre. This amp made my Vandersteens come alive with music like no amp before and all the ones before were far more expensive.
