I have not heard either specific current models, but i have heard a LOT of Vandersteens over the years, and some of my dealers were RV's dealers. I owned 2s, 2Ces and 2Cis and had my electronics driving the full-on 5 system at a couple of local dealers. I even heard the old 1Bs (back when the 1 series were an inexpensive, 2-way system, at roughly $700/pr.) I date myself.
Given that you have modest (but yes, good) and lowish power electronics, that has to be a consideration - and Vandys are among the easiest speakers to drive. Not only are they relatively efficient, but their impedance is pretty easy on electronics. Always musical, they respond well to better input material and to good setup in the room. Vandersteens' sins are those of omission, not commission.
You really need to listen for yourself, but with $10k worth of equipment driving them in a dealer, it may not reflect your real-world situation -- and i try to avoid the "slippery slope", or "cookies and milk" or whatever you call the spiral that can result :-)
