I have 3A Sigs, driven by an Ayre V-5xe. Killer combination. That said, having recently heard the Quattro CT at Johnny Rutan's place, I would say that that is a big step up from the traditional Vandys (1, 2, 3). If it is feasible to wait a bit longer to swing Quattro CTs, that what I would do (and would have done). The Quattros would reward some upgrades in your front end.
