Are you against the idea of moving up the Vandersteen line? But if you do, you will need VS subwoofers, at least with the 3As, as without them 55 watts will be a bit underpowered - assuming you love the VS sound - obviously many do. I thought my 3A Signature and a pair of 2Wqs was a superb system driven by CAT JL2s - 100 watt, Class A, triode. Having said that, I auditioned the Merlin VSMs, sold the VS3A/2Wqs, and never looked back - for me the Merlins are simply among the most resolving speakers made at any price - though not completely full-range, their bass depth is more (much more) than adequate for acoustic jazz, and highly articulate (33Hz-22Khz +/-2db). If you live near the Baltimore area, you can come listen to the Merlins in my place, with 35 watts (EL84 - more than adequate power), 60 watts (6AS7 - OTL), and 160 watts (EL34) tube amps and compare them with the sound of your Vandersteen setup and decide which sonic signature you prefer - they are very different speakers.
