I read that Andrew Rigby, formerly of Dunlavy, was particulary fond of the 75 watt/channel Rowland Model 2 with the SC-IVa, but I do not know if this is in fact true.
Respected Audiogon member Sean suggests very powerful amplification for the Dunlavys. That said, Dunlavys are efficient at 91 db/watt and don't drop below 4 ohms, so provided they are not being used in a big room, you can presumably get away with low-powered amps.
I owned Dunlavy SC-III's for a number of years and also owned Rowland Model 6's (the monoblock version -- double the power -- of the Model 2), but did not own them at the same time. The Rowland 2 and 6 amps are extremely well made and have excellent power supplies, and are a good example of a wattage rating not meaning much -- the Model 6's can output >45 amps on peaks (they were far more powerful than my 290 watt/channel Bryston 4B-ST). My guess is that they would be more refined than the Sim amps (they are vintage mid-90's Rowland, with battery power supplies and a list price of over $16k when new). With batteries, they now go for about $5k used.
The best sound I got out of my Dunlavys was with a VAC 70/70 Renaissance Mk. III tube amp. If you are interested in more detail, I'd be happy to describe the amp and the rest of the system I was then running.
