I always ran my SCIVs with tubes. I have used custom built 60 watt monos and Audio Research amplifiers with exceptional results. I personally have not used solid state, but I have heard SCIVs with Electrocompaniet and they sounded very good.
SET amplifiers? Maybe on simple music, but more complex music could be a problem.
