Hi Lew,
You asked about SET(single ended triode) which would use a DHT tube, The Dynanco is actually a SEP(single ended pentode tube). I haven't heard the Dynaco however professional reviews have been raves(6 Moons review is very detailed). Dynaco owners on this site are very happy with it. I believe for your application it could be really quite good. I'm not familiar enough with either the Dynaco or MAC amp to offer a comparison opinion.
