Hi Draevbg56,I have a pair of Dynaudio Special 25s.Last year I was invited to a dealers store hosting Sim Audio. Sim Audios factory rep was showcasing their L.E. line through out the store. At the top, Sim had their huge statement mono blocks driving a pair of Dynaudio Evidence Temptations...Incredible.Through out the other rooms, Sims full line were set up driving other Dynaudio speakers.I do not remember all of the models of Dynaudio speakers set up. However I can tell you Sim is a (verygood) match...As for tube amps, Atma-Sphere, V.T.L. Cary,Also very,very good. Heard them with the 25s.And Im sure David Bernings ZH270 would do the trick also.Good Luck and Good Listening.
