"udging by your answers, I can see that my question was not specific. What I am or was (doesn't seem like I'm going to be able to leave SET) considering, is 100 of the sweetest SS wpc that would bring out the best in the Definition 1.5s and [if possible] retain a tubey sound? Better?"

Do not count my post..........it wasn't directed towards you.
As to the original author's question.............if it has to be on all the time, please consider RWA 30.2 amp. It runs cool all day long has about 40wpc (which is more then enough), sounds great with Zus and has SET amp characteristics. No.......it did not fool me or anything like that but it is definitely on the warmer, richer side. Since it runs on batteries, it is extremely quiet as well.
But do not take my word for it, check the 6moons reviews and users feedback.
