Trying to decide b/t 5 used speakers w/ Rotel Amp

How loud do you like it? The Thiels are power hogs while the monitors are much easier to drive?

Personally, i'd buy one of the first two. Like Elevick said, the Thiels are power hogs and the others ( I believe) are not time/phase aligned. Makes a big difference in my experience.

I have a medium sized room, but there is a possibility of moving sometime sometime soon since I am a student. Should I stay away from the idea of a small monitor with a subwoofer added? Will the Europas match well with my amp? If I don't have a trained ear, and I listen to all types of music, do you think I'll appreciate the sound of all of the above speakers?

I have owned Axiom speakers, M60's, with Rotel seperates. With poorly recorded music, rock, they will be quite brite sounding. They are a very revealing speaker.
