No real suggestions but i used to own a set of these speakers and they're very good for the money but the tweeter can get a little harsh when pushed hard so you should be looking for an amp with a smooth top end.
I had mine on the end of a marantz pm6010ose and found the combination good at normal sound levels but they got a bit hard & brittle when cranked up.
You're best off getting a home demo so you can have some proper relaxed time to form an opinion on the kit you're trying in familiar surroundings rather than sitting in a dem room on limited time.
I'd personally try the budget models from Rotel, Arcam, Cambridge Audio and Nad but there's plenty more out there...
