Now that my amp's blown...

Well, now that my amp's blown, instead of repair, I'm thinking about purchasing something else.

Speakers are Royd Minstrels..Source is my old Rotel RCD971.

I listen to all types of music. I was using a modified Sugden A48B, which worked well with the setup.

If I were to spend, say, $500 CAD on a used integrated, what else might work well with my source and speakers?

If i could say i wanted a bit of something more, i'd say it would be a touch more clarity in the midrange and maybe a little more dynamics (which is not to say the sugden is really lacking in either regard). If the whole thing could be more 3-d sounding, that would be great, too (although it's really my room that's very limiting in this regard).
