Entry Speakers for McIntosh MC240/C22

I recently inherited an MC240 amp and C22 preamp from the early 1960s that were my grandfathers. Single owner, I'm told they were refurbished recently (haven't been used in at least 2 years maybe longer). I listen mostly to indie rock but also some jazz and classic rock.

I'm basically starting from scratch, so need speakers and a turntable. Eventually hoping to get a DAC. I'm a student, so have a low budget, hoping to be at/below $500 for speakers. I've been looking at paradigms and PSBs mostly, from all the great reviews they get for their lower-priced lines. I don't mind buying used or waiting for a deal.

I'm worried about the low power of the MC240 w/ speakers, especially since I can't test on the equip before i buy.

Advice? Thanks!
