I've inherited my dad's old Realistic STA-90 receiver, but have no speakers for it at the moment. In general, what should I look for in a pair of new speakers that would pair well with this particular receiver. I mainly listen to vinyl on a Technics SL-B2 TT. The receiver has an output of 45W RMS, correct? So I am guessing a speaker in that RMS ballpark, but I am looking for suggestions!
