I'm kinda new to the audio thing and trying to wrap my head around so many new facts and theories. One that has somewhat eluded me is the whole concept of speaker efficiency and what amps pair well with what speakers. Short of trial and error, is there a short course of discourse to help brighten the dimness of the light bulb over my head when it comes to speakers? Once I get through this one I'll have another on phono cartridges but that is for another day. C'mon AK'ers, give me your best shot!
