Hello AG,My requirement stems from my online education that tells me 75 Watts @ 8 ohms just a'int enough power to bring out the best in speakers rated at ~<88 db efficiency.
75@ is good power for most of speakers. And will be just about sufficient for multidriver speakers. In my small bedroom 100sq.ft. I noticed I hardly use 40 watts. We listen to only few watts at normal/little loud listening levels. It is problem if we listen contineously loud and at transient peaks music/movies, that speaker and amp distorts. But at that level we are probably somewhat immune to it.
Though you have right approach I dont think you will have problem with little less sensitivity. Ofcourse avoid hard to drive speakers since you already have purchased the amp.
Regards
addition : Reason for my previous post was becuase some companies are very liberal with their sensitivity specs. And just because of long term brand name get away with horrible fq. response and distortions. But still people like them. Because they like the sound so no problem.
