What does "bookshelf" have to do with it?
You are "good to go" on anything 20 to 1000 wpc.Relic1Golf said:I was reading a book on how different types of speakers require different amps whether it's a full range, electrostatic or bookshelf speakers. I didn't know if there was any truth behind it or as long as it's 100w at 8ohm I'll be good to go?
Your speakers aren't low sensitivity. 100-150W is likely plenty unless you have a massive room or listen at extreme levels for extended periods.Relic1Golf said:perfect, I think Ill go with 100-150w to give me more headroom and B&W speakers arent very efficient so Ill need more power than I originally expected.
+3dB is a 50% change in output and would require twice the power to achieve. So an 88dB sensitive speaker would require twice as much power as 91dB sensitive one to achieve the same output, but that's not the whole story. There are quite a few more factors than that when you start factoring in distance, room size, etc... , but it is a good reference point. Theoretical isn't going to tell you how it sounds though, so the best way to find out is to start listening to the system.Relic1Golf said:I was going to go with an integrated amp but then I started inquiring about the pre-out on my receiver. the integrated amps were limited to 45-60w.I would like to get a tube amp anywhere between 55-65w or if I get a solid state amp, probably closer to 100wpc.
If im correct, an 88db speaker would need twice as much power than a speaker rated at 92db to produce 100db of sound.
