I hear ya! Completely understand it's quality over quantity so to be honest, after all this feedback and different opinions, I'm lost lol
One easy way out is as follows:
1. Define the average sound pressure level you need/want at your planned listening distance. Add ~3-4 dB for overhead;
2. Use a reasonable figure like 87 dB/W/m to work out how many watts you actually need to achieve the spl you calculated at step one. Consider that those watts should be
continuous or RMS at 4 ohms unclipped or 1% distortion... not peak or 10% distortion any other such nonsense.
3. The resulting wattage will be more than you may usually need because it does not account for the fact that you'll be seeing more spl from multiple drivers. But it does allow ample room for overhead for things like waking the neighbors, scaring pets and small children, and impressing friends.
4. After that, it's just a matter of defining the features you want and how much you're able to pay to get the lowest distortion, best linearity and slew rate, warranty, etc..
I put it in that order because an amp/AVR's primary purpose is to provide
gain. If it can't do this right, everything else becomes academic.
You could work backwards from the speakers too, as long as you realize that to be on the safest side possible (avoid the possibility of clipping) the amp/AVR you eventually buy should at least meet or exceed the maximum power handling of the speakers.
Regardless, it will illustrate how few watts you actually need. This is an important point because it dispenses with the bull$hit at an early part of the discussion.
This isn't the sort of advice you get at BestBuy, Sam's etc. It's certainly not the final word on how to sort through the haze either. Others may offer equally useful
methods. I just happen to offer this method because it starts by defining the sound pressure you want before moving on to qualitative issues that are easy enough to read and understand from a spec sheet.
Oh, BTW, people who start you down the path with regard to a certain manufacturer or model without going through the math are asking you to make the same mistakes they may have already committed or averted thru dumb luck. Why? Because their use may not be the same as your use... unless they run the numbers first to confirm. That's the benefit of a method... it leads to tailored outcomes and gives you the benefit of considering each step and determine what's right on your own.
