I agree with the comments that there is an equation here: amplifier output / speaker efficiency, and that speaker efficiency usually matters more.
My Altec 604Cs are 101db, 16 ohms. That’s way more efficient than most stuff being made today.
What actually determines volume power? Is it watts?
I have a Yamaha AS-3200 amp. It sounds beautiful and has a really good open sound. The problem is I like my music loud since I live alone and typically I have the volume 70% and with some recordings it is not high enough. I need a amp that has more power/volume.
The AS-3200 is 200 watts at 8 ohms. I see many amps, even much more expensive ones (like the Yamaha M-5000), are also at around 200 watts per a channel at 8 ohms. I am going by 8 ohms for my speakers and also the worse case scenarios. Does this mean if I had a more expensive class AB amp like the M-5000 I would still be listening at 70% volume and getting the same power/loudness? If not, then what actually determines the volume power if not watts?
