Two possible reasons. First is if it's a tube amp. Most use transformers so the different taps all put out the same wattage. Second is the amp is current limited.
Possibly Ignorant Power Question
Hi all,
I've been looking to up my two channel game and am looking at nicer integrated amps. In the process many have said "look for power that doubles as ohms halve" meaning 100W@8 becomes 200W@4 etc. So the question is why do some manufacturers then have ratings such as "200W@8,4,2 ohms". I thought you wanted the power to spike, to rise to the occasion of a heavier load?
If there's a thread on this that exists already feel free to point me there.
Thanks!
