So the question is why do some manufacturers then have ratings such as "200W@8,4,2 ohms
vinylzone25 posts04-10-2021 11:48pmTwo 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.
Mac’s also have those sort of specs because their Solid State amps have output transformers, and they can’t even come close to doubling for each halving of impedance, I’ve never like their sound.
The only I ever like of their was the original tube MC240 on Quad 57's
