Pomyślałem, że wrzucę a propos jednego (zamkniętego już) tematu, który pojawił się ostatnio.

Wypowiedź niejakiego Mike'a Soldano:

"Well, Dave, I don't know who you've been listening to or what you've been reading, because they're just plain wrong. Here's how it works: If the load is lower than what the amp is set for, like using a 4 ohm cabinet with the amp set at 16 ohms, the power tubes will be worked harder and will run hotter. This, of course, will shorten the life of the power tubes. However, if the load is higher than the amp's setting, like using a 16 ohm cabinet with the amp set at 4 ohms, the voltages in the output transformer will be higher than normal. These excessively higher voltages increase the risk of arcing, which can destroy the output transformer and/or tube sockets. That's why running an amp with no load at all invariably ends up blowing the output transformer. I'd say tubes are easier to replace, wouldn't you?"

W skrócie: Niższa impedancja paki jest be, ale wyższa może zrobić bardzo kosztowne bum.
