I feel like part of this would be due to not using the amps correctly. The low frequencies <40hz (approximately the fundamental of your E) are usually cut or rolled off by a high pass filter in amplifiers. A few that don't have this will seem underpowered when they're really just trying to amplify these super low frequencies that we can't hear. I believe SWR has this issue?
Anyways, I'd be interested to know if people are using the built in high pass filters when they report these results or if they're trying to amplify within the 10-30 hz range and creating flub while driving the amp and their cab too hard. The Peavey has a built in HPF but I'm assume it needs to be manually switched on/off or whatnot if I read the specs correctly.
Another thing to note is the frequencies and THD (total harmonic distortion) that each amplifier is rated at. Often these are manufacturer specific and somewhat non-comparable. Old crates rated at .5% THD where as Ampeg often used 5% THD and they both had the same parent company. Neither gave the pitch of their sine at rating. Peavey noted it's rating at 1kz. I don't know how much of a difference that'd make, but I'm sure it has some effect.
