More power than the E12?
Which headphone are you using with it?

Fostex Th600

I use the E12 with the T40RP MK3, which has less sensitivity (91dB vs 94dB) and especially higher impedance (50 Ohm vs 25 Ohm), and I can't even go over 12 oclock position in high gain.
Go here and input 91dB/mW and 25 Ohm:

You get 120dB SPL with 400mW power. And 120dB is pretty loud.
