I've given you recommendations. Here.
You seem to have misread my post, though. I wasn't suggesting you get the E7+E9. I was suggesting you get the E7 or E10, without the E9. Either of those are powerful enough.
If you want information:
The Fischer FA-011 has an impedance of 160 ohms and a sensitivity of 98dB/mW. As a result, in order to reach peak volumes of 110dB (often considered "well driven", and much more than most people will ever need), you need 16mW of power into 160 ohms. This equates to 1.6Vrms. Into 150 ohms, which is close enough, the Fiio E7 remains under 0.01% THD+N at 1.6Vrms, and can output 1.87Vrms before clipping. 0.01% THD+N is about one fifth as much as what's usually considered audible (which is 0.05%). At more realistic voltage levels, it stays at about 0.006% THD+N, nearly an order of magnitude below 0.05%. It is a good option for you.
I'm assuming it's 98dB/mW and not 98dB/V. If it's 98dB/V it's one of the hardest headphones to drive in the world, and would need an amp five times more powerful. I highly doubt that's the case
