The EF5 has a maximum output of around 15Vrms. That's over five times more voltage than the K701 needs to reach 110dB, which is really loud already. That means the EF5 is capable of driving the K701 to around 125dB, maybe more depending on that particular K701. That's enough to damage your hearing permanently within a minute.
So why do you need it that loud? What benefit does it bring you? What benefit does it bring you when you don't even use that volume, when you keep the knob turned way down? The other amps you've tried are perfectly fine. Low distortion, plenty of power (exception there being the Pico, maybe).
The "potential" you discovered was more likely that not:
- Distortion from the amp
- Coloration from the amp
It's great that you like it, but why continue the misleading trend that others need so much power? Why mislead with something like "the big difference does not show up until you start sending the signal through a desktop amp"? Why does it matter if it's a desktop amp or a portable amp? Because one's bigger and shinier and looks more impressive?
Lol, this is hilarious, you haven't heard the K701 through a EF5? yet you are telling everyone what I heard is distortion, coloration or placebo & then saying I am misleading?
