The magnostatic HiFiMan HE-5 LE seem to demand more from the headphon amp than "normal" dynamic phones. Which is the cheapest amp that can drive the HE-5? Cheaper means less than the amp HiFiMan sell themselves, the EF5, which cost some 500 € here. And for reasons of space and placement I am looking for are solid state amp and no tube or hybrid amp.
I have a Meier HeadFive, would it be a candidate for this headphone?
