Yup, brands state whether it's wirewound or not. Do you have any idea how many watts are the resistors used in the HE-adapter? Do some research on which brand of resistors are the most transparent. I used Dale/Vishays.
I might have a friend tag along. He has never heard any proper audio gear before. I think it would be a fun experiment if we can keep silent about the prices of all our gear and let him rank what he think sounds best.
