It's a flawed argument though, because there are many headphones above HE500's price range that have looser / less defined bass still. Hi-fi isn't just about supreme "top 5" bass definition otherwise a big chunk of threads would have to be removed from summit-fi.
Edit: but I do concur that stock HE500s have some lacklustre traits that in my opinion prevent them from giving a truly high-fidelity delivery of performance. It was a big reason why I dipped so much into modding them in the first place, to get them to a state where they sound very hi-fi, and I think I got pretty close.
