Hi guys, I'm new here. Nice to meet you.
Here's my situation: I have a foam-insert-removed Sennheiser HD555 and a Fiio E7 and I always use the E7's DAC because I don't have any clean analog sources.
I have <$150 to throw around. What should I do?: Buy the Fiio E9 or upgrade my headphones? If the latter, which ones? (I most value neutrality)
