Sorry if I missed this topic already, figured we might as well have an opposite post to mark what you returned today to help others avoid bad deals or sound that just wasn’t quite right for you. The purchased today post seems pretty popular already!
Today I returned my NewFantasia balanced cable for the HD6xx. It worked but the braid had a permanent twist to it which was annoying but didn’t effect the quality. I ended up going with the Hart Custom cables and for slightly more money due to the color / length choices, I’m much happier with this cable instead.
I recently returned Fostex T60RP, both cans had a horrible creak and the left had a slight rumble in the low frequencies, the right was much worse. Talked with Ryan at ModHouse and was advised it would be better to return. (ended up with 177x for that spot in my headphones but still have some Argons on my radar down the line)
