Should be interesting how it works with my UM. Also, I just noticed how you may have hinted out that the PFE232 are "over-priced" or under-performing for that price range is absolutely false IMO. First of all, I paid $500 for my pair, and yes I know it's still a lot, but when you think about it, it's definitely within Westone 4, Shure SE535, Earsonic SM3v2 territory, but I find the PFE232 to beat them all in overall ratings. I know this can go on for eternity so I'll leave it at that
