I never heard of MSR7 pads. I placed an order for them. Thanks. I'm trying to read all posts. It will take awhile. I'm starting with the most recent one & going back; the first one going forward. Should be done by 2020. I found boomy bass on relatively few recordings. I have to be careful judging headphones because some recordings are poorly recorded. Some 60's stuff like Buddy Holly's was recorded in a garage and is better than some new offerings today. I like Madonna's version of American Pie but it sounds like they put a pillow over the mike! I have the Shure 1540 pads due today.
