Thank you for all the replies. The Sennheiser HD25s are a bit too pricey for me at this point.
I read a bunch about the KRK KNS-8400 and Sennheiser HD 280 Pros and if there is a common theme it is that the KRK does not reproduce bass very well and the HD280 has too much lol
I am sure they are much better than what I had though :-)
When reading about the KRK KNS-8400, it seems to be compared to the AT ATH M50. Some prefer the KRK and some prefer the AT.
I should have added that I do have M-Audio BX5a monitors too so I don't just have the headphones.
Thanks
