I have seen many posts where people complain about profiles being thin or muddy or boomy in certain circumstances and they blame it on the equipment and/or the profiles. While this is undoubtedly a part of the problem I would suggest that 9/10 times the issue is unsatisfactory treatment in the room. Most home players and recordists would be better advised to spend £1,000 on Rockwool and other treatments than a new set of monitors or FRFR cab.
There was a thread over on the FAS forum called Your Room Is Shit. Very applicable in this instance.
