The key to changing out the capacitors is size. Some caps are just to large to fit in tight spaces so be careful. Increasing the numeric values for Power Supply capacitors will in general produces better bass so if you can fit them in, my recommendation is to do so.
I recently used the Milflex copper caps with very good results in sound reproduction - did not find them bright either.
Happy Listening.
