Thread Starter 
Replaced the original IRF630 Mosfets with IRF510.

what did i get out of this? clearer sound all around, the IRF630's highs kinda run together and its hard to tell whats happening, also bass was a big issue with the IRF630 it just flat out sounded awful i will not go into detail on that it was not pretty.
for the next few days i am going to revisit some CD's and see how the sound has changed for better or worse.

Sounds like quite the project. Commendable, sir.
