My amp is sounding awesome and i am checking out the possibility of making it even more better by trying to eliminate that little bit of thermal and current noise (if any) and check if it matters to me. Others would have bought a new amplifier costing 3 times more and justified the purchase. The main reason to do this mods are i have the time and budget to do them and all the mods done in the past 3 months have benefited me positively without burning a hole in my pocket.
The present mods i am planning with the resistor changes will be costing me around 1200/- bucks and i am sure, no amp would have ever been built only with wire wound resistors (diy) due to the high cost involved and difficulty in getting the parts as they need to be custom made.
