OK, so I just bit the bullet on a Parasound HCA-3500 amp. These things are beasts! I am picking it up from the original owner and it looks brand new. Here is my question. I know about the R-44 resistor swap for the Holco 47k resistors, which eliminates the harshness on the top end, but I am considering a full upgrade of the capacitors and many of the other internal from Big Sky Audio.
They upgrade all the caps and such to High Grade/Audio Grade caps, and I am seriously considering the Rubycon Black Gate Caps.
Here is my dilemma, is the R-44 Resistor Swap enough? I have heard it gets rid of the edginess of the top end. Am I going to notice THAT much of a difference on an already awesome amp with the addition of the Big Sky upgrades?
Thanks in advance for your opinions!
