The biggest change was adding 6800uf to the power pins of each IC op-amp.
I'd be curious to know how you arrived at 6800uF as the ideal value for placement right at the opamp -V & +V pins. Thanks.

It was by modding a lot of gear. I would always do a power supply up-grade of all the PS caps. Most times I would make them x10 bigger. So, 220uf want to 2200uf. This would almost always make a difference. And I would put 1000-2200uf right on the op-amp power pins. Then one day I realized that I was doing the right thing but to small. I then tried 4700uf on the op-amps and it was good, but not always. The magic would come and go. So, I tried 6800uf and the magic stayed. Even op-amps as old as the 5532 would be smooth, detailed and would seem to disappear, not have a sound that said OP_AMP. Trust your ears. Good Luck, bobwire
If you believe in magic, who am I to question your method? ;-)
