That's a question for @AndrewM888, I suppose.Very interesting. Is there an easy way (w/o soldering) to upgrade THX 789 with these Sparkos SS3602s, I wonder? If yes, how many of those would I need?
Checked the pictures of THX's internals on the other site and it seems like there is no easy way to upgrade. But, if I find the specialist to do the soldering, which op amps should be changed for Sparkos ones?
Note that the SS3602 is a dual opamp, and the SS3601 is the single version. Amps with socketed opamps use different numbers and types of them. According to the teardown on ASR, the THX amp uses 2x TL062C, 4x OPA564 and 5x OPA1602A. At least the TL062C and the OPA1602A have eight pins, so mayyyybe they could be replaced. But they seem to use the smaller SO-8 package, so adapters to DIP-8 would be needed.
