The Stretta Procedure on Tom Oberheim's revival of the SEM analogue synthesiser:
"The recent introduction of Tom Oberheim's SEM re-issue sparked a spirited debate on the sonic differences between surface mount and through-hole components..."
You have got to be kidding me. No, wait. This is world where Monster Cables is doing good business. I can believe that some 'experts' reckon there is an audible difference based on the way in which you solder components to a printed circuit board.
It's only a matter of time before someone determines that the key to the original SEM's sound is the lead content in the solder – I'm assuming Oberheim is using lead-free solders for the new SEM so that the company gets to sell them in Europe and Japan.
The only real difference - other than the updated specs of the new components on the PCB - is going to be if a surface-mount chip 'tombstones' off the board, giving you an accidentally circuit-bent synth. That's why washing-machine makers didn't use surface-mount components for a long time: the manufacturers worried about the chips being shaken off the board. Given that it's mostly discretes used in the new SEM, as I understand it, I can't see that happening very often, unless you fancy going all Keith Emerson on it.
I need to go find the discussion so I can have a good laugh.
