AP may have used some BGs on Tom's Analog & Digital cards. The he caps used on my RCS were Rubycon ZA, ZL or ZLG.
There's a lot more to AP's TacT RCS upgrade than just replacing a few caps.
Anyone that's listening to a stock TacT RCS is missing a lot.
Of course the replacing of caps is only part of it. There are BG series that measure at the lowest levels ever manufactured (FK at -160db),
it's the circuit that is paramount.
The ruby "Z"'s are very good, but the aftermarket price of BG caps speaks volumes.
