I have quite a few WA chips now, lots if semiconductor chips, capacitor chips, a few Cable chips and a few inductor/transformer chips. What it all comes down to is one needs to try a WA chip one at a time and see if it improves the sound. If it doesn't improve the sound try to find another location for that particular chip. For example the transformer chip did not work on my amp's toroidal transformer but it worked on the coils for the AC filter in my Oppo and next to the transducers in my headphones. The Cable chip did not work on my interconnects or power cords but works nicely on the circuit coming into the breaker box. On banks of capacitors I can use one large capacitor chip to cover four caps.
