Using sonicaps in powervar 12?

Hello

I read here -http://db.audioasylum.com/cgi/m.mpl?forum=tweaks&n=96328&highlight=cdc+p

Where he had modified his powercar--i have done everything to mine that he recommened,but using the --------.47 auricaps.

I would think that sonicaps would work just as good and should sound about the same in this application?

The sonicaps are much cheaper than .47 auricaps.I noticed in reading about the sonicaps ,they test twice the voltage of each cap before leaving the factory.I need 6 caps to put on all the receptacles.

I quess what i am asking have any of you had any Experience using sonicaps?

Thx for stopping by
