With the number of used plants available on Audiogon, the power plant option is a very viable solution and improvement.
What I have done with both my P-500 and P-600 is to open them up and remove the ferrite rings which were installed by the factory. Then replace the PS Audio ports on the back with the flavour of Oyaide outet I wish to substitute. I liked both the SWO-DX and SWO-GX (Rhodium over silver and palladium over Gold)
This slight mod which is so easy to do, seems to improve the performance of the PS plant units.
