Based on my knowledge, there are two power conditioner brand which are "NON-CURRENT LIMITED". Tara Labs (PM2, Ad6, IDAT) and Synergistic Research powercell. The rest of PCs whatever the brand is, they are not suitable for Power amps.
Tara labs Power C. has this Surge protection feature. I tried both in my amps and even in cascade mode, the result is wonderful. I am still using Tara labs Ad6 with my amps.
cheers ...
