Sonic Frontiers Line 3 and Power Condtioners

I am wondering what people are using for power conditioners on their Line 3's?

I have a 5 year old Line 3 SE. I just had the third power supply failure in that time. Each time it appears the right channel power regulator has failed. Has anyone else had similar problems?

One suggestion from SFI is to look into added power line protection. I understand that SFI pre-amps have problems when ran with PS Audio equipment that has multiwave capability. I can see where that makes sense. But is the Power Director and UPC equipment without the multiwave a good choice? What about other brands?

I have been reading reviews on Monster, Richard Gray, Brick Wall, Tice, PS Audio and a dozen others. I think I have learned to look for isolation tranformers, stay away from surge protectors that use MOV's and be aware of current limiting But what products offer these without killing the pocketbook? (I know a $3K - $5k preamp deserves $$$ to be protected, but I can also buy a new amp for a few $K.) I think I am at the point of more confusion than conclusion.

Some folks swear by each of these, and others say they cause significant sound degradation. I am not after sonic improvement, though if I get it, great. I am after power line protection that won't degrade sonic performance.

Any recommendations?

Tnx,
Rick
