Design flaw in Esoteric DV-60?

I live in the Pacific Northwest. We have lots of storms here in Puget Sound. Earlier this year we had a momentary power interruption. There must have been a spike in the power supply, which for some reason, caused the DV-60 to turn itself on from standby. After that, it no longer would do multi-channel playback.

So, I sent it in, and the most expensive board it has needed replacement. It cost $1000 to get it back. Back it came, only to have the same thing happen a few months later. To me, this shouldn't happen. I did think am I crazy to spend so much money? Probably, but I really like the thing, I even bought a spare transport mechanism so when that goes bad (it doesn't have the bullet-proof transport as in more expensive Esoteric players), I have a replacement ready to go.

My power is a dedicated line, goes through a PS Audio Soloist, and then a PS Audio Power Plant Premier, which the DV-60 is plugged into. I am in touch with PS Audio and Esoteric, They claim it's not their fault, so who do I turn to now? Did someone drop the ball when designing the power supply? Does PS Audio have any culpability in this?

I'm hoping one of the genius's (you know who you are Ralph and Al), or someone with the background in the EE field, might have some ideas on the probable cause, and maybe a solution to it. Helluva mess. I can't afford to waste any more money, so, what's next?

Thanks for you help,
Dan
