Hi, this is a great sounding speaker system! Unfortunately mine is kaput, possibly due to killer voltage spike (forgot to run through AVR). I'd very much like to repair it but I don't know where to get replacement parts. Do these exist at all? I write from the Philippines so shipping the components would be prohibitive. Much better if I could buy parts from somewhere and have these sent to me. I'd really like to keep using this model. It's one of the best sounding I've ever experienced!
