Peachtree iDac reliabilty?

First off, the iDac in my system is a pretty amazing piece of gear. It brings digital to life like I've never heard. Up till purchasing the iDac, I never considered myself much of a digital person. Sonically it's a terrific step in the right direction. I purchased the iDac in February 2011. It worked beautifully, then conked out after 3 days. The good folks at Music Direct replaced the unit immediately. I even had a very nice chat with David Solomon of Peachtree. He's a good guy and very sincere about his company. The 2nd iDac worked flawlessly for 2 months and like the first one quit working. I've now sent it to Peachtree to be repaired. Has anyone experienced a similar reliablility issue with the iDac or am I just snakebit.
