Cambridge Audio Product Reliability

I have owned a Cambridge Audio AZUR 840C CDP for about 5 years, out of those five, it's been in for warranty repair twice and the last repair was out of warranty at a cost to me of about $300. In each instance, the repairs consisted of failed circuit components, and the last, a toested transport. Bottom line, though a great player I think they must have used cheap parts. I am considering their AZUR flagship IA, but am concerned about quality and reliability, can anyone speak to this, and by that I mean their own experience with Cambridge Amps - Thanks!
