Yashu, I would call Kal at ARC customer service. But I think the instruction manual or a packing insert would tell you what the break-in period is. Most of their new gear requires 600 hours. If that is the same with the CD-9, it's way too early to make any judgments.
I own the Ref 5 SE and Ref 150. My Ref 5 was upgraded at the factory to the SE version. I was told it would take 300 hours for break-in. I think it was more like 600 hours. The Ref 5 SE sounds great. I'm sure you will be equally pleased with the CD-9. I can tell you this -- the CD-8, which I also own, is a terrific CDP. I gotta believe that the CD-9 is even better.
The only reason I suggested you might want to call Kal is that I don't know whether it's a good idea (or not) to run the unit continuously to rack up the 600 hours. I kinda think it would be ok, but I'm just a regular consumer like you -- not an ARC tech rep.
