I had not tried the earlier stiff DCCA PCs, but have tried the new 2006 REF1. Yes, it is stiff but no more so than many other high-end PCs I've tried. I needed a PC that could bend in a 4" clearance behind the amp and it worked just fine with the new REF1. If you need a *very* flexible PC, you probably need to look elsewhere, but unless you have an extraordinary requirement, the new DCCA PCs are excellent and definitely worth your time. Plus, I agree with Scifi -- talk with Don -- he's a great communicator and will definitely find a way to get you exactly what you're looking for.
Good luck!
