Well, I can tell you that I am on my second potentiometer on my P5 and it's faulty once again. Very upset about it. Almost turns me off of using it anymore.
Yeah, I would not be a happy camper right now either.
This is a real shame because I really like Parasound! I have a 1206 HCA, and a zCD and I have been absolutely happy with both units (both purchased on the used market).
Honestly, I'm a bit surprised that Alps is having QC problems too. Perhaps there is an inherent flaw in that design, or an Alps supplier is slipping up.
Alps pots are ubiquitous in audio and other electronics too. The analog joysticks on the Xbox controllers are actually Alps pots too, and those things must stand some real abuse.
Let us know how it plays out. I think the takeaway right now is to be very cautious with purchasing or recommending Parasound, especially if it has a motorized Alps pot!
