I talk a lot of people into buying Denon Prime Gear, so I also get phone calls, messages, and e-mails when issues arise. Most are user error related, so talking them through it is easy enough. However, I have received more than a dozen hardware related issues on the Prime4. Mainly 1 side will become unresponsive or the unit freezing after startup. Replacing the Prime4 always ends up being the solution to fix the problem.
My question, was there a bad run of Prime4’s that went out to market? If so, is there a way to easily identify the defective units via serial number?
