How much durability is needed for something to sit on a hifi rack in a dry room? The demands are obviously much higher for pro gear that gets tossed about, or at the very least rewired regularly. Oddly enough, such gear is typically much cheaper than audiophile brands. Guess it's not durability you're paying for after all.
Well, I had an AVR once that just out of the blue when I pressed the power button, went pop! It had "broken ". It was an NAD. That happened about 15 or 16 years ago. The cost of repair was prohibitive.
I had not one but two NAD CD players. Both of these came to their demise when out of the blue their CD trays wouldn't open.
Evidently, these pieces didn't have enough durability to sit in a hifi rack in a dry room and perform their duties. My guess is cost cutting led to the unreliable/non-durable products.
