True... but then what kind of product these days can't be switched on/off via remote or at least on the front of the unit?
Just switch the entire rack off.
There is no difference between using the switch at the rear or pulling the plug.
Ive been running mine 24/7 with the display off, ive forgotten its even on, i will report back if it fails but you can look at 2 sides of advice here, one says repeated on/off can cause premature failure and therefore will last longer leaving it on, the other side is the opposite. I have tried both methods with my TV, I put it in standby for 2 years until the power supply failed big style tripping the RCD, I replaced the power supply and put it on a remote switch that cut power, this didnt last 2 years and the failure was less severe, it was a dry joint that I found and repaired as the power supply is no longer available. I know its no scientific proof that one way is better but I install electronics in peoples homes as part of my job and some stuff lasts and some stuff doesnt, seems like its the luck of the draw these days unless you buy something built and priced to last.
