For what it's worth, Bluesound instructions noted to keep the Node on all the time as the power up cycles can increase wear and tear on components.
Should You Leave An External Power Supply On 24-7?
I had always left my Bluesound Node on 24/7. I have recently installed a Teddy Pardo external linear power supply on the Bluesound Node. Is it wise to turn off the power supply every night when I shut the system down, or should it be left on 24/7?
Your thoughts please.
