Should You Leave An External Power Supply On 24-7?

@jetter 

Assuming you use your nodes with an external DAC, what is your objective opinion on how much adding the LPS improved the sound? 

NODE 130 with external DAC here. I added the LHY LPS (under $300) and it made a significant difference. And that was before I added the DAC. Bargain upgrade.

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.

There is no way to turn it off unless you unplug it anyway.
