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

@dr-boop I didn’t know that, great info. TYVM  I have a BSN + LPS and leave them powered on all the time.  The combo draws very little current.  I've had no issues doing this.

I never turn my DAC, N130 or my Teddy Pardo off.

ok, now that most seem to agree power supplies can be left on 24/7/365.

if OK, What about a power supply that powers a phono amp with a tube? I would think that should be turned off!  If left on, wouldn't that lead to premature failure of the tube?

Update Class A off. Tubes off. The rest on.

I have a node 2i which I enjoy the heck out of with my external DAC.

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