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

@jetter I am very happy with the Teddy Pardo LPS. I began my streaming journey with just the Node (gen 1) a few years ago. I then added an MHDT Orchid DAC (tube on the output stage) to bypass the Node’s internal DAC (using all Silnote Audio cabling). Then a few months ago I upgraded to the newest Node (moved the old one to my 2 pairs of B&W WM6 outdoor patios setup) and then added the Teddy Pardo about 2 weeks ago. I should add I also have a BAT VK600 with bat pack huge, lots of current, fully balanced solid state amp; BAT VK-6i tube preamp; all feeding into my fully upgraded/restored Apogee Acoustics Duetta Signature full range ribbon speakers. 
Now to the sound improvements from the Teddy Pardo…I found the sound stage imaging/separation got even better (wider and deeper), along with bass response and overall delicateness of the notes, if you will. The background noise floor always sounded super quiet, but I suspect it may have dropped even further (dynamics seem to be sharper in a good way). The very recent BluOS support for FLAC files shot it up even further. My reference recordings I use for comparison are centered around Jefferson Airplane’s White Rabbit, Jeff Beck’s Cause We Ended As Lovers, Trentemoller’s Miss You (this is likely my favorite all time cut, I always come back to it), Pearl Jam’s Present Tense and all of Muddy Water’s exceptional album Folk Singer.

I have an Audio Research Reference DAC.  I primarily listen to instrumental jazz.

I primarily listen to Qobuz. Before the Teddy Pardo upgrade, Pandora sounded okay, now Pandora sounds AMAZING!

I suggest getting the Teddy Pardo upgrade...it will be money well spent for the leap in performance upgrade you’ll receive.

Just back and thank you for your detailed responses, it is exactly what I was hoping for.  I am thinking that I have thought long enough and it's time to purchase the LPS and the board that you install in the Node itself.

The very recent BluOS support for FLAC files shot it up even further.

Bluesound has certainly been improving BluOS.

Thanks and Happy Holidays

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.
