External Linear Power Supplies

@jerrybj thanks for your reply. I am using a Swagman Labs SE 18V power supply with my Pro-Ject Tubebox DS phono preamp, and it is excellent.  Based on general positive reviews on forums, I just bought a Teddy Pardo Dual 5V/3A supply to power both my Chord Qutest DAC and my Bluesound Node N130.  I have not installed the DC connection on the Node yet, but connected to the Qutest and with only 50 hours on it, the Pardo power supply is leaps and bounds better than the stock Chord switching supply.  It is not even close, call me impressed.  I am using a PC I built from Furutech parts with Pardo supply, fwiw.

The Teddy Pardo supply is also leaps and bounds better than the switching supply built into the Bluesound Node.  My digital front end has now been improved across the board by adding the Pardo supply.  Tighter bass, more detail across the frequencies, better attack and decay, more organic and natural sounding overall, and sibilance has been banished.   I cannot really say enough good things about my experience with the dual 5V supply from Teddy Pardo.

@analoguefan How's the Zero Zone LPS going so far?  Does it get hot to the touch?  I'm interested in getting one for my streamer as well since the price looks reasonable.  Can you link which model you got?

@scslite 

I know a few guys that have had good success with a Zero Zone 01-A

@jerrybj Thanks for the link.  Looks like my current SMPS is 12v 5amp.  Will this be too low on max current at 4amps or is sufficient?
