Question 3 into 2 won't go?

[thedoc735]

Can the HDPLEX.HiFi.500W.DC-ATX.Converter with the 3 pin (DELL) socket (7.4 x 5.5mm) be used with a 2 pin plug that is attached to a linear power supply unit?
If yes(?) - what is the pinout/wiring arrangement?

I did try a 5.5 x 2.1mm jack plug with the :
white positive wire to centre pin (inner barrel ring) &
black wire to negative outer barrel ring;
blue (data) wire not attached, i.e. only negative and positive from my 12 volt LPSU. But it didn't work and just got a red blinking light on the motherboard? HDPLEX voltage input does NOT have a data wire/channel! Only +/-. So in effect I tried to ignore the blue wire, hoping that +/- would be sufficient? HDPLEX cannot 'read' the blue data wire, or so I thought?

and you'll see the adapter you're told to pair with your HDPlex unit.

You need this adapter.

Yes I know it is supposed to have the SMPS (brick), but I was hoping I could use a sound superior LPSU, due to DC switching ripple current, i.e. LPSU makes the ripple noise LESS noticeable.
I wanted to use the the HDPLEX.HiFi.500W.DC-ATX.Converter with a LPSU (with only +/- pins). e.g. https://www.mcru.co.uk/product/linear-power-supply-for-music-servers-streamers/?v=79cba1185463
This is for Hi-Fi.
Or is this simply NOT an option with the hdplex 500 converter?

Well, there is always this instead of LPSU: (?)

Gallium nitride (GaN) is a technology that's becoming popular in high-fidelity (hi-fi) audio systems because it can deliver high-quality sound with exceptional efficiency. GaN's benefits include:

• High-fidelity sound
  GaN's fast switching speeds allow for precise pulse-width modulation, which results in accurate audio signal reproduction.
  
  
  
• Efficiency
  GaN's low on-state resistance and reduced power losses make it more energy efficient than other technologies.
  
  
  
• Compact size
  GaN's efficiency and smooth switching characteristics allow for smaller, more compact audio systems.
  
  
  
• Reduced heat
  GaN's reduced power losses and heat generation mean there's less need for large heatsinks.
  
  
  
• Better sound quality
  GaN's high-frequency operation results in a cleaner and more accurate signal.
  
  

GaN is used in a variety of audio applications, including:

• Stand-alone audio amplifiers
  GaN's high switching speed, low on-resistance, and high breakdown voltage make it ideal for Class-D audio amplifiers.
• Active loudspeakers
  GaN can be used in the power stages of active loudspeakers to create smaller, lighter, and more efficient systems.
• Portable audio systems
  GaN can be used in the power management circuitry of portable audio devices to improve audio quality and extend battery life.
• Automotive audio systems
  GaN can be used in the power stages of automotive audio systems to improve efficiency and increase output power.
