I’ve been wanting to ask as well but didn’t want to be pushy. I like how you asked. 
I love the concept! If it works good it will be a great addition to the Edcor mods!
Hi Vince,
Like to share that the 2 variable dc outputs on the HDPlex are very inferior sounding to the fixed 12 vdc rail, when connected to the analogue PCB.
Never used the 18 vdc either.

Obviously if it didn’t work well we would not be moving forward with this project. Getting parts is the biggest hurdle right now. Should have the first ones built in a couple weeks. I will have more info at that time.

Glad to take the hit for the team Vince! I won’t ask how the power supply adds to the quality. Your turn with the question Vince.

… as in A-B testing? I may have to wait until @jkrichards and EE offspring get parts in a few weeks.
Fortunately, a predicated upcoming tryptophan induced couch coma should help me refrain from asking too soon. 
Do you have a link to that power supply? I googled but could find. Thanks in advance.
I use the high current output rail of HDPLEX 300 on my DSD too. I never tried the other assuming more current is good thing for analog reproduction. Glad to know you found this best

Very cool! Thanks for the picture.
Awesome. I’m sold.
Very cool. Thanks for posting. Will there be an option for female 5.5 dc plug on the device instead of what’s shown in the photo?
No. Them plugs can be pulled out by mistake easily. The connectors we use are held in place by screw-on threads and can handle the power needed. You can make an adapter or cut the 5.5 off and attach the included connector.
The 2-Pin connector we use.

Yes I’d be in I noticed the question marks.
OK. ??? removed.
Thanks!
The relays we will use has Silver Tin Oxide contacts for superior in-rush endurance and sound quality.
Have you got a ball park price for your I presume stuffed? board
I would think one would want to improve upon the cable from the power card to analog board with an improved shielded star quad cable especially internal to the DS DAC to get the best performance. Versus reusing existing. That was one of Ted’s recommended tweaks. Otherwise your leaving improved performance one can achieve both star quad shielded internal and external LPS to the DAC. Versus two conductor DC cables from LPS internal. There really is a performance improvement you can hear doing better cabling
The reused cable is only used to pass power to the analog board only if you don’t use or power on the external power supply. Remember the unit will still work off of the internal power supply if no external power supply is used. The external power supply cable inside the unit is 14AWG 2.4mm OD Silver Plated FEP Wire High Purity OFC Copper Cable. Your welcome to make whatever mods you feel is necessary like supplying you own cables. We are not changing the design for individual needs.
