I just thought I'd ask. I figured if anyone had a line on a DC plug of better quality, it would be you.
I'm planning on hard-wiring mine at the power supply end, using 18 ga. silver plated Teflon wire. The quiescent draw of the Slee phono stage is 30 mA @ 24 VDC, so even 18 gauge is serious overkill.
I'd like to hard-wire the Slee end too, but will have to see if I can bypass the DC input jack without ruining it. I have no plans to sell it, but you never know.

a little DIY is needed but there is no comparison with the usual dc power plugs that in some cases are very poor quality.
Why to spend big money on a connector inferior by design when you can have exceptional connectors for almost nothing ?
Kind regards,

"Does not ship to United States" according to the ebay listing. That means I can't get them.
Thanks for making me aware of them though. Perhaps I can find another source.

Guess I should have Googled before I posted. It looks like I can get five pair of the XT60s for $3.80, and free shipping.
Thanks for making me aware of these, beppe61!

The XT60 appears to be an inline connector -- a quick-disconnect butt joint connector.
There's no XT60 jack I can find that can be installed on the chassis of a power supply or component.
While the gold plated contacts look very nice, an XT60 connector won't work for a DIY DC umbilical project.
See link:
It will work, but it's going to require more work. The chassis mounted jack would have to be removed, and a short umbilical would have to be added, along with strain relief.
Is it worth it? I guess it depends on whether it is believed (via listening), or could be proven (with a scope) that the XT60 is somehow adds less noise to the DC you're feeding in than a standard DC jack and plug. I've give it some thought, and I don't think I'll be reworking a $1200 phono stage just to find out. I'm going to stick with the CCTV type plug you recommended, and leave the jack alone.
Thanks again.

Your thinking is reasonable regarding an otherwise captive DC umbilical, with an XT60 quick-disconnect mounted inline in order to separate the PSU from the component without using chassis-mount jacks. However, that approach would negate the ability to swap-out DC umbilical cords.
I finished the DIY 16 AWG mil-spec DC umbilical project today. SPC/PTFE Teflon mil-spec wire implemented for DC applications takes ages to burn-in, so it will be a while before I can post a proper report. However, I can say at this early stage there are sonic aspects that are definitely more impressive than what the stock 18 AWG PVC DC umbilical provides. This is no real surprise, since I've built seven DIY mil-spec DC umbilicals over the years, and none of them were disappointing after ample burn-in time. I had as much fun as ever building this one as I had with any other one I've built. I'll post information with special tips about the DIY mil-spec DC umbilical project sometime down the road.
The CCTV DC plug is an excellent professional installation connector. Good build quality, and the tiny termination slots with set-screws are similar to AC plug termination slots. The small clamping mechanism actually provides a very solid grip if you use a good quality small screw driver for the task. The 16 AWG mil-spec wires fit perfectly into the slots. It's about as good as it gets if you seek a solderless DC connector, and I would definitely choose it again over a typical narrow barrel DC plug. That said, I'd still like to know how much better the premium Oyaide DC plug might perform.
The "XT60 Bullet Connectors Plugs" were designed for R/C = radio controlled cars, boats, planes, ect. to connect lipo battery packs to the Speed Controllers, they are not audio quality connectors. The gold plating will flake off the connectors quickly. I know this because (i have used the XT60 plugs) i am into R/C big time and there are better plugs for R/C then the XT60 connectors.~D

Hi and you are welcome !
They are recommended for low voltage high current applications, but i guess they should be ok also for lower currents. The execution of contacts looks pretty good and much better than common dc plugs.
And they are quite affordable also.
Kind regards,

The Oyaide DC-2.1G and Oyaide DC-2.5G are the nicest DC plugs I've come across, but the design has the same issue of being a narrow barrel type connector. It's unknown whether or not the premium Oyaide connector would be worth its price point for my particular application.
