amphenols
they are not cheap and only come in two major configs.. 3+1 and 6+1 (they always mark one pin as ground, but that pins is the same size as the other ones, so you can use it like any other pin)
the 3+1 is screwed based and 6+1 is solder based..
I use both and they are built the same way, have the same cut out.. so I don't have to worry about having two different templates

I thought they might be. the amphenols arent too bad, except for the ones i'm looking at, the ones with the really high current radsok pins and army green cadmium plate. the Cannons are just plain awesome!!. see i'm looking at the high current 10 pin (8 high current and 2 lower current for LEDs softstart, control etc) and i need 2 umbilicals, one for each 2 channel (4 phase) amp box. so i'm looking at roughly 350-400 plus wire. the other option is powercons and speakons but use more of them, but they arent nearly as cool
I actually drool over Lemo connectors - but I guess that's something I should discuss with my shrink..
large lemo high current umbilicals? yeah me too, but i dont even consider those as i could buy a small car with the price i'd pay for using those in this project (300 each), i use lemos for all my low level signal and headphone connections though, superb!!
so I bought some amphenols that were used by the US military in their tanks.. and I had to sign like multiple documents saying I won't export them.. they were silver plated radsok pins and super high current capable.. I am saving those for my burning amp builds..
since this is "only" a ck2iii i figure the plastic amphenols is "good enough"
i was going to use speakon etc.. but then too many people going that route and i don't want people trying to connect their speakers to my amp's power input or worst.. the power supply output!

yeah ive seen them before there, but just like the cannon and amphenols its only useful if you have a set that needs a couple pieces or a spare, because they never have a full set of everything, as in 2 female or a male and female panel mount with 2 matching cable connectors, so a 4 connector set and thats the minimum you need unles its just for a single headphone cable and you only have one headphone, because most are old models
if you have the time to wait, start to stockpile the different parts and you should come up with a set.. i have a full metal set that is laying around if you want to buy it from me
I have internal pics.. I will post when I get home in a few days.. it sounds very nice, it is very sensitive to noise I find..
you would have to check with amb forum..

Finished my Ck3 during holidays
Here is my CK3 finished during these holidays. Output stage is not BJT but with IRFZ24n and IRF9Z34n, mods are suggested by Ti Kan for this MOSFET output stage. Case is from eBay, seller is along1986090. Case is great for the price, esp the front panel around 1/4inch thick.
Sound is amazing from my AudioTechnica ATH-M40fs. I also used this as a preamp with 100+100 ohm resistor divider in the output to reduce the gain for amplifier hookup. It is greater even as a preamp driving my Luxman M-4000 amp. Cannot stop listening to this setup, even my wife also certifies this.
These pictures are from my phone, will post better pictures later.

Hi Joe,
Yes it is the protection circuit, since this headphone amp is directly coupled I used this circuit to save my headphones in case the circuit malfunctions. I got this one from the same vendor. This circuit works for 9v I need to recompute some resistors to make it work with my transformer which 16v.

For a budget PS-amp umbilical these SRCN series by JAE from digikey have been reliable for me, my cord making skill is sloppy but you get the idea:
