Just terminate the cables and screw them tight..

I always use solder (BWT currently) to finalize cable ends.
Never used any sleeves till now.
BTW, for correct sleeve installation you need to use special crimp-pliers.
I do not have it yet....
You don't need a crimper.

A close fitting thimble over the stranded wire ends will be crimped when the screw terminal is turned down hard.

The cross-sectional area of the thimble will be bigger than the cross-sectional area of the cable. That equals lot's of air/gas between the wires.
Screw down on the thimble and the area inside the squashed oval is less than the circular cross-section. Screw down hard and the kidney shaped cross-section inside the deformed thimble is now less than the cable cross-sectional area. The wires get deformed and you end up with "gas tight" joints between the strands and between the thimble and the wires and between the thimble and the enclosing terminal.

It's the "gas tight" that gives the excellent long term electrical connection.

And a thimble replaces the need for soldered ends and is FAR BETTER than soldered ends.
I don't have any thimbles. I wish I did have a range for all my cable sizes. I would use them.

As there is a discussion about silent components here I wonder if anyone has suggestions on a quite resistor in the 200-250K range. I find only bulk foils up to 100K. (Anode load for 12AX7 so a bit OT but applicable on the subject maybe)

metal film is very good.
Not quite at the lowest levels of an extruded metal, but very close.

Extruded metal includes foil and wire and similar.

Would you share the links to these vendors? I'm waiting for C3/C4, 2sk170bl's, trafos, Welwyn 0,1% resistors and Vishay VAR's for RIAA and R1/R14. Then a test in free air and decide boxing...

Excellent resistors, I have used such many times. Clean and no harshness. Analog_sa has like those on his loading positions Rx in FSP he showed if you look carefully but in 0.25W maybe 15ppm version RCY.

Boards are now ready for powering up!
I used polystyrene ERO kp1834 5% for the treble RIAA cap plus trim cap which gave me a value of 15.18nf and 15.15nf. Readings where taken with a very cheap DMM so i know that are not accurate. If the sound is weird i will replace them with mkp1837 caps as per guide. The smd resistors are TNPW and r13 is Royalohm 1% 2w MF 50ppm. Output cap is JB JFX which are a pleasant surprise considering the fact that they are really cheap. I tried these as coupling caps in my AD1865 dac, and they outperformed Mundorf white MCap, Solen and Κ73-16. So until i can afford Mundorf supreme these caps will suffice.

Hoping of listening to music this night and not debugging!

You probably got one of the most imaginative mix of components there. Looks well done also. Happy testing and let us know.

P.S. That is the 43dB setting, yes?
