Order of importance and budget percentages

I focused on components first then cables.

a wire with gain… 😍

I would forget buying piecemeal and split the budget 15% room treatments, 10% power conditioner, 25% for source (s) and 50% on active speaker system like the KEK LS60, the Devilet Phantoms, the Dynaudio Focus XD series, etc.

That certainly cuts out many of the cables.

Components first (seems you’ve got that covered), room next. 
Then…power conditioner for your source, power cord for the conditioner, power cord for the amp, speaker cables next. Interconnects, USB, ethernet. 
Get the best you can even if it is gradually one cable at a time. I’m not inclined to set budget limit of percentage of the component cost as I don’t adhere to any of these guidelines in my system. Get used from reputable sellers.
