Percentage of cable cost

TEN PERCENT is a good amount of money to spend on cabling.
More than that and you should have just spent the money on better electronics IMO.
Naturally some 'cable crazy' folks think nothing of spending way more on cables. That is their free choice.

But if you want advice, ten percent of system cost is a great way to avoid foolish cable excess.
My entire system audio and video, for interconnects, power cords, and speaker cables, is pretty exactly 10% of total system cost.

My powerline conditioners add another five percent to the equation.

So "IF YOU NEED TO ASK" then ten percent is a great choice.
For folks with a lot of experience knowing what they want and expect from electronics and wires, they can and do, do anything they want, andthose folks may have very different percentages. But, as I mentioned, for a beginner, ten percent is an excellent decision.

I've been studying this for over two decades now, and I've found that the sweet spot for percentage cable cost in relation to system cost comes in between 16.7432% and 18.6559%.
For the sake of everyone's safety, I implore you, DO NOT stray outside of those boundries!!

I've had Kimber 4TC 8TC, Morrow SP3 SP4, now have Nordost Blue Heaven. Like them all, but their no better than Best Buy or Radio Shack. The sound is the SAME! Get over it. If you want to spend money for nothing, go ahead.

To ensure that you have a very high probablity of attaining mediocre sound you'll want to abide by the 10% rule.

To attain superior sound you'll have to think differently.

Ten percent works in my HT but in my analog 2-channel it's closer to twenty five percent.
