Percentage of cable cost

Buconero, I too was naysayer, an open minded skeptic if you will regarding expensive cables...until I tried them. Actually it pisses me off that they DO make a difference...even power cords! I really, really... wanted to draw the line, cut some corners somewhere...but if you have decent separates, they can and will benefit from better cables. As for the % in question, list price of course, if I had paid list, 19%. If I had not got short speaker cables for monoblocks and kept my gear low and in the center it could of easily gone up another 5% of total MSRP. I don't think there is a formula that works for all but it seems like anyone with an optimized system ends up being at 15% on the low side and 25% or more on the high side. Tmsorosk...Don't feel bad I would easily be close to your % had I not used as short as possible runs wherever possible and I'm toying with "interviewing" some $$$ power cords.

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.
