RCA interconnect recommendation

Thanks but I'm confused.
some of my components are not over 5k but many are at or close and above.
Is this just an arbitrary rule you apply or does it come from somewhere important? I thank you for your answer but I'd like some thing a bit more directly related to my gear and objective. But thanks

With Rogue gear(ST100 and RP1 or RP5) I had excellent results using Acoustic Zen Matrix Reference 2 and Absolute Copper.

With the integrated I’d probably go with AZ Silver Reference MkII between the phono and Chronus and Matrix MkII for the digital front end.

Audience is also a good match. Older AU24 interconnects should be within your budget. 
I would steer away ffom Cardas unless you’re looking to round the highs.

"The rule of thumb is 10 - 15% of total budget."

Nothing more than markeing nonsense. Sheesh...

I find it a bit odd that someone who owns Weiss and EAR has no idea about interconnects, because they're pretty sophisticated components.  But if you never fooled around with cables, I suggest you buy a couple of pairs of ICs from Blue Jeans for about $30/pair and listen for a few months.  They are good, pro-quality cables and will give you a baseline.  Later on, you can try some higher-priced cables and see if you think they're better. Without a baseline, you have no way to know.  As to the "10% rule", I think that may be good advice when you're purchasing a new system and you're on a tight buget, but I have used expensive cables on cheaper components and found they made a huge improvement.  If you're of a mind to move ahead right now, I would look for a pair of used Audience AU24s, which are great cables for the price.  The older models are excellent and the company has great customer service when you need it.
