Affordable cables

You are wrong there Steve. My simple diy ic`s are cheap but I can guarantee that you`ll never find anything better, they are perfectly clean. Only loss will be in the connections. 

I do not have a super expensive reference audio system, or golden ears, and I cannot argue which cable is objectively “best” but this i can say....on the advice of others, i went with Blue Jeans LC-1 interconnects and I am very pleased all the way around.

They have a very low capacitance rating (greatly desirable esp. for turntables), robust shielding and heavy duty connectors. A basic 2’ pair is around $32 but you can get any length you like.

The sound is a huge upgrade over my previous RCAs and I think their products are a tremendous value. As the old saying goes, they’re “all balls, and no bullshit”. For its price, I’m not sure you can do better unless you DIY

I have all bluejean cables but I was curious about others.

When I started , I was very cynical of costly speaker cables. Then I heard the difference they made in a system.  

I started with Dick Smith's finest speaker cable, around $4.50/m (similar to Radio Shack?)
The difference was significant. And have been updating ever since.

I went to Merlin Chopin interconnects to tone down a bright Plinius pre/power amp. Didn't realise part of the problem was the QED Silver Anniversary speaker cables I was using. Then progressed up to Merlin Verdi, and Merlin Vivaldi.

Now on Mad Scientist Nitro Nano power cables, and Audience AU24SX interconnects. Most probably my last.
Can't replace the in-wall Merlin Scorpion speaker cables.

Several companies can assemble what you need:

Speaker cable = Canare 4S11
Interconnects = Mogami 2534

The music you are listening to was likely recorded utilizing one of the above in the recording studio.
