Need copper speaker cable recommendations $300 ish

Hi everyone.

I know I just asked about copper cables and what it takes to make a good one, but I would also like to know what copper speaker cables around $300 (6-7 ft) are out there worthy of recommending. My setup is on desktop with a coaxial speaker using seas L12RE/XFC driver and a digital integrated amp which is fully digital and do not require a DAC but sounds analogue, have many eq filters that stuns people for its natural sounds just out in S Korea. I have not received the amp yet, but the speaker manufacturer told me that I probably want to avoid silver/hybrid cables as it can make sound harsh on high notes, so high grade copper speaker cables they recommended. What are some good copper speaker cables available in the US? I know OCC coppers are good, Audio Envy SP 9 are great, some Neotech 3004 mk2 variants also good, but that is about it. Thanks a bunch in advance!

There’s a 6ft pair of Acoustic Zen Satoris available here for $425 (about $800 retail).  Great all-around cables — you won’t be disappointed, but if you are, just sell them.  Best of luck. 
How do I separate the left and right? Since this thing looks like it comes with just one red wire unlike all the other diy speaker cable bunch that are thick and comes with at least 2 separate wires in one cables, one red and one black or so. A little confused.
I use a little piece of heat-shrink to add a black marker to each end of one wire of the pair. Then use a larger piece of heat-shrink every six inches to hold the two wires together in a pair. Keep the wire in one direction and try both directions when testing if you want. For a 6' pair, you'll need 24' of wire.
Make your own and spend $600 on something else. For short runs it makes little difference until you're spending 4 figures on both amp and speakers. IMO. YMMV
Mogami 3103 o4 3104 at Redco.
You can get your connectors there as well if you need to solder.
I believe Redco does the 3103 in a "custom cable" if you are not handy with a soldering iron or can't do a bare-end connection on both sides.Mogami is a great value, excellent resolution and very musical.
