Can I do any better than BJC LC-1 or Gotham GAC-1 Ultra Pro for the money?

When asking about wires it is nice to have a point of reference otherwise the advise you get will be rather generic for you. BJ's is a good cheap cable, IC's or speaker, but does have a sonic signature. Its not razor sharp likes some others which are highly regarded (or condemned) by some folks. What I like to suggest is that you waste a few bucks to see just how much you can hear the difference between two cables/IC's and if you can hear the difference it might point you in the direction you should go with your whole system. You might get a 2 meter BJC L1  and a 2 meter WBC Mogami 2549 and listen to them. They are both good quality cheap cables but with a distinct sonic signature. If you can't hear the difference don't waste money on cables at this point in your audio trip. If you can hear a difference you can choose, or at least get recommendations for cables with a similar signature.

Here are a couple pairs of Acoustic Zen interconnects at an attractive price that may punch above the bargain basement stuff. Owner says they approach the performance of AZ’s much pricier interconnects, and if that’s the case I think they’re well worth a try. At $325 for two pairs it’s pretty low risk, and you can always turn around and sell them for little/no loss if they’re not superior to others in your system. Just another option, and best of luck.

@newbee , shouldnt I be able to measure it, say like in REW, if I can hear the differences between them?
I do have other RCA like, Onix from Monoprice, and RiCables (probably the most expensive ones I have), some old Monster stuff, etc.

@soix, unfortunately $325 is not even close to the price of the ones I mentioned though plus I will need 11 cables (7 at about 5’ and 4 at 2.5’)

Got it.  Well, you could buy one of the AZ interconnects for only about $165 for the arguably more important connection from pre to amp and go cheaper for the Atmos connections.  Just a thought FWIW.
