Cheapest but good cables….

According to an established member here who’s compared this to higher $$$ cables this is very good…

Here, you can buy 100M of an unterminated flat cable.

Nordost for flat cables but 12ft might be more than you want to part with, if so maybe AudioQuest. Canare for interconnects which BlueJeans sells. If you can keep your speaker cables above the carpet, Canare is a good choice. 

The Micca cables Lak mentions in the above referenced thread are worth try.

I've been running a 6' pair at the computer since mid October, 2022.

It's not a high end  system, but it's a nice sounding nearfield setup.

I've used Kimber 4VS and 4TC speaker cable with the same components in the past and prefer the inexpensive Micca cable.

This was older Kimber (Gray/Black and Blue/Black - I think).

I purchased a 12' pair to try in the living room system, but have to add binding posts to the speaker cabinets before doing so (I currently use 47 Labs OTA cable soldered directly to wide band single drivers).

Just buy the cheapest Morrow ICs that are long enough for your use. They lay flat and are transparent enough.

Flat speaker cables? Nordost. 
Interconnects that you can hid under the rug? Balanced BlueJeans. I actually prefer them to Mogami as they’re slightly more laid back and are less harsh. Mogami Studio Gold XLRs were ok but not great in my system with benchmark dac3 hgc. 

I usually use Mogami too, but I lashed out on some of this:
 

Of course you need to dress the ends yourself… exactly the same as using Mogami.
I think that the Benchmark has SpeakOn connectors??
If so Neutrik SpeakOn is easy, and their stuff is nice to work with.

I am not sure that the cotton is better than Mogami, but it gives you some other option to consider.

I went for cotton as there is no teflon and a lower dielectric constant than the plastic insulation. So I considered it like a po-man’s battery biased AQ speaker cable… Just rather than a battery, I am using a dielectric with does not polarise.

Thanks for that Celtic!

Hard pressed to beat Mogami for cheapest and best.  Here on Audiogon is a small builder doing speaker cables and interconnects with Neutrik connectors.  I ran a pair of his balanced on a 30K pair of active speakers and they rocked.

Or you can order plain speaker wire non-terminated.  

Hey, for less than $3.00/ft. You cannot go wrong.  These run a pair of Mordaunt-Short 10 monitors.

System is Benchmark AHB2 with Benchmark DAC3 preamp. I have Totem 1 bookshelf speakers but may use Paradigm S2V2 after comparing.

Dont have the luxury of testing out different cables - I moved to Brazil and am bringing components here bit by bit. Cables will be about 12 feet maximum.

@thomastrouble   read a couple of posts by member lak in the below linked thread , one of the posts also includes a review video . Maybe these will suit your taste and will satisfy your budget

Cables are system dependent. So, without knowing which speakers you have, its hard to give you any meaningful advice.Also, you should take any such advice with ’two graints of salt’ if its provided by somebody who has not listen the combination of amp/speaker that you have.If you could try cables before buying, it would be best solution for you...perhaps loaning first from some friend or a friendly dealer or from Cable co. Do not hesitate to buy sh product...sometimes, older, discounted top models are worth finding...

Oh, and I’m looking for flexible cables that will lay kind of flat under a carpet. I had an old Naim preamp that could only be used with Naim cables and these were like trying to lay plastic water pipes - stiff and looping - I want to avoid that.
