Need recommendations for 20' speaker cable

When I first moved in my place years ago, my speakers fired down the long wall in a rectangular room. The speakers were 5 ft out from the front wall and the rear wall was 12 ft behind my listening seat. My amplifier was between the speakers so the standard 10 ft run of cable was sufficient.

Currently the system is turned 90° and as shown in my Virtual System pics, the speakers fire down the short wall with my listening seat directly at the rear wall.

Out of curiosity, I purchased a 100 ft spool of generic speaker cable and moved my speakers to their old location. I knew this would happen but I immediately got more depth, more separation of instruments. More localization of musicians, etc.

I don't want to move my rack so if I keep it this way I'm going to need 20 ft of speaker cables. The fact that I now use monitors and the terminals are 2 ft off of the floor only worsens the situation regarding length.

So, long story long, I'm looking for recommendations on 20 ft speaker cables preferably under $1,000 new or used.

Thanks.

So another issue has arisen...

My zip cord is 16 gauge and 20' long. 
When I put my hands on the sides of my class A amplifier, I THINK the heat sinks feel warmer than before.
Before I could hold my hands on the sides of my amplifier for 10, 15, 20 seconds without having to remove them. Yes it was  hot, but it was tolerable.
Now, after 5 seconds I think it's a bit warmer and I don't remember it being this hot. I could be wrong. I could just be getting inside my own head but I'm wondering if the added length and the thinner gauge of the zip cord could be a factor in my PERCEIVED increased temperature.

I have to agree not to worry about arbitrarily short runs. I have always worried about them but never actually heard a difference.
.
One thing that my trusted audio guy (30+ years) recommended was doing the long run between preamp and amp instead of speakers and amp. Then if I got dual mono amps use really short < less than a meter cables. He said this gets you some real advantage in frequency timing (?) or something like that. I did not go with monoblocks, so didn’t pursue understanding the advantage. If I upgrade to monoblocks I’ll revisit it. I trust him... he has implemented probably a hundred high end systems. These kind of advantages are not likely to be heard in systems < $50K, which always has to be one of the considerations. What level of performance are you at, and going to be, and when?

Can anyone tell the difference in a blind test, between a 10-ft speaker cable and a 20-ft speaker cable?

So let me get this straight. When someone hears it you cast doubt and demand double-blind proof. But when it feels warm that is okay, no need for a double-blind there.

One double you are consistent about: double standards.

Lmao! Good one. Ok, just chill ’carbon.
My original question was if one could HEAR an audible difference between 10’ and 20’ length of the same cable.
But I was wondering if the PERCEIVED temperature change could have something to do with the gauge of the new cable.

Good observation though.

Isn‘ this ultimately a function of the construction of the cable? There are vast differences between single core, litz, twisted pair and shielded vs unshielded cables in terms of resistance and more importantly capacitance. While generally shorter is better, a low capacitance cable running 30‘ is not going to give problems, in any case less so than an equivalent run of RCAs running to feed monoblocks given the significantly higher voltage from the amp.
