DIY cables question


Hello,

I first dipped my toe into hifi during covid and being on a budget, I slowly bought used to build up my system including a decision to DIY my own speaker cables. I bought 20ft of Mogami 3014 wire along with some gold plated banana plug connectors and while having zero soldering experience gave it a go. To date everything works fine but I’m left questioning whether my potentially "shoddy" soldering work is my weakest link and is holding back my setup. I’ve been flip flopping back and forth on just buying some used name brand speaker cables so I can stop the torment. I guess my main question is, when wires work, is it black or white, meaning they either connect or they dont, or can bad soldering limit the max performance of the cables or furthermore my entire setup?

Aside from my DIY speakers cables everything else is name brand, I use AudioQuest Earth RCAs (TT to Pre) and AQ McKenzie XLRs (Pre to Hegel H360), and a Curious USB cable ( Stream Box S2 Ultra to Denafrips Pontus II)

Thanks in advance.

Scorpio43, if you don't have a third hand go to Harbor Freight there $5 and angle tube towards you or level so solder doesn't disappear down tube on you. You can get 3 solder suckers for $10 shipped on amazon. A quality solder iron was also key for me the $50 orange Weller iron didn't work for me. I had to spend $100 on Hako and it changed everything for a beginner like myself. It was almost impossible to melt solder on a Cardas copper binding post with cheap Weller but took a few seconds with Hako iron. Once you have a nice Iron and few necessary tools soldering becomes very easy.

I now instead of selling and buying new gear I first try to add better parts to components and crossovers. Which most of the time stops the need to have a revolving door of audio gear. 




I made a pair with same wire (3104) using pangea ultra somethings...solid quality connector.
Back during the wild CB craze in which everyone who had a CB radio had to pump their power up to grossly illegal levels.  I was just starting my quest for high end audio back then.   My neighbor across the street was one of the those 1KW+ homebrew transmitters.   Needless to say it bled into my system big time.  I kept working with some of the RF engineers at work, as I worked in military avionics back then.   Eventually, I solved the problem - I found some 16 gauge coax wire with a full shield and I used it for my speaker leads.  The 16g center conductor was for the speaker and the shield was tied to earth, so four pieces of coax did the job for the two speakers. It turns out that the CB transmitter power was bleeding into my power amp via the speaker leads.   Since the amplifier output is also the input via feedback, that is how the RF was getting in.   Once I had the speaker wire shielded, it worked fine.   As for the dude with the illegal transmitter, about 6 months later the FCC descended like a hawk and arrested about 200 illegal CB's in the area.   End of problem.
