Share with you excerpts from wiki, as follows
The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities.[3] The phrase "do it yourself" had come into common usage (in standard English) by the 1950s,[4] in reference to the emergence of a trend of people undertaking home improvement and various other small craft and construction projects as both a creative-recreational and cost-saving activity.
Subsequently, the term DIY has taken on a broader meaning that covers a wide range of skill sets. DIY has been described as a "self-made-culture"; one of designing, creating, customizing and repairing items or things without any special training. DIY has grown to become a social concept with people sharing ideas, designs, techniques, methods and finished projects with one another either online or in person.
DIY can be seen as a cultural reaction in modern technological society to increasing academic specialization and economic specialization which brings people into contact with only a tiny focus area within the larger context, positioning DIY as a venue for holistic engagement. DIY ethic is the ethic of self-sufficiency through completing tasks without the aid of a paid expert. The DIY ethic promotes the idea that anyone is capable of performing a variety of tasks rather than relying on paid specialists.

- #4 [DYreal], 21-11-27 09:23師兄我都好有興趣想知道你啲DIY訊號線是否有獨特嘅自家技術,定係純粹係一啲舊線加個插頭。
有冇咩心得或者自我理論,線材嘅音效特性會係點係?純粹想交流別無他意。

90年代始,我開始用編織手法做線自用,堅持不胡亂花費,玩音響不純粹是金錢玩意,是一個漸進的過程,也是培養個人對音樂和音效的感知和欣賞能力,算得上是一種素養吧。
當時,主要用西電,有布線,漆皮線等,至今仍保留著一批!後來一段時間,比較傾向採用英國和德國線材。經對比後,覺得新線不如舊線,這只是在我的音響系統以及我所追求的聽感所得的個人感受而已,並無他意。
DIY 過程中,我比較喜歡編織法,也曾嘗試編織再套上屏蔽網,但總是覺得加網後,活潑、彈跳、空氣、活力感都有所下降。目前我的自用接線,都沒網的。我沒有儀器測度,純粹是耳仔收貨,見諒。再者,這只是個人經驗分享,不是嚴格的科研報告。
Allow me to text in English which is more convenient.
I then attempted to use a, wide range of cables from single core to multistrand, from telephone cable to lan cable, flat cable.. etc, the results were impressive and a few outstanding. I trust that the way of braiding is central to the output sound stage.
About braiding, I particularly have a strong appeal to 4-strand braiding which I usually refer to as 3D braiding.
Will take time to share my DIY practices here.
Thank you and have a nice weekend. - #6 [ckhung], 21-11-27 17:25十分認同Leung sir的理諗. 我岩岩整左兩對雙絞線, 用Gotham 14AWG七芯銅線做, 諗住用黎DIY換後級PCB輸出喇叭線接柱果兩對線, 原裝的是一條16AWG多股散心鍍錫銅線, 希望令到D聲冇咁緊, 請教唔知從線材構造上黎講是否應有幫助?

Hi there, I am delighted to share my view regarding your DIY practice for your consideration, and I highly regard your initiative of upgrading the connection between the PCB and output terminals.
About cables , let's make some bold statements: "The best cable is No cable. The Ideal cable, if ever exists, does NOT change the signal traveling through it in ANY way. No cable can improve the sound quality of a system, they only make it worse or less worse in varying degrees."
The above commentaries are made with an assumption that the speakers are being positioned to produce optimal audio stage. At times, changing the listening position has even more dramatic effect.
I think you made a right choice of cables you mentioned and it definitely contributes to enhance the performance of the system, given reasonable burn-in time.
Also, you demonstrated impressive craftmanship.
Finally, I would add that, apparently, the English prefer solid copper conductor whereas Americans prefer stranded copper to connect to speaker output sockets. - #8 [LeungSir], 21-11-27 21:31
Need to add that:
Amongst the numerous parameters that may impact the performance of the speakers, like resistance, impedance , inductance and capacitance of the speaker cables, i think the total resistance of the cables should merit prior attention.
In general, resistance starts to have a noticeable effect on the performance of a speaker when resistance is greater than 5% of the speaker’s impedance.
Enjoy the listening experience brought along with DIY practices. - #9 [hc21924900], 21-11-27 22:22“No cable can improve the sound quality of a system, they only make it worse or less worse in varying degrees."
Agreed - #10 [LeungSir], 21-12-11 10:36
There is no secret about my DIY Berlin RCA interconnect cables. However, I will attribute the amazingly wonderful audio image the cables manage to convey to four key factors:
1. the adorable pure quality of virgin copper wires of the 1960 era made in Germany ;
2.the way the copper wires are being braided into a cable;
3.the configuration of having more negative wires than the positive; and
4.the soldering method to enable direct access / contact of the positive terminal of the cable to reach the target destination.
The photo enclosed herewith illustrates the braiding of 8 strands of wires into a cable of 2 positive & 6 negative interconnect a cable, which is designated as "2+6" .
Finally, I would add that there is always an optimal length of the RCA cable in order to attain quality audio performance while the presumptive idea that "the shorter the better" may not be valid.
Audiophiles may take the initiative to try making RCA cables with readily available wires like those obtained from telephone / lan cables. It simply is fun especially when auditioning one's DIY handcraft cable.
Have a nice weekend. - #11 [rcywong], 21-12-11 11:03DIY cable is fun indeed, no matter the result is good or not, it is an enjoyment. Ha...ha.
Add oil to Mr. Leung - #12 [LeungSir], 21-12-20 14:38
Recent discussions with Audiophiles on DIY cables including interconnect cables, speaker cables and power cables confirm repeatedly that braiding the strands of wire contributes to better sound staging in terms of the enhanced extent of clarity and richness on details along with a, wider and deeper audio image.
Try braided DIY cables. You will not be disappointed. - #13 [LeungSir], 21-12-26 11:47
學習袁隆平「中國雜交水稻」的經驗,
制作雜交電源線,果然帶來預期的音效提升,
用料是來自兩個不同生產地的Neumann 混合線材,
以四股立體編織,L and N 各四條,兩兩混合,
造4+4+1電源線,音色表現,能量和細緻度各方面均有明顯提升,值得一試。 - #14 [LeungSir], 22-01-02 10:37
There are ways to braid 4 strands of wires, namely the round braiding or 3D braiding.
The following video vividly demonstrates how a 3D braiding is done.
One can apply the braiding to make RCA or speaker or power cables.
Many of my "audio acquaintances" share the joy of DIY cables.
Have a nice day and fun with DIY interconnect cables. - #15 [geotyc], 22-01-02 11:06Leung Sir Ching,
Happy New Year!
Tks for your sharing on diy cables! I have been following your advice and did some braiding. It's fun!
I'd like to ask n seek your opinion on adding metal shielding in the braided cable. Some people emphasize that shielding can do more benefits to get a silence background. Would there be other factors?
Hear from you! ?? - #16 [LeungSir], 22-01-08 10:26Hi there, I share your idea of adding a shield to interconnect cables to screen off EMI interference for a "darker " or quieter audio background.
However, such an arrangement may not always work 100% as expected without any drawbacks.
For braided cables like the ones I am advocating, adding a shield to braided cables may weaken the performance of the cables in terms of agility, 空氣感,彈跳力,活潑感,以及具血肉的質感, although at times a negligibly quieter background is achieved.
Regular braiding pattern itself is a commendable means to do away EMI interference and is the best economical method to achieve transmitting pure audio signal without loss of agility. It is highly regarded by a 攝影和音響前輩李祖斌大師。

Frankly speaking, I am not an audio specialist, nor in possession of some profound knowledge of making audio interconnect cables.
But I have accumulated lots of experiences of making DIY interconnect cables over twenty plus years of practices, using whatever cables I came across, including even the cable connecting the mouse to a computer.
I take pride in the Berlin RCA cables I am advocating, which, as concurred by many many users, have been well received and highly regarded by all of them.
這可能是『天道酬勤』that I came across the Berlin cables during a business trip there some twenty years, ago. It is, by all means, a luck.
There is no secret to my DIY Berlin RCA cables. It is just the pure copper wire of the 1960 era that matters. Also, the braiding method plays a pivotal role.
I did try, a number of times, to apply a shielding to my Berlin cables. Yet the efforts were in vain, yielding no improvements in the resulting audio performance. - #18 [Office], 22-01-10 15:36I have been using Mr Leung's cable for 2 years, during the time various experiment have been conducted under different plugs, soldering materials and braiding construction. Unfortunately there is no universal application for best result, everything correlate with each others such as what was the gear and where to apply and which materials were utilized (i.e plugs), one important factor which is individual preference.
In one occasion, needless to say the time had spent, I had to dissemble Mr Leung's cable completely because the sound was so BAD, what I found out it was not a fault of the cable, indeed, it was a wrong technique was being applied, IMHO "braiding" plays a crucial role for every berlin cable, difference is night and day, not just braided but make sure to braid it correctly.
To DIY a cable that suitable for one's needs, this is where the fun and hard part begins, berlin cable has such potential to make it happen.

Recently, I made a pair of XLR interconnect with Berlin copper cables, deploying 2 for hot, 2 for cold, and 4 for earth and all 8 strands of cables are weaved together with 3D braiding.
The resulting audio performance is simply amazing and well received by audiophiles. DIY is fun. You should try it with, say, lan cables.
The central issue is 3D braiding, believe it or not.
