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. - #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?

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. - #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。

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.
Let us share the joy of DIY practices relating to perfecting the audio performance of hifi system in the pursuit of improved listening experience.
Have a good day. - #2 [hc21924900], 21-11-27 08:34Do it yourself 正正係自作自受,當中的苦與樂,旁人不會明白,更不能用錢去衡量。

分享及推動『自己動手』DIY 文化和實踐,
著重以不胡亂花費的前提下,提升音響系統的水平,達至個人期望。
先來心態的分享:
【半称心】不是无奈和消极,而是一种豁达和智慧。
自古人生最忌满,
半贫半富半自安;
半命半天半机遇,
半取半舍半行善;
半聋半哑半糊涂,
半智半愚半圣贤;
半人半我半自在,
半醒半醉半神仙;
半俗半禅半随缘。
人生一半在于我,
另外一半听自然,一半听Hifi。 - 返回 ...
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.
