@moee79 , cable 053 silver is like brown copper color. they both are ok, it's just i get noticeable better sound quality (better detail, more accurate texture, cleaner sound, more rounded overall sensation) with the more expensive cables, when listening to very good resolving iems, like moondrop blessing. if you use not very resolving iems, the difference is minimal compared to price difference. there are many cables below $30 with great conductivity. check my list, and then, their links at spoilers (you'll find them at spoilers 2 and 3). @candlejack , i've checked microphonics of cables 165 and 168 (and some others). iems over the ear, chin slider at my back, no music, tapped the cable with one nail. if acrolink cables microphonics is 3, and cable 054 is 1, microphonics of 165/168 is 2, like cables 125/128. i.e., not so microphonics than acrolink, but higher than the most flexible cables. anyway, when playing music, i can't hear any tap on any of them. if you are so sensitive to microphonics, better forget 165/168, despite of the highest quality of their mmcx plugs, and of the high sound quality of 165. you need to aim to very soft cables, like cable 140 (better sound quality than 054).
