Hold on there partner. I hate to say it but that cable you linked to. I bought a similar type cable a long time ago claiming it was gold plated only to get a gold spray painted colored copper cable. Funny thing is it looks exactly like real gold. I am gonna doubt that actually has real gold in there. I wish there exists a real gold plated cable for that much.
As far as I know the cheapest real gold plated cable is the ISN GC4 and those cost almost the same as the Penon GS849. Penon sells a higher purity gold cable which also happens to be their most expensive called the Golden Armour an 8 core pure silver plated in 24K gold for a cool $800. I cant imagine what that ends up sounding like on some IEMS. That being said
Penon stuff I can trust and they charge a reasonable price on their cables compared to other boutique cable makers. You can read the many others that have tried the GS849 cable and you wont see a disappointed person. As far as sound goes. That cable does not brighten sonics in fact it is more closer to copper properties than silver or gold. The bulk being 68% OCC. The reason I chose the Blessing 2 for the first pairing for that cable was because of just how great that cable sounds on the Blessing 2. It doesn't exaggerate but more so expand upon the sonic foundation of the Blessing2. It sounds great on just about everything I tired it on but the Blessing 2 sounds like a new earphone with that cable and much higher end. Anyway I will just leave it at that.
In other news I haven't gotten my NiceHCK silver cables yet but a good buddy just got them and tried them on his Orbs. Says it sounds good on it which if it is pure silver should be a great bang for buck for the Orbs. Will report as soon as I get my set.
I never actually believed that it's a good gold-plating. Good gold plating is not cheap, but when I bought it while ago it was about $22 - too good to be true, but it looked good and I thought that if I don't hear the difference, - will take it apart at work (QA dept, so I have access to some fine equipment), and write about it to have some fun. Like I said before, I call it curiosity budget - part of the hobby.
But then I didn't really knew what to expect. I have dozens of cables, because as you mentioned in your review - very often synergy is more important than anything (given that cable is not defective). I have my own experience of IEMs failing to sound better with expensive cables, only to find their Synergy with $8 or $20 cheapness. Exception- $60 FiiO balanced SPC, that somehow sounds better with FH5 than the stock one.
So, going back to these "GPC cables": Whatever they're coated with, I don't know, but they sound like nothing I've heard before. No SPC or OCC of different thickness, braids, configuration could compare. Well, I thought, wasted $50 - since it didn't sound right with anything. Forgot about them for a while, until COVID quarantine gave me time to do some serious cable-swapping sessions.
Usually I would use SPC to boost treble, Copper to tame treble, thick multi-core copper to boost presence area. This time it was "let's try wacky contra-intuitive combinations" - improvise. To my surprise, MMCX one found its home with FH7, and 0.78 one - with ASG2. Both were barely usable to me before that. Thin Shozy 1.4 cable for a while was the best match to Blessing2.
So, my point is - Yes, you cannot trust Ali-Express sellers. Buy cables for collection, if you can afford, and maybe you get lucky to eventually find a synergistic one, like I have. One of the best sounding cables that I've tried with Legend X cost $10.
I'm not saying that Penon or better NiceHCK cables don't have potential to sound better due to just better quality built and materials, but I definitely don't have budget to buy dozens of high-end cables the same way - to keep them in my collection, waiting for perfect synergy in the future.
I don't believe that pure silver is much superior to pure OCC. Testiments on EE thread supported my own experience with LX at the time. Pure conductor of similar makeup will sound similar. Conductivity difference between copper and silver doesn't matter for IEMs. Bi-metals - different story because of "skin effect" - frequency-dependent surface conductivity.
I trust my ears. I know for a fact that 2 identical 8 core "SPC" cables may not sound the same.
One from NiceHCK was boosting treble while another was neutral, which means tinned - not silver plated. Same thing with Yi%#$% cable that was insanely bright, while another one (i believe FDBRO) was the same 8 core configuration and more neutral(tinned, not SPC or very thin plating).
I trust your expertise, you've helped me with it more than once, which I appreciate. But the problem is - me with my freaky ears. While objectively I can assess quality by comparing to reference, difference between IEM having "magic" is so subtle, that it comes heavily to personal "preferences" and thus - unpredictable, +-1db here and there - and the magic is gone. It was like that with Orb.
So, before dumping money in the $$$ cable collection, I need to experiment more with cheap ones, and if I get cable that claims GPC and not softening treble, i'll know that. Placebo effect doesn't affect AB comparison. (not with me anyway)
Also, before I spend $800 on the cable, I could spend it to buy Thieaudio Monarch and get better quality gain with stock cable (for which it's tuned BTW). Just an example. Also, that BGVP Zero is warping my brain with that EST treble. If I could find Blessing-type tuning without BA or Piezo... It makes me re-evaluate chi-fi. Maybe no BA TOTL? Rah & Zero redefining audiophile sound for me.
I've learned a lot from that review. Awesome job there!
I'm planning to read more cable reviews. It's fascinating.
There is one thing however, that I found to be more important at this time - find portable DAC with competent EQ. Cable can only get you so far...
