I just noticed XINHS 8 core graphene cable is on sale for like $60 which I recall it was much higher, aside from sale of 4 core one. I have a qdc finish of 4 core graphene of XINHS and found it’s a pretty nice treble enhancer.
8 core:

4 core:

I was thinking getting 8 core some time and guess it’s a right time✌️

Note: ordered both 4 core/ 8 core 2pin 4.4mm for a hope to save KZ AST and GS Audio ST10’s rolled off DF neutral target ones.

Curious if anyone finds the 7Hz Timeless shouty in the upper mids due to the sharp cut before the lower treble sets in, or cuz 2k and 3k are roughly the same volume. BGGAR says nothing jumps out but his library contains a lot of older recordings which are relatively further from the mic. Then again, modern recordings tend to have more treble volume too so there's that.

The driver nuclear race has restarted in earnest: CCA C24

As KZ (and sister company CCA) unashamedly declare in this product insert: "One balanced armature is good enough, but 24 is better."

Well, they seem to like to add drivers on both sides and total them, to give a more magnificent number, so it is actually 12 BAs per earpiece. But still, any guinea pig gonna take one for the team?

Whenever KZ/CCA, or eternal rivals TRN try to stuff many drivers inside a shell, it generally doesn't turn out that great. Too many cooks spoil the broth, too many drivers give the engineers a crossover headache?

How many drivers are you planning to fit in?
CCA: YES

8-12 violins in orchrestra form a violin section that can sound beatifully smooth and ethereal with good violinists playing all the same music since the individual resonances of their violins/strings smoothen out. BAs are often complained about for their harsh resonances, and BAs all can be near identical - an ideal match for a BA array.

I wrote about it before, but now KZ AST (the most un-KZ KZ) implemented an BA array really well (with 6 or 7 BAs) for smooth and resolving upper mids. So yes , more BAs can be better!

If anything, AST really lack some treble, so I am looking forward to C24 for more than a month (?) now, while CCA still perfecting them :)

Upper-treble does have a pretty big roll-off. Although that lower-treble might be compensating for that.

Gather around, folks. I have a tale to tell of Japanese Generosity!

As I already posted a while back. I was quite interested in 634EARS SARN II, and had placed an order. The price was about $160, and even though there are numerous single DD iems at that price range, somehow I was feeling the need of a wooden shell IEM. On top of that, I have this knack of trying to find hidden treasures - these are the two reasons why I felt myself drawn towards 634EARS, even though I had an earlier inkling for the JVC woody iems. But anyway, I digress.

So I hit 634EARS up on instagram, and got talking. Let me tell you - it's a one man company, and he is an extremely nice person to deal with, but, he also does not take crap from anyone! (Loved that about him, by the way.) I read the sound signature of SARN II, and found out it has a bright sound with strong low end. Now, while I am fond of strong low end, and I prefer some amount of brightness, too bright iems makes it fatiguing for me, and I was also concerned about the bright Asian tuning. So I discussed all of these with him, and asked if the brightness of SARN II can be mellowed down. He explained that only 8ite-TS have the warm and mellow sound signature, SARN II is not designed like that. He shared with me a histogram chart of Frequency Response of SARN II, and informed that he can tweak its tuning slightly to reduce upper end attacks a bit as per my request. I decided to go with that. Paid the amount, and then sit tight.

About two weeks later, he shared with me two different histogram charts with the said modifications - one had more reduction in the upper frequencies than the others. He suggested the one with less reduction, I took his advice and confirmed it, and sit tight. He shipped my iems a few days later.

Once I got the package, and I opened it, I found all the mundane items - cables, a very nice hardshell box, 3 sets of eartips - 2 normal silicone, 1 whirlwind, C rings for further tuning, etc. The iems were in a different box, and when I opened it, this is what greeted me:

20210907_162818.jpg


Folks, there were not one, but TWO PAIRS OF IEMS!! I was completely overwhelmed and surprised and giddy! He decided to gift another pair of IEM just like that!! I never even asked him! What a man!
And then I noticed the writings on the pouches - the stabilised wood one is what I originally requested, and it has the name SARN II written right there. The other one, however, has the name Special written on it. I recognised the housing from his insta page - it was a Granadillo Wood housing. So then, barely able to contain my excitement, I popped the SARN II in my ear. Suffice to say I was completely blown away, but I will continue with my initial impression of SARN II in a later post. Thereafter I tried on the Special, and was surprised to find it rocking a completely different tuning! It was more bassy, with much more fuller midrange, and slightly smoother upper range. Bass was bumped up in quantity. The tuning was different, but still quite good.

Then, I noticed a black thank you note, which, when turned over, revealed this:

20210908_232718.jpg


Guys...I mean...I can't even...he made this SPECIAL specially for me, trying to match my taste from what little I told him! Later through insta DM he confirmed that he tried to replicate the 8ite-TS sound signature with a PET DD, as that is what I requested at first. I of course could not thank him enough for being so sincere...he is one gem of a person, honestly!

I cannot thank you enough, Masashi Saita. You will have my gratitude forever and always for being so sincere to try to create an entirely new iem for my taste, even though you had no obligation to. Thank you. You have a big heart and I feel so fortunate to have a touch of it in my possession.

Can't speak highly enough of that cable. Also got it on sale and what a steal it is for $60. Oozes quality and sound is great.

Do we have graphs for those with the different nozzles? I am intrigued but I don't want a measly bass iem.

Want to know if it's more Dusk or more Blessing2 in terms of bass.
Only graphs I have seen:
