Do you know before you open the N6ii Ti package which unique number you are getting?

Follow-up on the ”infamous noise issue“ in my N6ii/C9/Xelento combo:

Reports started here:
… and the last one had been this:

… with lots of posts in between.

I received my iFi Audio 4.4 to 4.4 TRRRS cable, in order to eliminate the stock C9 IC. Dear @Andykong and @Whitigir, guess who would receive the winner‘s prize if there had been a bet on the two possibilities mentioned before?

The really good news is: Absolutely none of the noises described anymore with the iFi 4.4 IC instead of the stock one. So happy! So lucky none of my Cayin gear needs to take a trip to China!

I do thank all of you who contributed help and advice: @Andykong, @Whitigir, @twister6, @Nostoi. Forgive me for inadvertently omitting anyone.

Now it might be a pathologist‘s task to find out why the stock C9 4.4 IC fails. Remember:
(1) I couldn‘t measure any inappropriate D.C. resistance with my multimeter (”digital“, though not a Fluke).
(2) The stock C9 IC has no grounds connection in the TRRRS, while the iFi has.
Two hypothetical possibilities exist:
(a) The stock IC developed some inappropriate very high resistance shortcut inside, causing the noises.
(b) There still might be a strange condition inside my N6ii or C9, which causes noises when there is no grounds (S pole) connection between the two. Introducing a grounds connection might mitigate such condition if it exists at all.
Myself, I tend to assume hypothesis (a). A replacement Cayin 4.4 IC is on the way, which might provide a clue at some point in time.

Now, back to music! And thanks again for all the great help, I appreciate it a lot.

Thank you very much for your update, this is very good news. I am glad that the grounded 4.4mm interconnect has solved the problem for you. But I want to remind you that when you used a grounded interconnect between C9 and your DAP, you need to pay attention to the protection mechanism of C9 protective circuit (HERE).

Just made an enquiry as to my N6ii Ti stock situation and have been advised that although I reserved one, due to a 'misunderstanding', I will now not be getting one. Gutted to say the least. Wasn't expecting that from this well known retailer. I was sitting here patiently waiting. All have now been sold and I believe all 600 units are sold worldwide.

Well most will be buying the next best thing , so wait a month and you can get that.

If you live in the EU or Swiss, you could get one from the German distributor. According to their website, they currently still have the Ti in stock.

exactly what i feared for when i was getting mine. the paranoia was strong, especially here in singapore, there are too many scalpers. one off limited edition stuff often gets snatched by those with too much money to count with too little time. so when i was advised that the units are in, i clocked out early from work just to get it. haha

Thanks for the heads-up! Yes, already before all that, I had never been simultaneously charging and running the C9, and I had never been charging any source when connected to the C9. This includes running the N6ii as a USB-DAC off a computer. I‘m promising to myself to never do this in any future.

The only simultaneous charging and playing sometimes is with the N6ii stand-alone, e.g. during module break-in. For that I would use a ”slow charger“ (like standard Apple) instead of fast charging to keep heat generation lower.

By the way, there is one more step in the pipeline: The German importer asked Cayin Zhuhai Spark for a stock C9 4.4 IC cable to lend me. Just for a check whether it will behave similarly to the failing cable. I will report back then.

You got the Odin and LXSE(2021)?
Can you compare to the output of E02 or other boards?

Sorry, haven't tried E02 or E01 before, so can't comment on it.

Tried to do some comparison between A01, T01, R01, A02 and N8 though. All on 4.4, A02 to C9 AB SS. N8 on SS.

Bass control and quality
A01 << T01 < R01 < N8
Clarity A01 << T01 ~ R01 < A02
Treble R01 is sweeter than T01 (sorry don't know how to use technical terms to describe)

Think R01 and A02 will be the only 2 boards I need. R01 (or N8) for daily use, A02 stack with C9 for home use (well until the Vannuys case arrives)...

Think LX SE is a better choice for me compared to LX OG. I prefer bass with control, and maybe that s why I prefer LX SE with N8 than R01...

Hope this helps....

That's my plan, too - A02 plus C9 for home, R01 elsewhere (plus Lotoo P6K).

Between R01 and A02, which is more resolving - I.e., better detail retrival, better transparency, imaging etc?

I will give it to A02, marginally.

Yeah! T01 is such an excellent module. I think most people are overwhelmed by the technical details on paper and or the hypes. Sometimes they just forgot about the listening and the experiences itself. I majority use A02 to C9, but when I use N6ii alone as a DAP, the T01 has al my votes

I bet u r referring to R01...

Nope! Not there yet lol!!!

For anyone interested, there is a like new N6ii Ti in Musicteck now.
