Yes, the stock balanced short interconnect does not have ground connection. It only have 4 wires, connecting L+, L-, R+, R-, the ground is not connected. I thought we have mentioned this several times in this thread already.

Thanks for this clarification - so I will need to get into the details tomorrow.

Got a M30 audition unit from Andrew today (excellent service as always!!).

Quick listening impression is that it is NOT a step-up sound wise compared to C9 stack. Source pairing in C9 will be the key to get the right synergy with your IEM/headphone, but it is also the fun part.

That thing is massive! Sheesh. I’ve been curious about this tho….look forward to your impressions

If anyone is interested there are 6 of these left in stock as of this posting, they were out of stock each time I checked before now:

Thanks for the update! They were already short on inventory when I tried to order 4. Rats!

Sorry you couldn't make it!

Who'd have thunk the next hardest thing to get after a PS5 is a set of Orbitronic batteries

Oh wow. A Sony DMP-Z1 competitor perhaps.

This thing is huge, but sound wise I don’t think it beats C9 + a decent musical source.

Isn’t there going to be different modules in the future?

I think it will, and Shanling’d better deliver some good ones, otherwise it is hard to keep M30 competitive.

Nice @bluestorm1992 ! What I do like about it the organic sound signature. And how the Nutube implementation sounds different. Of course the inter connectivity with my current desktop set up is excellent. Enjoy!

Uhh, I am experiencing a very disconcerting humming issue in my setup consisting of N6ii, C9 and Beyerdynamic Xelento. For now, let me briefly say just this:

1. How it sounds: Like a mains hum, plus sizzling noise when touching any metal cases or the N6ii screen(!). Important to know: No connection whatsoever of any device to any mains wall wart, all on battery. No computer involved. Sounds a bit like what musicians on stage create by touching cable plugs or sockets.

2. I tested a whole bunch of combinations. Single-ended and balanced from N6ii to C9 with the C9 stock cables. Xelento on single-ended and balanced. Switched N6ii modules. Used some old Sony MP3 Walkman earbuds instead of the Xelento. Tested with my Sennheiser HD 800S instead of the Xelento. Brought my Hugo 2 in, too.

I will report on the findings from all that later. As tempting as it might be to describe things now, and as tempted as you might be to ask for specifics, for the time being I‘d like to just ask one question only:

I checked my cables with a multimeter. There is one puzzling finding for the 4.4 mm stock interconnect cable that came with the C9: Out of the five TRRRS connections from one plug to the other one, the S (sleeve) connection has infinite resistance. @Andykong, please, is this correct? There is no sleeve (=ground) wire in that cable? Everything else is 0 Ohms for identical ones TRRR to TRRR, and any two non-identical connections like e.g. T to R correctly show infinite resistance.

Thanks for helping me to clarify this one thing up front. In case that particular cable of mine is good, I will for sure return with more specifics and questions.

Yes, the stock balanced short interconnect does not have ground connection. It only have 4 wires, connecting L+, L-, R+, R-, the ground is not connected. I thought we have mentioned this several times in this thread already.

Okay, I have posted a detailed description of my electrical noise issues over in the N6ii thread now:

I would be grateful if you folks here would visit the N6ii thread and help me out over there.

Just an effort to get the answers into one place, please! Thanks.

Well, I will try to answer it from a point of view by C9 as an external amplifier. There are only 2 possible scenarios where the C9 would cause noises

1/ Ground loops, it is due to the ground connections between the source into the C9 and the possibilities of the battery modules active ground being burned out or bad. This is just theory as I have not seen it

2/ the source itself is defective, where as it would have noises and HiMD, crackles...etc, which could range from many instances, for example, touching it or sitting next to a phone ....etc

Fortunately, the only thing that complicate the ownership of the C9 is just the charging together with turning on. This can trigger the protective behaviors

So then again, for your scenarios, I suggest that your N6ii is defective. You need to send it into the place you purchased it from

Beside that, I don’t know what else I can think of that can technically explain in details of what you are experiencing. There are a plethoras of possibilities for electrical devices to be defective. Many of them just won’t happen right away, and that some devices can be working and passing Quality Control , then to stop working just a couple weeks or months later. That is why we are having warranty

As a consumers, if you are facing hardship at your dealer regarding warranty or trading for new devices, then consider to stop purchasing from them. It is a common practice that for a good dealer, if someone complain about their N6ii, and demand to trade for another N6ii, the dealer lose nothing, just turn in for Cayin and logged down the trade for warranty. The responsibility of warranty is upon Cayin and not the dealer. So there is no such Bullish as “we can’t replicate XXYY”

Good luck!!

Now, to clarify, I have modified N6ii T01 and I have A02 with C9. I also have all kinds of IC cables. I do not have noises as you mentioned
