I’ll call Andrew tomorrow.

You may want to experiment with egg rolling.

Once you match the right egg, the case lets you expand the C9's versatility by matching your egg burn-in style to your music genre. From pg 4 of the case's nonexistent manual:

Sunny side up: Pop
Over-easy: Lounge
Scrambled: Rock/Metal
Soft boiled: Hip Hop
Hard boiled: Rap
Poached: Classical
Omelette: Salsa
Overcooked and tasteless: Auto-tune, Justin Bieber, Current-form of Coldplay

Bargain for what it gives you, actually.

Gotta agree it took awhile to sort all the modes out and really get a solid compare between them. For me, Line-in mode, Tube, AB is my preference. I found in pre-in I seemed to lose a little bit of the dynamics that line in offered, AB gives better bass punch and I'm a tube guy, always have been.

That's why I set a longer reviewer time when compare to other DAP or IEM tour, C9 is versatile and ADDICTIVE, quite often I can listen to C9 for 2 hours before I "wake" up and continue my work.

By the way, did you try any not-so-sensitive IEM with C9?

Great Review.
Guess as soon as I need a portable amp I should get one.

Currently I am still hoping that Cayin releases a R2R + Tube DAP until the pandemic is over

I can't discuss future product, or non-existence of future product, so let's skip that and jump to the second part of your statement. Do you think pandemic is over soon? By end of 2021? or end of 2022? One of the collateral damage of the pandemic is worldwide shortage in electrical and electronic components, This has caused serious stress to our Supply Chain and new product development is suffering.

I did and it did a great job with the Hifiman Re2000 Silver and the Dunu Zen so it just needs the ie-match if using things like Andros that are a bit hyper sensitive.

To be honest, I Don't think the pandemic will be over any time soon.

I don't even expect so see the office again this year or for the gyms to reopen in my country.

Therefore I don't need a DAP any time soon and can play the waiting game.
By the time the daily life is mostly back to a pre pandemic Status, maybe my dream device is released.
And if not there is the Fallback of N6ii +R01 + C9.
However step one of receiving what you want, is to make your need known ;)

Not only supply chain issues with electronics,
But in home construction,automotive and many many more industries...
Agreed, virtually in every corner of life. It goes so far that makes you realizes that the society will not just move on it own. Especially humans, no one will be moving by themselves, unless and otherwise having some clear goals in mind.

In the States, the majority of older and experienced workers have realized that they have burned away their life dedicated to works and labors, and Covid makes them realize that life is more than that. So they left a void to be filled in. The younger generations is about similar that they were either enabled or having the same mind set of working just enough to cover the expenses. So they care less about working and being productive.

There are many places, entities, companies, offering high paying wages to hope to get the economy flowing, the businesses to get up and going, but they just won’t be motivated enough.

So, we have a lot going on than just Covid. I think that we are going to come to the point where when you have money, you may not be able to find the things you want either. .. .. lol

Bit of a Sunday morning ramble, apologizing in advance.

Like the point that COVID influenced many to think more about passions, and what really matters to get the most out of what time they have left. Causing an increase in demand for some product categories. There were no doubt some winners and many losers. I was talking with the owner of a local pizza shop and he proclaimed the best year he has ever had.

Our shared passion for the music and the hardware to get the most out of it, is impacted, the music is safe, artists will always produce even if they live on the street, poor as dirt. The current supply chain issues are temporary.

The US culture is different than anywhere else I have been, not better, Americans tend to prioritize their lives in this order Career, Family, Vacation. Where vacation will often give way if needed.

I do not think that COVID has fundamentally changed the US culture to now prioritize leisure activities above productive careers.

We collectively relearned that words matter.
That almost all politicians for the most part are completely self serving, and have very short term mindsets.

We also relearned how dangerous nationalism and racism are.

As the World continues to change some industries are going to decline, for example every one of the manufacturers specializing in making components of the combustion engine, and the transmission and drive train, thousands of plants and 100s of thousands of jobs will decline. What replaces that capacity, and what new wealth will be created in the process?

Intel in the US is a good example of the problem with short term money grabs that lack future thinking investments.

The US culture is different than anywhere else I have been, not better, Americans tend to prioritize their lives in this order Career, Family, Vacation. Where vacation will always give way if needed. This is very different than many other places where the priorities are often ordered this way, Vacation, Family, Career, where career will always give way if needed.

I do not think that COVID has fundamentally changed the US culture to now prioritize leisure activities above productive careers.

The coming years are going to be interesting to say the least.
Fortunately, real life is far more complicated than these, uhm, views.

It may be easy to punch a hole there with a leather punch. just need to cut a block of hardwood to the C9 size to act as the anvil, and measure and mark the outside of the case.

So far I have not even tested that pre amp mode.
So many combinations testing all takes a real long time and a lot of listening. Different modes for the DAP many combinations on the C9 not to mention different drivers different DAPs. Fun and exhausting.

I found a couple combinations I like a lot, lazy or just want to listen and enjoy music is slowing this discovery process down.
Took a close look at the case and the Pre indicator light is almost lined up with the start of the vent slots on the side. It feels like the metal strip is inside where that hole would be needed. It is not going to be as easy as I thought to simply punch a hole.

Best to leave it be, likely not going to look very good as the hole would overlap the existing gap in the case. A leather punch is likely not going to cut through that metal, so a drill or something would also have to be used.

Yeah, and besides that, the light is so tiny it's almost undetectable anyway.

Howdy all. Soon to be new C9 owner. Question...I have previously used a PWAudio 3.5+4.4 to 4.4 pigtail with Sony WM1A to Woo Audio WA11. If I recall correctly, the pigtail was highly recommended to prevent causing damage to the WA11 because of Sony's grounding or lack there of the 4.4 output. Is there ANY reason to use or not to use the pigtail with the Sony to the C9?

Same question but with the C9 and a Hiby R8 using 3.5+4.4 out to 4.4 in. Will it help, do nothing or cause a big explosion?

Thanks for any help.

I'm using a WM1Z without a pigtail, using the Pre mode, with no problems. With a short interconnect, C9 will work with grounded or ungrounded, as I recall AndyKong stating in a previous post.
