Cayin C9: Dual Nutube, Fully Balanced Class A/AB Portable HeadAmp

[bluestorm1992]

I really couldn’t go back to the original DAP alone after hearing it paired with C9. I feel like C9 is digging out the full potential of the DAP. N6ii + E02 sounds so mediocre compared to N6ii + E02 + C9, and this is with IEM (UM MEST/U18t).

How am I supposed to do any travel in the future with my DAP alone. May need to carry C9 with me always.

It will be very hard to carry the C9 portably as there are a couple issues.

1/ Dissipating heats. If you are in SS and AB, then it is acceptable, but if you put it in the backpack, it would heat up very fast as well. Now, if you are using Tube and class A, even just leaving it on the table, you can’t even touch it without tolerating the heat and clinching teeth’s

2/ the interconnect or plugs Protruding outward. This can be fixed if you go with “L” connectors all around.

Unless you are willing to look into or customize a case that can host both the C9, the sources, with Active cooling fans that run on battery by itself, and an opening to access and browse the source....at this level of complications....

Great points! Then I think it is not a good idea to use it on-the-go. Probably just put it in a case and take it out after arriving in hotel rooms.

This is the case I'm getting for utopia + DX300 + C9....

Definitely not for listening on the go...

I can't decide whether I should also get a focal headphone stand and also arrange for space within the foam for that...

Size indication from a random youtube video:

Apparently none available in UK until March earliest. C9 as rare as PS5 it seems.

The first batch was very little in number, I assume after Chinese New Year, the productions return and you will start seeing more being made

That's what I heard, too. I'm on the pre-order list and eagerly awaiting March (and hoping it won't be later).

Consider ordering from Musicteck and ship it to EU? A lot of people have done that before.

I ordered from Musicteck before - Andrew is excellent to deal with and the price was good, but I got hit with a hefty customs tax fee in Austria. Other Euro members might have better luck, though, depending on their country.

For 18650 purposes. I recommend this charger . It allows 4 batteries, and has the ability to charge many others, but most importantly is to “Match the Internal resistances” of your batteries. I may have a habit of matching stuff from my own DIY building and even tubes amp....so I always jump in for “matching stats”. This feature is awesome and easy to use

I am using 4 matching of 22mOhms Internal resistances . These will change as the batteries aged down, but at least they should be matched and staying in the range lol

Also, don’t forget to grab your set of batteries. With this one, you will hear improvements in staging, bass, body, textures.

Since I have discovered the batteries and the chemicals that made it will also effect the sound quality. I am grabbing another kind of batteries to check out. Will report soon

Please keep us up to date with your findings re- batteries. Thanks!

Another recommend for Andrew at @MusicTeck from me too. Just ordered a Cayin 6ii plus all boards and the new UM 3DT IEMs from him. He’s literally the best I’ve encountered in the industry!
