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

Product with Lithium battery installed will go through HK, DHL China won't take these order directly.

I did mentioned earlier that our first batch of C9 were hold up in HK for about a week. They don't even log the item into the system during that period, untrackable like a black hole during that time.

DJI manage to ship with batteries directly from China mainland with DHL. Maybe they have special arrangement as they are big company. If you are interested I can forward you the tracking for this battery case . The box had a Sticker on it saying cargo hold only and DHL did open and reseal the outer box to have a look....they didn’t open the product box. It would be better if you could avoid the whole HK warehouse thing.

Just received my C9 today. Need a bit burn in and audition to share in details but first impression is so amazing. Tube Class A is my favorite so far and I will spend some time on pairing it with my sources, IEMs and headphone for more sharing.
Ooohhh!!! So nice !! I am waiting for it here and will let my ears be the judge. I have no doubt using LPGT Ti, and you would prefer Tube and class A

My apologies @Andykong , I looked into the internal pictures of C9 again and indeed you are right, Cayin made the C9 as small as possible, so fitting the additional outlet to allow direct AC and LPSU is not feasible, and not good looking

I gotta admit that one of the first reason why I bought C9 is due to the small footprint as well

Hope it works well with your HD800S. :)

Then your IC will also be very important :)

Thanks for the early impressions. Maybe BX2 has a more of amplifications stages, but as Andy said, it may not have enough swing voltage/slew rate coming off the batteries ? So , C9 is a good choice here, low gain and 50% is enough.

Another thing to keep in mind, my ATH-R70x is 3.5mm terminated, not balanced. So, I was running C9 in low gain with a volume set to 50% from SE output. If I would to run it off the BAL output, volume would have been much lower since:

To quantify your explanation, when you switch from single-ended low gain to balanced high gain, you gained roughly 12dB headroom, that's quite an substantial improvement in driving and handling capability.

Holy Cow!!! He arrived !!!!

Here is how I stacked him up and I chose Max as my line out over other players after the auditioning

And a Pelican Case to carry this stack with me anywhere I would love to.

The stack still allows removable battery tray
The stack allows Max to be slipped out of his Case
The stack allows removable solution for each piece if needed
The Stack allows laying Max face down without worry as there is a case

The Stack solution can be purchased by Walgreen or DrugMart in the Picture hanging isle :D

You will notice that I arranged my Pelican Case carefully to keep both the player and stack in place including the Interconnect. The explanation is that this is my “EndGame” IC, the Furutech doesn’t like to be inserted and removed too many times. So I carefully Matched up the other DAPS that I have on hands and chose the best to let it stays this way. They are officially “Married”

What made this stack stands out with Max as a source ? Well, Soundstage, clarity and airiness, details, imaging are much better than other DAPs!!!

You may ask why am I using stock cables outlet on Hd800s, well because my main is the HD800S-Anniversary and so she stays home with the best cables I have had :wink:

Now the most important question: How does it sound with your HD800s!

Plenty good Hah!!! I was worrying for nothing. The C9 ain’t going anywhere
Great that it works for you! Congrats! With burn-in the C9 should get even better.

For those that received theirs, when you remove the c9 from the box, underneath there is a square cutout , not very deep, as if a card or something should be there, but there is nothing in mine. Did anyone else notice this?
