Yes, I've noticed a tiny click, almost like a little static spark, starting a new track. And it seems to come from the left channel. Nothing when the track plays, and not loud enough to cause any concern, but it's there. I have different equipment than you, but it is in the pre-amp mode.I have used P6pro + C9 in Pre-amp mode listening Trailli. I notice that there is always "Click" sound when starting the new track. Does anyone face the same problem with me? Is it normal?

Click could be an indication of a switching of some transistors....so far as statics....isn’t that from the digital interfaces of switching data points ? Firmware could fix that, like inject a 0.5 seconds silence or mute to mitigate thatI have used P6pro + C9 in Pre-amp mode listening Trailli.

What do you think to be the source of that click? The L&P P6Pro or the C9? I suppose - or hope - it is the P6Pro.

I went through all combinations of C9 with N6ii (E02, A02) and Hugo 2 by now, if not in depth for some. Using HD800S (even this one!) and Xelento, the latter being not up to the state of everything else.
What a great world opened up to me! Impressive, both regarding SQ and enjoying my music as well as the sheer number of possibilities.
Really nitpicking: Only technical flaw with the C9 - actually it’s stock case - is that the pre-amp mode indicator light isn‘t visible when the C9 is in its case ... just sayin‘.

I was just able to score a new N6ii + A02 (and A01) new at a fairly good price. Look forward to hearing what all the fuss is about (and also wonder how this pairing competes with the Hugo 2 + C9 combo).There are not many good non-Android options these days. Except for Lotoo, the other one is the Luxury & precision’s P6 Pro. An R2R DAP; extremely good sound but with a snappy UI. Also quite expensive...
I would actually recommend to look into Hiby R8. It is an Android DAP and it offers a true LO. Its UI is also probably the best out there.
Edit: Oh yes of course, N8 too. I was going to recommend N6ii + A02, but it is too dedicated and also it is kind of impossible to buy a A02 ATM.
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.Really nitpicking: Only technical flaw with the C9 - actually it’s stock case - is that the pre-amp mode indicator light isn‘t visible when the C9 is in its case ... just sayin‘.
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.

There is a new C9 review by @Wiljen. 
Looks like C9 is on a review tour now.

Beat me to it. I was just headed this way to add a link. All good - free publicity
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.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.

Line in for the win!

Hard to nitpick the C9, its a win in just about every mode. Not a bad choice in the lot, just some slightly better than others.

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
Does anyone have any thoughts on what sorts of desktop amps the C9 compares to, form-factor and versatility aside, whether SS or Tube?
