Agree. These orbtronic ones sound calmer to me with better clarity.

Are you kidding me? Now I have to worry about what batteries I use?

You don’t have to, the stock batteries already sound great. It is just for people who would love to maximize their system potentials into the “last drop” of %

No you don’t have to. The stock ones are fine. As Vince said, this is really just the last 1%. I will rec it mostly because of its extra capacity.

Narrator: And yet they all knew that yes... yes indeed @HiFiHawaii808 had to worry, and it would only be a matter of time until he purchased some for himself.

You also have to worry about the room temperature. It will sound best if you listen/test your music in a walk in freezer or place your gear in a regular freezer and gently close the freezer door on your cable. Another worry is ear wax best is to remove the wax in the center of your ear canal and leave the wax coating your ear canal walls. Actually if you can freeze this wax it will allow the treble to travel much easier into your ear drums. Epic conditions.

BTW, anyone interested in getting new batteries should consider this, as has been recommended several times here. I have used them for a couple of days now. Longer battery life and even cleaner sound.

Anyone know where these can be ordered in EU? Shipping batteries from the US doesn't seem possible.

Not that I can find, but if you search for Panasonic 18650 3500mAh you will (most likely) get the same cell as these are again, most likely just the same Panasonic cells with a branding shrink wrap applied.

Thanks, I did indeed find these though no idea about their quality. Not so much interested in alerting tonality, but if they run a little longer than stock Sony ones, then winning.

They look OK, The NCR18650GA part number was a number I kept seeing when searching for these too.

Had a week now with the C9. Really happy with everything. Great buy!

Tube class A is my preference. This thing has oodles of power.

 

[bluestorm1992]

My goodness, the Kennerton Rognir is GOOD with C9.

Yeah, but the Panasonic label has a much richer bass response. Haha.

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, this issue has been clarified and resolved now. Please follow up here:

hi all

need your help here,
I bought a c9 just 3-4 months ago, used it a few times, but now when I press the power button, it stays for a few seconds and shuts down. the green lamps do not even light.
the c9 is connected to the power line, 4 batteries in, and on the battery indicator it is showing 4 orange lights while plugged to electricity however shows no indicator at all when I plug out of electricity.
I tried to charge the batteries with a charger I have, It shows they are full, but once I put insert them into the c9 it shows not signs of battery.
I think I used the c9 about 10 times until this happened. Does anybody know this error?

thanks.

Did you try to turn on the C9 when not plugged into AC?
