Today, very happy can finally speak with you, CAYIN has its own ID account on HEAD-FI, we hope that there is a formal and correct way to let everyone know the brand and CAYIN CAYIN products, and strive to provide better service.

Of course, I will still be here. Follow comments or questions to every user of the proposed use of CAYIN products, and I am committed to improvement and directional explore products and maintain communication with you. And mobilize resources to achieve as much as possible. this is one of my main tasks.
 
Today we are in the HEAD-FI product range is still limited, but in my plan, in 2015 we have a new DESK-FI and HEAD-FI products launched, as we prepared to do a 22-year tube amplifier, CD player, etc., we will thoroughly demonstrated the strength of our research and development, quality assurance standards and understanding of sound, and the user is the only thing we focus on strength.
 
I would like to, CAYIN will bring you more, and I look forward to continue to have new friends to join, and then told everyone to learn and to progress.
 
Thanks everyone.

Thanks to you guys too for a very reasonably priced portable amp.
 
Hope you can release a black Cayin 'C5+' with a balanced RSA/Kobiconn connector and longer battery life.
 
It is a sweet little amp, and I'm sure my upgrade recommendation above would also have strong demand.
You could even do a limited test run of 50 on Massdrop etc...

Yes, welcome to Cayin on the forum. It is good to see manufacturers showing an interest in their customer base and participating in this forum, it is most welcome.

Would love to see a C5 for IEMs, without the plastic end cap.

I use it on a daily basis with X5 and 1plus2 => love the synergy!!!

I've had this rather annoying crack for a while now.  I'm sure some others mentioned the same thing earlier in the thread.  Has anyone else had this issue and is it worth trying to do anything about it?
 

 

[clee290]

It has happened to mine as well. I personally won't be doing anything about it as the crack doesn't affect the C5's performance.

 

[amigomatt]

Yeah, I'm thinking the same.  I've treated it well though, so it must really be a weakness on this thing.

Lobh we have see that you have modified the Opamp with ADA4637 yourself can you share with us what the difference are after you have modified? thanks.

Sorry for the troubles guys. it is what we need to improve in our next version of the amplifier. You are correct that the plastic cap does not affect the performance but with crack it does not look nice. If anyone of you want to replace such part please contact our service person by sending emails to sales01@cayin.cn.

It's no problem, it's the inside of the C5 that really matters 

 
And would I have to send in my C5 for you to replace? Or you send the plastic piece to me and I can replace it myself?

Also, I'd just say planar magnetic headphones can be quite demanding on the current stock battery capacity. This amp goes particularly well with my own modded T20RP woodie headphones....especially in the sense that the amp does not make the treble strident/etched. I think the plastic cover needs to go and the volume dial gets protected from accidental hits like Sony/Fostex do with their latest mobile amps.

Sending back the whole unit is too complicated and costy. We can send you the plastic piece and it is not difficult to replace.

Oh great! I think I will be sending you guys an email
