Ya I didn't appreciate it until I tried other EL84 and was surprised that it changed the sounds as much as swapping the 12au7. Its really a damn transparent tube amp!

Hi everyone, I was about to pull the trigger on this amp, but now that I see even some comments from Andy I am not confident anymore

Can anyone please tell is this amp good to buy without having to deal with hiss issues or is Cayin in the process to design a new updated one

does everyone have hiss issues, as having to deal with hiss issues is a huge no no

I’m in the middle of debugging multiple issues with my HA-1A MK2, which I bought from a fellow head-fier. Although it does sound great - there are too many issues to be able to fully enjoy mine. My unit suffers from transformer hum (possibly caused by rough handling during shipment), a very noticable background hiss (although less present on lower impedance headphones) and the volume/source selection section getting completely bypassed when I connect a line source to the cd-input (as in, both knobs don’t function anymore). Interstingly, the background hiss is gone too in that case, which makes me suspect there is something wrong in the volume control or source select circuitry..

All in all it’s been a big headache for me. I still hope to resolve the issues with Cayin, but can’t recommend this amp to anyone at the moment. I will update here when I find out more.

I have to add that mine is one of the earlier revisions, so some of these issues may be resolved with later revisions.

The best pairing I've had that eliminated the hum/hiss is with Holo Cyan R2R dac. Absolutely the blackest background!

We are not in the process to develop an updated version of HA-1Amk2, I have proposed a minor upgrade version with 4 pin balanced output but that has been rejected.

What headphones will be used or plan to use with the HA-1Amk2?

By the way, I have avoided to comment on subjective issues as much as possible, but that doesn't mean I am not in a conflict of interest position. So please be reminded that I am a sales rep. of Cayin , for that reason, it's natural to take my advice with a grain of salt.

I can confirmed that braaam has discussed with me on the transformer hum and background noise issue. He has also informed about the volume/source selection issue but unfortunately that was after we have break for Chinese New Year (11-25 Feb 2018), so the detail has not been reviewed by our Engineer yet, prima facie evidence suggested that the amplifier is damaged because this is the abnormal and first time ever we have "the volume/source selection section getting completely bypassed when he connect a line source to the cd-input".

For the record, braaam is located in Europe and he bought the 120V version HA-1Amk2 second handed from US.

Thanks Andy, that is exactly why I wanted to know if its a single unit incident about the hiss. We have a cayin dealer and I am now contemplating which cayin dac and amp I will buy. I know having you on board is always a great asset. Soon I will share my experience with one of your gears, so its decision time
