I have been inactive for almost a month, by that I don’t just disappeared from N5ii thread but literally all interaction on HeadFi forum or Cayin Social Media. I was fully occupied by CanJam New York preparation after Christmas. We managed to dispatch the CanJam New York exhibition package (over 100kg) before we start our Chin New Year break. For those who are familiar with our regular schedule probably aware of our busy exhibition schedule from February to May every year.
Last year I was disappeared until we finished Munich High-end (May 2019), let’s hope we can do better this year. For the record, we'll attend CanJam New York (Feb 2019), CanJam Singapore (March 2019) and Munich High End (May 2019) this year.
Just in case you are not familiar with our practice, New Year break is a big occasion in China, this is the only time of the year that we stop our production line completely, and everyone go back home to reunion with their family. We are talking about more than 3 billion passenger-journeys during this
Chunyun exercise every year, and Wiki describe this as the largest annual human migration in the world”.
Fortunately I am only 2 hours away from my Shenzhen office, so I can sit down and catch up my Forum and Social Media backlog while everyone is travelling. I have covered all other Cayin threads in HeadFi forum already, and the N5ii thread is my last stop before I start my holiday.
By the way, my assistant Silvia has started her Maternity leave and we have a new CayinSupport onboard quietly. He needs some time to pick up the pace of his new role (in additional to his busy workload), so please go easy on him.
Regarding the N5ii and N5iiS firmware, we are still working on the 2 sec delay bug before we start our New Year break. As of the last beta version, we can eliminate the 2 sec delay already, but for unknown reason, the USB Audio was severely affected, we’ll continue the debugging and hopefully once we isolate the USB Audio from the operation delay bug, we can release a new firmware already.
The USB Audio is also an on-going improvement work. We’ll release a new USB Audio driver after the New Year break. This will improve the N5ii/N5iiS at certain Hi-Res frequencies (especially 352.8kHz and 384kHz), and enhanced the data buffer management for USB DAC operation. Unfortunately when we release a new USB Audio driver, it will probably be used with other Cayin products, so we need to conduct a lot of verification test beforehand. Hopefully this will be available sooner after the Chinese New year break.
N5ii was launched back in 30 October 2017, it has way passed our regular product development stage already. We shall continue to support the product and handle the outstanding bugs the best we could, but it is unlikely that we can accommodate new features or refinement based modification will be unlikely. I hope users can understand that Cayin didn’t desert our products but we'll run out of resource if we don't follow priority seriously. Being efficient is the only way to delivery low cost high performance products to the market.
I'll try to read through the discussion in past 4-5 weeks and answer as many questions as possible, but I am doing this without the Engineering or documentation/customer support, I hope I didn't make any silly mistakes in due course. Wish me luck.
