I don't have this problem after the firmware upgrade, which probably means your unit has a screen mapping problem after the firmware upgrade, possibly caused by a Cache memory problem. Can you perform Erase all date (Factory Reset) under System Setting > System menu? Hopefully, this will clear...

Do you mean your N3Ultra is not responding when you click the Next and Pre button on the main playback screen?

I missed this post until I compiled the impression list on Post#2. I think you have misinterpreted Cayin's position. Are you sure we didn't reach out because the review "is not super positive"? Did we respond to Twister6's review with a big clapping hand post? There aren't a lot of examples...

We have also received one report of a firmware update problem that was very similar to your case, he ran into trouble when he updated from v1.1 to v1.2. We cannot figure out the cause of the problem, these are rare instances that can't be replicated, we can only assume this is an Android system...

We have examined this option previously, the easiest option is to implement this as the form of an Android widget, but we decided not to because this will open up a lot of possibilities that we are not comfortable with under the N3Ultra direction.

I have heard both original Utopia and 2022 Utopia with HA-3A and HA-6A at a retail shop, my friend is a shopkeeper so I went to his shop to sample different headphones when I needed to work with a new amplifier. He simultaneously uses iDAP-6 as the source, I2S or S/PDIF to 2-3 DAC, and connects...

I have updated Post #2 with links to important references, reviews, and user impressions (up to page 50) from this discussion thread. I hope the list will provide help headfiers and new comers to explore the N3Ultra effectively.

Try to find the smallest safety pin, it should work. SIM card tray is getting smaller after the industry moved to nano SIM, as a result, the ejection pin is also getting smaller.

I'll raise their attention to the inadequacy of the current UI design and urge them to improve the readability of the song list. It probably will take a while before we do anything solid but your suggestion is heard. :pray:

The 3D printed prototype will assist us in making an informed decision regarding the external design of the portable amplifier. From here on, we shall carry out further structural optimization to include internal details such as PCB mounts, suspended installation of Nutube, and rails for the...

I promised to come back when we make any progress on the C9ii. 3D printing has become an essential part of our portable product development, it is a lot more efficient than old-school prototyping when we can feed our CAD modeling to the 3D printer directly. These are snapshots from the R&D...

To make it easier for the readers, I have revised my signature, let's hope this thread will pick up more tech. discussion on portable vacuum tube applications. :beerchug:

If you switch off the main power, it certainly won't update the system clock. If you set the Date and Time to Auto-update, the iDAP-8 will catch up with the clock when you power on again. If you have connected to WIFI before, it will automatically connect to WIFI after powering on, if you...

This is a WIP project, we haven't finalized the industrial design so it might look differently by the time we launch it in 2025. It is transportable so we designed it to run on battery or AC power. This will be Cayin's first attempt at an AIO (All-in-One) product and the player section will...

I find it interesting to describe the limitation as a "manufacturer claim". For those who are interested in pairing Susvara with HA-3A, I would like to quote my previous sharing here: One distinctive R&D objective is to develop HA-3A for the best quality within certain limitations. It is not...
