Just received the first piece of Munich show promotion artwork when the Zhuhai team resume office after the Labour Day break. We have shipped the sample to our Germany dealer, and Cayin will send a small team of engineers and sales staff to manage our booth in Munich High End, we are only days...

May I suggest moving the R2R discussion away from RU7 thread? RU7 is not a R2R DAC and we have our share of confusion in the past, certainly not a good ideas to include more R2R discussion or debate in the thread, and attracting more users looking for R2R product to RU7 through searching...

Yes, the default setting of both EQ and PEQ are changed to local storage in v1.1 firmware.

If you want to erase the music database, you can insert a TF card with no music files on it and perform a music scan, this will create a null music library to replace your previous music library. I haven't tried this with N3Ultra but that's how it work with other Cayin DAP.

The Album art non-display problem is consistent across all user interfaces? Can the album art be displayed during normal playback? Can you upload the albums that can't be displayed properly and let me download and test them in my N3Ultra? I don't need the full album, only two songs per album...

The firmware v1.1 is unlikely the root of your problem because other users are not having the same problem after they upgraded their firmware, maybe the firmware update is not completed properly, or maybe there is a software glitch at the end of the firmware upgrade. Please reinstall the...

I have added Album Art display priority to the FAQ of N3Ultra (Post #2), this will explain the options that enable the N3Ultra to recognize your album art and the options that are available to you in the case of embedded album art is not recognized, The complete album art display priority are...

If the dealer is helping you to cross-examine your HA-300, I couldn't offer any solid advice beyond what they have been doing. Your dealer is always your best bet for repair and warranty service because they can examine the amplifier in person. If you want to seek a second opinion from the...

...before you proceed to the next step. Select "System Settings" on the main menu, at the Setting menu page select “System” and then select "FOTA* Updates” to enter the firmware update interface; Select “Local updates” in the System Update screen. Proceed to the root directory of your TF card...

( N3Ultra is, by circuit design, equivalent to a hybrid Tube pre and solid state output stage amplifier for speaker applications, it will vastly different from output transformer coupled single-end triode amplifier if that was your baseline of tube amplifier, even push pull pentode tube...

It only happens with Tidal MQA? Officially, N3Iltra is not certified for MQA, we didn't listed MQA in our supported format. It might or might not work with certain MQA tracks, depends on how Tidal is handling the track under the MAX programme.

It sounds like your iPhone considered the N3Ultra as a peripheral that draws a lot of power and starts to behave "incorporating". :sweat_smile: Check the Default USB configuration setting, you should set the N3Ultra to Audio in (no USB power) so that your N3Ultra won't draw any power from the...

I received a PM asking if there is any mobile phone screen protector is closed enough to use it with N30LE, so I asked for the screen protector CAD file and retrieved the dimensions page for your reference.

I have included this photo in the opening post to compare the N3Pro and N3Ultra side by side:

Please check out the Soul 170i integrated amplifier review I quoted in the opening post. you'll notice that the KT170 has a very attractive sound signature. It will benefit a large variety of headphones, including the more sensitive dynamics headphones. We are not necessarily aiming at the...

I can't tell you the numbers directly, for obvious reasons. As a consultant, I advised Cayin to position the Soul 170HA to avoid direct competition with HA-300MK2, it's not a good practice to introduce internal competition. Since you are attending the Munich High End, you probably will be the...

They are not interchangeable. You can make an amplifier to work with several, but not the complete KT family. In addition, if you have an amplifier that can take KT88 and KT150, most likely it will starve the KT150 to keep the KT88 operating safely, so performance and optimization are not...

There aren't any rules or patents to stop other tube manufacturers from producing something that can substitute the KT170 in tube rolling, but it will only happen when there is a reasonable demand to attract new players into the niche market. The KT170 tube and amplifiers are pricy, hence...

Cayin Soul 170HA is around the corner, I promise this is something that will you'll WOW when you see this in person. :wink:

That was in the N30LE thread (HERE). I did consider quoting you when I started this thread, so I tracked down your request, and my initial writing was "but he doesn't know we have a prototype that we keep away from his radar" :sweat_smile:

Cayin will debut a new Headphone/Speaker Amplifier at Munich High End 2024. The Soul 170HA, as the name implies, is part of our Soul amplifier series, and it will use the KT170 vacuum tube as the power output tube. While Headfiers probably are unfamiliar with the Tungsol KT170 vacuum tube, it...
