This is what my Stellia looks like now. At the beginning, when the discoloration began, a black edge formed on the headband in particular, compared to the original color, which looked terrible. Over time, the transition became more even and therefore more bearable. My initial thought was that it...

Well, what do you call a real defect? Manufacturers and customers don't always agree on this. I can only report what I see and can't explain what happened. I can only make assumptions and the most likely one for me is that sweat penetrated the leather and discolored it, perhaps the leather...

I have had Focal Stellia for a few years now and have had two different experiences. Firstly the workmanship, it is good but not outstanding. Then my main problem, for some reason the temples and ear pads discolored after a short time, they practically turned black where they rested on the head...

I basically like what Etsy has to offer here, one or two of the AK models are just unfortunately not the 3000t. The fact that the screen is protected by a flap is what makes the cases so interesting, the connections only have to remain accessible when you open it so that you don't have to...

I only know the cases in a different color, black and dove, which have already been shown here, but apart from the color and the stand they contain, the rest is identical. Other manufacturers only have a case that completely encloses the device and from which you have to take it out to use it.

In addition, you can hardly use the device without a case. It looks beautiful, but it is completely unwieldy.:smile_phones:

In my experience so far, and without being able to prove it scientifically, the hybrid mode consumes the most energy, as both amplifier circuits are active here. The pure tube mode seems to consume a little less energy, and the OP mode consumes the least energy, which is not surprising.

Now the second attempt with an AK 3000t and this confirms the behavior of the battery. Firstly, in my opinion it is undersized for the power consumption of a mobile device equipped with tubes, a more powerful model should have been chosen. Up to 30% per hour can be used here if you select the...

With the internal SDXC card slot of the M3 MacBookPro. First I formatted the SD card with the disk utility SD EX Fat and then copied my music data - it worked perfectly. The second option is the Android File Transfer, which also works with that. When you connect the AK to the computer, it starts...

That is actually my main criticism, the battery consumption and probably its capacity. A more powerful unit and improved energy management would certainly have been desirable here. Especially considering that this AK has tubes that tend to consume more energy than conventional pure transistor...

If possible, reset the device to factory settings?

As I mentioned above, these are basically devices that are designed for mobile use and whose effectiveness is limited here. However, there are certainly over-ear headphones that can also be used well with such devices; I already mentioned the Focal Stellia as an example. Basically, I therefore...

I use or use a FIIO In-EAR FA19, a Focal Stellia and a T+A P-SE for the AK 3000t. The first two were a good fit for the AK, both are easy to use and make good use of the quality of the 3000t, the P-SE works too, but here I have the impression that it seems a bit tired, for comparison I have a...

Nice accessories, but apparently not available in Germany. Astell & Kern lists two official dealers, neither of which has this accessory, which is a shame and somehow incomprehensible.

I can't think of much to do, except maybe try a different memory card.

Contact problems manifest themselves in the form of disturbances such as cracking, sound dropouts, rustling, etc. that occur when the jack moves in the socket. Normally, there should be hardly any play between the socket and the plug so that it sits as tightly as possible without being able to...

For my ears, the AK 3000T opened up the room more in depth and width the more tubes were involved. The sound benefited for my ears especially when acoustic instruments were used. For other genres like indie, I mostly used the hybrid mode, but rarely the OP mode because I had the impression that...

The battery protection mode is intended for stationary operation when the AK is constantly connected to the power grid, so that the battery is not charged all the time and at the same time it is protected by not charging it completely. You can switch this mode off and the battery will be charged...

When I read the technical data in the manual and look at the noise floor of 120db or higher, you should be able to hear next to nothing in normal operation, at least if you don't use overly sensitive in-ears. I also assume that you don't do any sport with the devices, or even go for a walk...

Do you have a guarantee? Could you perhaps exchange the device?

Have you tried other headphones? I couldn't notice anything in this regard, for example with a Fiio FA19, and I honestly can't imagine that this is normal behavior.

So I can only report from my experience here, a "simple" Apple charging/data cable didn't work with the SP 3000t on either the Mac or my Anker multi-charger, the device showed no reaction. I can only assume that it doesn't meet certain USB3 specifications, which some devices tolerate but the AK...

https://www.amazon.de/dp/B07X45Z97T?ref=ppx_yo2ov_dt_b_fed_asin_title I use this Anker. But I don't think you need to worry too much about it, all modern devices should work here.

Yes, I also thought that it would work with cheap cables that I use to charge my iOS devices and transfer data, but unfortunately it didn't work. My FiiO M11 Plus isn't picky either, but unfortunately neither charging nor data transfer worked with AK. Other cables will certainly work, but they...

My experience is that modern multi-devices are not that different. When connected to a PC/Mac, it usually takes a little longer.
