Dear Vamp898 from distant Japan - you described this issue very well. Unfortunately, from what I can see, there are only two of us who have a similar opinion on this thread about the necessity and sense of using the latest versions of operating systems.

I recommend a completely new and interesting review of Astell & Kern Kann Ultra DAP on a Japanese blog - use the translator https://sandalaudio.blogspot.com/2024/04/astell-kern-kann-ultra-dap.html and review a balanced class-A headphone amplifier Astell & Kern PA10 - a good and proven pair for...

IFI ZEN DAC-1 - the lack of balance between channels can be forgiven This is the first version, some childhood defects may occur IFI ZEN DAC-2 - I replaced my unit twice without success I checked in the store at exhibitions - this applies to each unit/potentiometer to a greater or lesser extent...

I'll ask Does this next ZEN DAC ...3 series remain faithful :rolling_eyes: tradition that music on ZEN must be listened to after 10 or 11 o'clock on the potentiometer, otherwise channel imbalance causes irritation. I hope this is not the case, because the knob in the new one is different and...

Your statement is right on point.

But I know why new applications are not compatible with the old version of Android, and why, for example, the first version of the flagship FIIO M15 (a great player) is dying, on which I will no longer install the newer version of Tidal. In the case of DAPs and smartphones, manufacturers have...

I don't even dream about Android 15 in FIIO because it's still to come. There are a lot of links about Android 14, including those you wrote yourself.(This is an interesting topic) I will patiently wait for the stable use of at least this version of Android 12 in FIIO, in how many device...

This new FIIO K19 "balanced" amplifier is interesting, but is it fully balanced?: - Balanced XLR4 headphone output - has - 4.4mm balanced headphone output - has - Balanced output 2x XLR - LineOut - has But where is the balanced 2xXLR input - Line IN?

How many years have we been hearing about the upcoming Android update in FIIO products ?:sleeping: For FIIO the world has stopped at Android 10 at new products too :rolling_eyes: Knock knock - who's there? - so Android 15 I'm coming in August 2024 but not for FIIO. :scream:

When I was young, it was hard to come back to reality after a long weekend. But it took over 3 months for Tullamore to recover after the trip and without any visible improvement - it must have been a rough event :beerchug: Still no material from Sennheiser's headquarters.:slight_frown:

"When the tubes are close to antennas or wireless devices, users may hear a noise like a "sizzling" sound through the headphones, which severely affects the audio experience, turning the carefully designed tube sound into a potential flaw. These issues were experienced in our previous models...

Unfortunately, the Chord Mojo 2 only has 2x 3.5mm headphone outputs for two-person simultaneous listening or headphone comparisons. Mojo 2 - https://headphones.com/blogs/reviews/chord-mojo-2-review-measurements A common misconception is that Chord DACs have no output stage, but this is not...

For a week I have been delving into the topic of tubes in portable devices on several threads. DAP with tubes is a whole long path of problems and mutually exclusive adversities: -Screen right above the tubes - potential interference -The tubes get warm - this may affect the durability of the...

I have had A&K Kann Ultra since its release on November 11, 2023 and on both firmware versions I had no problem with WiFi 2.4GHZ - 72Mbps, 5GHz-150Mbps (I can't get more, it's because of my not the newest AP) - measurement about 5-10m from the router. I know 2 people who also have Ultra and...

I noticed that in Kann Ultra "Screen Timeout" does not work on the Apple Music application ver 4.5.0 beta - do you also have this problem? Using: Tidal, Spotify or Apple Classical - it works correctly and turns off screen after a set time, e.g. 30s
