OMG Did you just say Tube Dongles?Basically, I completely agree with your opinion. Here are some reports.
The independent decoder has been developed and is currently preparing for mass production. As you can see, there is an R2R with a huge VU table and a bold buffer decoder.
The independent pure Class A headphone amplifier has completed the ID design and is currently in the planning stage. It may be launched by the end of the year.
3. Desktop headphone amplifiers will have K13R2R and K15 to fill the price gap.
USB DONGLE will also have more interesting models, including tubes and R2R.
5. More competitively priced closed headphones and open flat-panel earbuds are both on the way.
6. The IEM market is very troublesome. Nowadays, a large number of new brands have emerged in China. To be honest, due to the existence of solution companies and the popularity of 3D printing and CNC machining technologies, the threshold for doing IEM has become very low. Coupled with the limitations of product technology (space, etc.), I think now IEM is more of a marketing and appearance gimmick.
