Various functions. resolving, stunning power, iem protection switch (iematch?), xbass/space, thrilling volume control experience (u must try turn, its really smooth and solid at the same time) The only lack is pure-amp function. No analogue signal input. Only accepts digital input.

Warm sound. Powerful. Spacious sound. Good driving power. Good looking. But aluminium body is not safe from scratching. Also, It consumes phone's battery fast. It gets little bit warm during use. The only downside is, that there are a lot of dongle contenders at this price point

Considering resolution, it is on the top among this price range. Clear tr sound. I cannot believe its used price is around 200$. Popping electromagnetic noise problem from nx7 was not fixed at all. Do you want the cheap and resolving portable dac/amp? Do not hesitate. Just but this.

Warm and resolving amp. The grain of the sound becomes thicker, and the gently curved texture is conveyed to me. It made me feel so good, as like bakoon's amps have done. I could feel that this amp is supplying enough and enough driving-power to the receivers, but the maximum volume was bit...

Clear, Powerful but not quiet amp. There is a bit right-left unbalance on low-volume but negligible. Smooth volume control, 3.5 and 4.4(unbal) outputs. Popping noise near surrounding electronics was so annoying. (Maybe poor shielding or circuit's structural problem?) However, considering its...

Imaging - "Perfect." Z1R has perfect sound image performance on the all the way. It is very spacious but moderate, and exceptional. Timbre - "Clear Piano sound - like." It gives very unique timbre. Due to the slightly holographic sound character, it reminds me a single piano placed in the middle...

<Utopia 2020> Imaging - "Good." Perfect sound image on the right, left and in front. For the behind, better than stellia but not than MDR-Z1R. General image was not that 'big' than the other open-back headphones. Slightly exceeds out of the head. Image of...

With high viscosity, its sound is like smooth chocolate. W-shaped tonality, thick midrange, close sound image but still spatial (inside of the head), good sub-bass (below 80Hz) and sparkling high. Custom cable 'Lancelot' made its sound more dry (so that it can be neutral in timbre) and shiny...

It has diverse input and output, but lack of bass-resolution was quite disappointing. Without that, everything was perfect. Good build, full of utility.

I really like its output impedance adjust button. Phantasy II with Hi-Z changed my utopia 2020 into 'extreamly fun' headphone, fully bloating around 60Hz, also making soundstage wider, sound thicker and warmer(even hot). Also in Low-Z, it does not harm the resolution of my cans. This is...

Oh, i used stock cable. I felt it was like an uncomfortable 'step' on the high frequency area. Is custom cable works on that? Can you recommend me a cable?

Imaging - "Lack on behind." Stellia has perfect, and again perfect sound image on the right, left and in front, but not around behind of the head. Image of sub-bass is mainly inside of the head, like iems'. It literally shakes off my skull and brain. (It is due to the good...
