Every type of music I listen to with this device reveals details and depths I had never heard before. The Cayin N8ii has completely changed my music listening experience and habits.
Line Out Mode
The Line Out mode is typically used to connect to an amplifier. However, when the LO Gain is set to Low, it comfortably powers the 600 Ohm AKG K240 headphones. In this mode, the sound quality is exceptional, with clear and distinct details across all music genres. However, the dynamic range might be slightly reduced. Therefore, I also tested the same headphones in SE mode, which offered a different experience.
600 Ohm Response
The tube amplifier really shines when it has a high gain and a volume selection of 65/100. When it comes to “Roadhouse Blues,” the Cayin N8ii conveys every single aspect with an extraordinary level of detail. It is a one-of-a-kind listening experience because to the 3D imaging quality of the harmonica and the location of Morrison’s voice towards the background.

Comparison: Cayin N8ii vs. Fiio M17
While the Fiio M17 isn’t fully considered a portable music player, I wanted to evaluate it since it was on hand for review. The M17 requires its over-ear headphone mode to be enabled to produce enough power for 600 Ohm headphones. This mode is above the H gain setting, and at 90/120 volume, it delivers a full playback. However, in symphonic metal with massive playback, it achieves only slightly above average results at 80/120 volume and an ultra high gain equivalent setting. The crucial factor is not just the sound’s volume but also how encompassing the resistance’s drivers are able to make it.
When it comes to metal music, the situation doesn’t change much even when softened to rock. Especially the tonal shift in the bass guitar and slight nasal vocals mudding up during the song’s attack are disappointing. Meanwhile, the Cayin N8ii provides full playback at 50/100 volume in H gain, Class AB, and normal P settings with 600 Ohm headphones, achieving a level the M17 cannot. At least for smooth jazz, the N8ii serves well in monitoring, but to ensure fairness, let’s switch genres.
Starting with symphonic metal, the Cayin N8ii offers a surrounding musicality in all genres. The monitoring capability in smooth jazz doesn’t apply to subsequent genres, but the experiences so far in this power test already tell the whole story.
