Pros & Cons

Update Pros and Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

The price tag is more than justified if you're a tidal subscriber looking for compact dac that offers portability and mqa rendering.

Customers and critics rave about this dac headphone amp. The dac itself is powered by the ess es9281pro chipset. The onyx combines a high quality dac with the venerated thx aaa headphone amplifier.

Onyx + mqa is a magical little beast that's letting me'rediscover' stuff i've been bored with for ages. I feel like my headphones are up two notches.

The onyx no problems with disconnecting. For what it is intended for, it does very well, and i was shockingly surprised. I suspect most of the reviews on here that describe a lackluster experience with this device simply failed to take these steps.

Cons

Onyx does not correctly identify the incoming audio stream. I'm guessing this is because the onyx is decoding the audio at a slower sampling rate than it should be using. Seams like there are glitches or communication issues that are very annoying.

Quality

This is solidly built and i hope it will last for years to come with great sound.

Given the legendary thx name, i had high hopes for this ultra-portable dac/amp, as the audio circuits built into my phones and ... Read More

Price

So when it went on sale for $50 off msrp, i decided to make the leap.

Tested with ultimate ears live csx, for context this a $2,400 iem.

But if i'm going to spend $200, i'm expecting more than just an audio boost 10-15db and audio clarity.

Competitiveness

M9/thx onyx performs similarly as the two forementioned conditions.

There's a lot of great marketing speak on the product page, but this isn't going to compete against a dedicated amp/dac.

Other dacs i've tried at similar prices bring more color to the audio that would be better for things like listening to music.

For some who may be interested i compared this to hidizs s9 pro.
