You plan to add support Google Chromecast by a future firmware update?

Dear @VintageFlanker ,
Thanks for your detailed measurements and feedback.
According to our speculation, it may because the 2.1vrms is a little bit higher, which causes the ADC produced a significant distortion. If you reduce it to 1.8vrms, would it be better?
We will do more tests regarding this issue, if it is a bug, we will make some improvement by a future firmware update.
Anyway, really appreciated to your feedback!
It is a quite unique feature of your device and i am sure a relevant selling point. I believe it is in your interest to see what is going on and report back. Thanks :)

I sent the D90SE back, so I still have to get another (transparent) DAC with variable output to test it. No doubt I will try lower output and see if the IMD clipping is gone.
Anyway, really appreciated to your feedback!
You welcome. Many thanks as well for responding!:)

Absolutely @MatrixAudio - you are to be commended for pushing the boundaries, adding the linestage here was very smart. Any chance of making it a unity gain buffer on the next edition?

Do you mean the input gain or attenuation to the line input channel?
Please see the following screenshot:

Am I understand correctly?

@lordearl, why don't you just use S/PDIF to connect your player? The Mini-i 3 outperforms vast majority of CD players (if not any) out there, when it comes to DAC's performance.;)
Oh sorry I mean as a unit for switching between various sources, I was planning to use the mini-i 3 pro as a preamp as well. Eg with a DAP that has no digital signal out or a cd player (point taken coax or optical would be fine).

What about something like the Denon Heos Link2:


Not sure it supports Qobuz but surely the analogue line in is engineered in a more orthodox fashion?

There is new firmware for X-SABRE 3 as well. Build 048 but there is no info about it in @MatrixAudio website. Would be great to get the changelog to know what they are fixing in this new firmware.

Dear Enrico,
The firmware 048 also fixes the start up issue under rare cases, most of the customer would not meet the issue.

Besides from the measurements did anyone compare this DAC to a ADI-2 DAC FS in practice and also listening tests ? They both look like amazing options.

I really like the design and display of the Matrix but all these sophisticated engineering and the functionalities ive read about the ADI impress me aswell.

In my subjective listening tests , i preferred the RME ,maybe because there are a multitude of ways to tweak the sound.

Hey! I was thinking of using this as a dac for the Topping A30 Pro. Will I get the full power output from this? From my understanding, the output impedance is not going to be an issue when using an external amp, and I will achieve complete transparency using this combo?

"I adjusted the volume down 0.5 dB to get 4 volts out"

Do I have to do this? And if so, how?
