I see a lot of people favoring the Topping DX7/s but nobody talks about the Matrix Mini-i Pro 2 and the Matrix Mini-i Pro 2S.

Just in case people don't know it, it's in the same price range (400-500 us$) but comes with IR remote, bluetooth APTX input, it has balanced XLR outputs, comes with a ESS SABRE Ultra ES9016S (8 channel audiophile version) and OP amp LME49720.

Here's more info:

I can't find any reviews or discussions online, so if it could be reviewed or anyone has had any experience with it, I would really appreciate any comments.

Yeah, I don't really care about the headphone amp functionality.
Nevertheless, I haven't seen any alternative with less than 10 ohm output impedance in this price range (I believe Topping DX7/s are <20 ohms?).

I do have a Sony MDR-MA900 which are 12 ohms. You mean low impedance headphones like this one could could issues?

High output impedance can shift the frequency response curve on headphones / earphones. How much or how badly affected depends on the phones in question.

If you're looking at connectivity with a DAC function, maybe you can take a look at the SMSL DP3. Its wifi and LAN connectivity is hard to beat anywhere. And that's on top of Bluetooth.

Looks cool, but seems more focused on the heaphone amplifier part (which interests me the least) and doesn't have a balanced analog output for speakers.

Ah ...ok. Haven't look at too many with multiple connection options that have balanced output for speakers yet.

If BT 5.0 (fully backward compatible with AptX and AptX HD) is of interest, you could get a BT 5.0 receiver that has Optical and Coaxial outputs for the DAC of your choice though. I use one from this chinese brand called 'Mission' for my DAC. Pretty convenient when its purely for ambient music.
