Has anyone compared a Douk DDC to the MATRIX Audio X-SPDIF 2?


The MATRIX Audio X-SPDIF 2 converter seems to be fairly popular on here. I'm looking for a USB to I2S converter. I found a new MATRIX Audio X-SPDIF 2 selling for around $440 recently. However, after reading this review, I'm not sure I want to keep it. https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-matrix-audio-x...The reviewer concludes:

I want the I2S output. So that got me thinking that maybe I should try the low end ($56) Douk Audio Mini XMOS XU208 USB to Coaxial /Optical /12S Converter Digital Interface DSD256 (https://doukaudio.com/products/mini-xmos-xu208-usb-to-coaxial-optical-12s-converter-digital-interfac...)
Has anyone compared these units?

I'll answer my own question. I was able to do an informal comparison and there is no comparison. I could not even listen to the Douk Audio Mini XMOS XU208 for a short period of time. Very irritating sound compared to the MATRIX Audio X-SPDIF 2.
I've been using the Douk Audio U2 Pro model for the past few weeks, to connect my OpticalRendu to my Chord Qutest by its optical input instead of USB.  It's provided a fantastic improvement and would have been well worth it at 10X its actual price of $56.  I haven't compared it to the Matrix, which you seem to like a lot.
If the I2S on a Denafrips DDC can work with your DAC consider them. Really liked the one I had for 192 and below rates better than my other converters, only sold it because I plan to buy Chord for 768 rates
