Any holes in my streaming rig?

Though I'm relatively new to streaming, what I've put together in the last six months is very enjoyable. I'm just wondering if there's something obvious that I'm missing.

I started off with a Cambridge Audio MXN10, and it was better than I expected. But... I soon added a LAiV Harmony DAC and used the Cambridge Audio as a streamer. This was a major improvement. Then I bought the LAiV Audio micro DDC for even better performance. (Most recently augmented with the LHY LPS25VA linear power supply.)

Realizing that the streaming mechanism built into the MXN10 may not be the best, I replaced it with a PS Audio AirLens. This was another significant step up. All I stream is Qobuz, via Qobuz Connect.

I have a mesh network for Wi-Fi. A Furutech Ethernet cable is plugged into the nearest mesh pod. That cable leads to the AirLens. From the AirLens, I have a Furutech I2S cable to the Micro DDC. From the Micro DDC to the Harmony DAC is a DH Labs Silver Sonic I2S cable.

If you think there is something that I've overlooked, or any suggestions/advice you have, please let me know.
Thank you.
