If you are using the Michi X3 dacs and a digital connection I would not see the benefit of changing streamers unless you don’t want to use bluos. If you want better SQ try upgrading your digital cable or your power cord for the Node.
This is from a review:
The headline features are a digital module powered by AKM’s AK4495SEQ DAC chip. There’s a good choice of inputs with a USB (type B) and a trio of optical and coax available. The USB will accept PCM signals up to 24-bit/384kHz and DSD128. The other digital inputs are all specified up to 24-bit/192kHz, which should be more than enough for most people.
