They are calling their latest gen modules "SDA3", and the Pasithea uses 8 of them. Morpheus has the SDA2 and uses 4. So that's interesting in and of itself.
But also interesting is the idea that the Morpheus may be able to upgrade to SDA3 modules. I know Cees usually designs them to be modular, and I believe Morpheus is no different. No idea on whether he really intends to make this happen, let alone time frame, cost, etc, but it's potentially a great way to boost Morpheus without spending big money on a whole new DAC.
