I'm not sure what you mean by wanting to bring it up to date. I had the 372, and later on the 375, and there were no upgrades. The 375 did offer expansion modules for phono and dac, or is that what you mean?
The dac was nothing special, you'd be better off buying a separate one like the Schiit Audio Modi 3, and at $99 it's much cheaper than what the module would have cost.
