Most people don't realize how little of the end-user purchase price reaches the manufacturers. Every €/$ adds up to the final price by a factor of four, and that doesn't even include profit. Therefore, they cut costs wherever possible on all devices.First look at the Fiio K17 just susses me out. At that price point you'd expect Neutrik XLR connectors but instead they are ZWEE.
The DX9 is essentially a D90 Balanced and A90 Discrete plus two extra NFCAs in one box.
The D900 and the A900 are the same size as the DX9 so they will for sure make a DX90 or DX900 that's a little bigger than a DX9. The DX9 isn't especially big either for a piece of gear in the audio world.
The A900 and D900 aren't especially crammed on the inside either:

They could easily half the number of amplifier outputs to save space. The challenge would be to make it look good on the inside so it would be pretty with a glass top.
With XLRs, signal transmission occurs only via the three pins/sockets, so the rest isn't that important, even if the mechanical fit of the housings isn't good. I once measured the inexpensive XLR plugs/sockets, which you can buy for well under €/$1 each, under load, and the contact resistance was perfectly fine.
The DX9 is a bit more complex. Completely separate and very low-noise power supplies for analog and digital, completely separate amplifier circuits, not just NFCA, the AK4118 ensures the best compatibility with other devices, etc.
If Topping had added analog balanced and SE inputs, they could have easily sold five times as many DX9s, or more. But since it was limited, it doesn't matter.
