Topping DX7 Pro vs Monolith 124459

I’m considering a DAC/AMP combo unit & looking for any comparison advice. Topping DX7 Pro vs Monolith 124459

I’m also considering a DAC / AMP stack, with the TOPPING L30 + E30 stack vs the JDS EL DAC II + EL AMP II Stack.but figure it’s more fair to compare stack to stack and combo to combo.
