I mean for kinda close to the price of the arc mk2, you could honestly get something like an asgard 3 with an audio interface like a focusrite scarlett solo (and an adapter like an antlion xlr adapter), and while this would be more around the 300 range, it would give you a higher quality amp that is more suited for driving the 880 and also a higher quality mic input with room to expand in the future.
You could keep the arc and grab an amp like the liquid spark which would be a better match for the 880 but at that point you wouldn’t really be getting good value for money imo since you would only be using the arc as a dac and mic input (and at that point if you wanted to stay around the 200 range you might as well just plug the mic into your motherboard and grab a dac like the earmen donald or topping e30 instead of an arc as a dac only)
