Your Aune Amplifier has a regular Line Out, does it not? This would be the only way to connect 4 units to the DAC via a secondary (pro audio style) multi-headphone amp land not drop the impedance to a point via a switch at which it would color the sound...although if you're only using one at a time it's probably ok from the Aune's headphone output to a switch. This device will PROBABLY do what you want, but I can't guarantee it's colorless: https://www.walmart.com/ip/Cubilux-Bidirectional-3-5mm-Audio-Switcher-1-in-4-Out-4-in-1-Out-Stereo-1-8-Aux-Selector-Box-Speaker-Headphones-Earphones-Switch-Laptop-Computer-Smar/17774468899?wmlspartner=imp_101044&selectedSellerId=102928584&clickid=U4C17%3A3WTxyZWf2THOwjURsiUkuWPtzpWwlWxw0&irgwc=1&afsrc=1&sourceid=imp_U4C17%3A3WTxyZWf2THOwjURsiUkuWPtzpWwlWxw0&veh=aff&affiliates_ad_id=565706&campaign_id=9383&sharedid= I have one from Cubilux that is measurably colorless for RCA use. This probably works the same way, but I'm not sure how much output voltage it will handle. I'm guessing 2.5 volts but I don't know.
