Recently compared a Topping D50III ($250) to a HoloAudio May L2 ($5K). SLIGHT differences, where depending on music played I SLIGHTLY preferred one over the other. DACs linked in Roon, volume matched, both connected to preamp, so could switch source on preamp with click of the remote. Differences in musical recordings and personal tastes are more decisive than objective quality.
And yes, I selected the D50III based on excellent measurements and listening reviews on ASR. The May was chosen based on review by Goldenear who infamously debunked MQA.
