Hi! I would like to upgrade my system with external DAC. I know it should has optical input but what will wiim send when using Tidal MQA or Amazon ultra? Will it downgrade to 24/192 in Amazon's case? Will it send only FLAC from MQA in Tidal's case? Should I look for DAC with mqa support? Will it change after MQA implementation in november? Or maybe analog RCA output will be better than optical? What are Your suggestions?
