The streamer is as important as any other component and should be carefully chosen and in general of the similar or greater value than the other components… preamp, amp, DAC.
MQA… not really important. Ok, Qobuz is the best sounding streaming service… they don’t use MQA. If for some reason you are adamant about using Tidal, then your Streamer / DAC needs to unfold MQA. MQA can sound good… don’t listen to the haters… but the technology came too late… it was intended to save band width… well guess what… bandwidth is no longer an issue unless you have a 2400 baud modem.
You need the best possible streamer possible. The sound quality of mine equals my great analog/ vinyl end.
