We are talking about the potential of the 218 as a (much!) cheaper alternative MQA-enabled Sooloos/Roon end-point for use with DSPxx00DSP speakers.

You would not want to use one with an 818v3 unless you also had an 818v6/8 as discussed here.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
