I am pondering whether to have a go at MQA and how to set up etc?
With my present system what do l need to hear MQA through my speakers (I understand will only be stereo?).
Have you tried a PC with digital out connected to your SE speakers then a Tidal and Roon subscription - Roon running on that PC will give MQA decode, SE speakers with latest firmware now does the rest I believe.
Zero cost for a trial if you have a suitable PC/laptop/.../ although you may need something like an Explorer v1 to get audio from PC via USB - other USB/SPDIF converters available. Similar to what you might already do with your Prime?
