The integration between the Trinnov, 271 and DSP speakers is seemless (just the same as using the 861). You can control the volume in the Trinnov as Bruce said or you can have a fixed volume setting in the Trinnov and control the system volume in the speakers. That’s what I do using the MSR+ remote - same as you do with the 861.

The only inconvenience is that the speakers and the Trinnov volume both will respond to the MSR+ Remote. You can fix the volume control in the Trinnov so it won’t increase but you can’t stop it from decreasing so you need to be careful where you point the remote when you lower the volume. It’s just a minor issue for me but others may find it more annoying.

I’m not sure if there are any difficulties when controlling the volume in the Trinnov instead of the M DAP speakers - maybe Bruce can answer that.

I use a 218 connected to the 271 via SL for full fat MQA. I also have another 218 connected into my Trinnov via SPDIF and can play Sooloos etc. through that (including MQA via Tidal ) but that isn’t full fat MQA - I think. I haven’t compared the 2 yet (in case anyone asks) to know which I prefer.

I’m sure there will be some differences as my speakers will not be “EQ’d” going directly through the 271 and bypassing the Trinnov.
