With MQA into SE loudspeakers, it sounds sublime. But then again, I am very sure that the output from the 218 will be *identical* to the output of the 818v3 in this scenario. The rest of the magic is the rendering in the SE loudspeaker hardware.
Again, for MQA decoded into DSP loudspeakers which are capable only of 96/24, it is my understanding that the decoded MQA core is always 2x sample rate, so again, the output of the 218 and 818v3 should be the same.
For non-MQA, it's up to our ears, and I have no opinion at this time.
