I sought further clarification ...
Let’s focus on the SpeakerLink output from the 218. In its basic terms the 218 will decode to ‘MQA core’ ready for transmission via SpeakerLink. In the case of the M6, it will receive this audio signal (via MHR) and play the 24/96 or 24/88 MQA signal. If however you have a Special Edition (SE) Meridian DSP loudspeaker, it will then have the ability to render the signal to a higher resolution as the SE loudspeaker is able to achieve this.
As you can see in both instances MQA is being played back so you will benefit from MQA in either scenario. Yes it’s true that you will receive higher performance from SE loudspeakers but you are also receiving a better audio transmission on non-SE Meridian loudspeakers, thus utilising the benefits of MQA when using a 218.
You are always subject to the capabilities of any audio system but it’s certainly worth remembering that Meridian Loudspeakers have been designed to work as a highly tuned, high performing system. We ensure the components used in our electronic and loudspeaker design compliments the final product as a complete package. The DSP is carefully crafted to suit its requirements and the hardware it is driving allowing you to enjoy the music.
The further question he couldn’t answer for me: on my Mac Mini what would be the result of Amarra4 Luxe’s initial MQA unfolding to the 218 (via Meridian 210), to the M6.
