Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Streaming Hardware with Roon Application Roon 1.5 is here, c/w MQA software decoding

Sorry for the basic questions here:

1)
What the difference between decode and rendering for the Meridian devices?
Is decode just a decode of the MQA stream in a particilar device?
And rendering is to use the DSP engine in Roon?

2) What can the ID40 card do now?

3) What can the 218 do now?

I use non SE DSP8000.2 speakers.
