What do I need to use DSP with MQA

[wklie (Peter Lie)]

For MQA DSP in Roon, you need a MQA renderer or a MQA DAC that supports rendering operation from a MQA Core 88.2/96kHz signal. Some Full MQA DAC, especially early models, did not suppor that. Some required firmware upgrades.

That was a list I made before, but it is outdated, and there is a complication that certain firmwares for certain models have serious bugs:

List of Roon compatible MQA Renderers

With Roon 1.5 MQA, it’s rather desirable for a MQA DAC to be able to render the MQA Core signal (first unfold) with or without DSP applied. I’ll start with a list of devices that I know to be working, and let others add other devices. Some MQA Full Decoder DAC can accept the MQA Core signal from Roon 1.5, some cannot. For those that do, setting their MQA Capabilities to “Decoder and Renderer” or “Renderer only” should work. Here’s a list of MQA Full Decoder DAC that are known to work: Lumi…
