Has anyone used the new Innuos 2.0 Sense music app? Compared it to Roon?

The fundamental difference between Roon and InnuOS is in philosophy: whereas Roon believes in high powered, complex sound shaping, InnuOS pursues minimalist and purist design: low powered processors and maximum attention to suppressing RMI/EMI and ground level noise intrusion. This has direct implications on software coding: Sense is designed to minimise CPU usage whereas Roon sees CPU usage as uncritical and uses complex plug-ins such as DSP to increase user friendliness.

Very well said @antigrunge2 

I too believe Sense to be better than Roon.   The only feature which tempts me back to Roon is DSP.  We all need a tone control now and then.

I did ask Innuos if they plan to add such a feature, and the reply from Head of Sales was thus:

One of the reasons Sense sounds so good is because it is so light on hardware processing. Put simply, the more processing running in the background, the more noise is generated with negative impact on sound quality. This is why, for the moment, we have no plans to add DSP in Sense. That said, our development team is constantly looking for ways to improve our products, so we may eventually find a way to implement DSP with neglidgeable impact in sound quality.

“Trouble with that is that the more powerful the processor the higher the noise level…”

Exactly! One of the reasons why I prefer Aurender’s Conductor app over ROON. And some folks wonder why Aurender is not supporting ROON :-)

I too switched from Roon to Sense.  One possible solution to your DSP is to just add a miniDSP in your signal path between pre & amp.  Yes yes I know this is an extra A/D-D/A but using the miniDSP-HD version I have been unable to hear the difference noting that I have the miniDSP due to my multi-amplified horn system that that I use the mini for both crossover and volume slope of the multiple amplified horns so that they stay matched at all volumes.
