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.
