I’d also like to see this as a feature. Current use case:
Roon to Roon Ready MSB DAC (the single endpoint).
MSB feeds into Pass HPA-1 Headphone amp/Preamp.
HPA-1 feeds Pass amps to speakers. I use the Roon volume control to control device volume on the MSB DAC. This zone also uses a convolution filter for DSP.
HPA-1 also feeds headphones. In this case I use the HPA-1 volume control (so zone volume control would be fixed) and I don’t want the convolution filter.
It is a lot of monkeying around to switch between these two use cases just because I can’t set up the MSB DAC with two different profiles.
