Assuming you connect to your pre/pro via a digital connection, I don’t see an advantage to the BlueSound
So, again, it comes down to the interface on both the hardware and software. Without actually using both apps I can’t say that one is superior. So based on that I wouldn’t be able to justify the $150 premium for the BlueSound.
Something worth considering ... for me the ability to have a single source playing throughout the house, and being able to easily control it from my phone or tablet (or even by voice via Alexa) has been addicting. If you think this may appeal to you, and that you’ll add additional receivers for other systems, or smart speakers in rooms without a system (the kitchen and bedroom for example) consider that your buying into an ecosystem. These systems don’t work across brands.
There are devices which use the DTS Play-Fi platform which does work across brands. But in my experience the Play-Fi experience isn’t as good as 1st party platforms.
