If you want to improve on your USB based sound, then I would start with something like the Uptone Regen or ISO Regen. There are other options as well. W4S. SOtM, etc. etc. etc. This would be from your MacBook. And you will be able to A/B vs the Bluesound via Optical.
If you like the results, then I highly recommend going Tidal via Roon, into a Roon Endpoint. I use the Sonore microRendu. Sonore has just released the UltraRendu. There are also options from SOtM and others.
