Differences between MinimServer & BubbleUpNp server

[adhara]

Hi there,

1st point:
I have both Minimserver and bubbleupnp server installed on my Synology NAS.
We often see end users install both of them on their device.

I use MConnect (or bubbleUpNp) as player on my smartphone to play music to my DAC (chromecast builtin).

If I stop BubbleUpnp server on my NAS, I see no difference, everything works fine.

So what is Bubbleupnp Server software for?

2nd point:
I'd like to improve listening experience quality.
Some end-users have a SOTM SMS 200 NEO.. Who is able to say how adding this device can improve my listening experience ?


currently:
NAS (minimserver/minimstreamer) ---> Chromecast (on my WISA hub (it s like a DAC)) --> hi-fi speakers

plan:
NAS (minimserver/minimstreamer) ---> SOTM SMS 200 NEO --> Chromecast --> hi-fi speakers
