Please let me add this:
My initial Sooloos network configuration was reserved IP addresses by MAC address within the routers DHCP address range for each Sooloos component. It has been this way for years with no issues.
Prompted by reading some threads here, I decided to change the Sooloos components to fixed IP addresses outside of the routers DHCP range. To my total amazement the system sounder better..a lot better. My wife even asked what I did, it was that much improved. More width, separation, tighter bass. This was listening at the exact same volume level before and after. No other changes.
I know Ronnie and Ian will scoff at this but it was a eye opener.
