Help in streaming for Devialet 120

[lal99]

Hello,
At present I am using sonic transporter as roon core and I use a fiber optic cable with SFP module and use a 6 inch ethernet cable
to connect to router and Devialet 120. At present I use the ethernet ports on router from my internet service provider.
I read using a better switch will provide improvement. Gigabit ethernet switch doesnt work with Devialet 120?
Can you guys recommend a good Ethernet switch which is not super expensive?

Thanks
Rlal
