I have a Bluesound Vault 2i in my second system and an Aurender N200 in my main system.
Both have been great, the Aurender is 4x more money but the build quality and support are top notch. The Vault has been pretty much flawless in the 6 years I've owned it.
Bluesound is the best platform for those new to streaming in my opinion. Hard to beat for the money.
