Personally if it’s in the budget I’d get a Eero Mesh system especially if there’s a good distance/walls between your router and listening room. For extenders this TP Link had some very positive buzz here, and this Netgear extender (might be Mesh) was highly rated by Consumer Reports FWIW, but that’s all I got. Hope this helps.
