Hi. I have a Yamaha RX-V371 receiver with 2 Sony SS-F6000 speakers as fronts. Dialog is a little hard to hear sometimes so I want to get a center channel. But the obvious choice, Sony SS-CN5000 Is no longer available, even as a refurb. There are a few non-Sonys I'm looking at, notably a Polk CS10. Would that work? I'm not the sort of audiophile who would focus on every little change in timbre. Thanks.
