No experience with the Wyred4Sound Remedy but I do have their Sonos Connect with “upgraded” digital output. It’s similar to the Remedy, but built in. I did not notice any improvement with my gear so I tried to return it within one week. It’s NOT a “no hassle” guaranty. They convinced me to not return it in order to let it burn in. By the time I finally realized there was no burn-in improvement, it was past their return policy. They refused to honor the fact that I had asked for a return within one week of receiving it and only kept it longer due to their insistence. Expensive lesson.
You never know what components will do (improve or degrade) your sound until you try them out. Just make sure there’s a fair return policy. This is the reason I recently became a PS Audio customer. There was no risk in trying out their products. Fortunatelly, I’m extremelly happy with my purchases, so everything’s a keeper.
