I have a pair of LS50 Meta’s, am interested in a Sub, what are you guys using and experience using the WiiM Amp, and connectivity, using the settings of the Sub Out how do u find it “offloads” the Mains which i would assume would benefit the WiiM Amp at the low end, vs the recommended full range speaker out from Rel. realize will be lots of variations depending on mains, my shortlist - Rel Tzero certainly good budget option, SVS 3000 Micro or Kef KC62 but expensive, oh i don’t want larger (e.g Rel 5X) I like clean / tight bass and must come in White. Room is Medium 5m x 4m. I have listened to both Rel and Kef as although i heard lots of issues with KC62 but with LS50W2. Thanks for any Thoughts
