I will put my money on the LS50 w2. In all probability the wireless will sound better than the passive combo mentioned above. Plus you get some flexibility to tweak the settings to suit your preferences. You can later add a quality sub to take the system to a whole new level. Reliability of an active system is on par with or better than passives because you are protected from overdriving your amp or speaker unless it's a DIY active speaker. I have been using actives for almost 10 years without any issue.LS50 meta + Marantz PM8006 + wireless streamer (or) LS50 wireless ll
