I was watching a youtube video by tharbamar about the new metas where he was comparing it to Quad S2 bookshelves. He felt that the new metas provide less than 10% improvement over the old LS50s. His advice was that if you already own the original LS50s, it's not worth selling those and buying new ones. Given that the guy has extensive experience with the older model, and is generally more honest and upfront in his reviews (sort of how Thomas and Stereo and a few other youtubers used to be before they started peddling chi-fi), his opinion has to be taken on its merit. However, Steve Guttenberg, another reviewer who I respect, was all ga ga over the metas. Go figure!
I'm sure that even a 10% improvement is a big deal in our hobby, but the question is if it's enough to sell my LS50 wireless. Hopefully, as more long time owners moving up to the metas chime in the dust will start to settle a bit.
