Best praise vs top criticism for KEF R3 Meta

Best Praise

+20 pts

“I don't know where some of these comments are coming from. The R series is a whole other level from the older 2.5 way Qs. Either the R3 or the R5 would suit. Personally I'd opt for R3s on stands. I am personally a big fan of bookshelves, though. Offloading that low end duty the the sub(s) really gives room to open up the mids and highs on the bookshelves. I am running R3s currently and I could not be happier with them. I have also spent a lot of time with Q950s. IMO there is really no comparing the two. Completely different class of speaker.”

“The R3 for side surround is extremely unnecessary as those channels don’t need a high end speaker. I’d say if you could return the R3s and get Q350s instead, and use the saved money towards a second subwoofer that would make a demonstrably better difference in experience for your home theater. Other than that, great job! And yeah, pull that couch in a couple of feet closer. You’re beyond the optimal resolution.”

“I appreciate this review because I did consider picking up a $700 990D or $999 990F before I bought my Sonos system. It's wild to think but the return policy on the Samsung's (those deals I mentioned were Samsung and Woot) sounded not so great. I was willing to spend more to try the Sonos, since I knew I could return it. I got the Ultra and Sub4 from Costco and 2 Era 300s from Best Buy. I have a challenging room because of the vaulted ceilings, etc. However, the Ultra, Sub4, and 300s actually sound good in there, where nothing else has. I'm glad I didn't gamble with the Samsung as I don't think it would have been as good. Now I've ordered a second Sub4, hoping that gives me another small boost in quality and of course, removes those dead zones I have with just one sub.”

“Keep in mind that much of the point in getting the 300s would be spatial audio wich again they won't support in your preferred format. Also the Samsung is very well regarded. Seems like an easy decision really.”
