I recently auditioned Kef LS50 Meta at ProFx in Bangalore. The pairs were run with Denon PMA900HNE and Polk HTS10 subwoofer. I streamed the songs wirelessly through Apple Music.
Taste-wise, I am a hard-rock fan(ACDC, Guns n Roses, Creed, Korn etc) but I also like to listen to post-grunge(Switchfoot, Relient K, Hinder etc) and alt rock(Audioslave, Greenday etc).
My reaction to this system is mixed. It's a small boxy speaker. The sound coming from it is bigger than the box, but it is still small. YOU MUST NEED A DECENT SUBWOOFER WITH THESE SPEAKERS. If you play good recordings(e.g. chesky recordings) against it, the soundstage and sound imaging will pleasantly surprise you, but once I play my inner-demon songs(ACDC), there's just not enough meat in these speakers. If you love hard-rock, look otherwise.
When I moved to playing pop/pop-rock, it sounded a bit better. Listening "Don't you remember" by Adele was nice, but then again, it was just nice. It didn't touch my heart. Then I played "Mr Brightside" by The Killers, and the same fate follows. All songs were just nice.
If you enjoy listening at low volume, these speakers are for you.
If you enjoy long-time listening with zero fatigue, these speakers are for you.
If you enjoy detail, instrument separation, bigger soundstage, decent sound imaging, these speakers are for you.
It's a clinical awesomemess. It's best kept at clinics. I needed soul.
