Just bought this product and very happy, the depth and richness of the sound compared to my TV audio is striking. Have not tried to create a 5.1 system with it, it does seem that may be a step too far but if i wanted that i wouldnt have bought a soundbar. Very happy, looks good sounds good!

The design of the bar and sub woofer is a winner. It is sleek and doesn't take up too much space on the shelf or floor. The Tech is good too, love the HDMI ARC control. This way i dont have to manage the volume of the TV and Soundbar seperately.. ARC syncs it and i can control both from the TV remote. The Sound quality is good for my needs. I dont need a crazy hi end system and need something for movie nights with kids.. not too loud, but clear and impactful. Recommend it.

The surround group of HW-K651 and two WAM1500 which suppose to give 5.1 surround, disconnected very often, every 5-10 minutes they lost the pairing and reconnected again with annoying beep sound that indicate pairing/unpairing. the FW upgrade didn't help also... Spotify demands premium account to control the soundbar.... Also you can access to Tidal from the multiroom application with limit functionality, not like the offical app of Tidal. No support of streaming/casting audio based on WiFi from smartphone to HW-K651, only bluetooth.
