Pioneer VSX-531 Home cinema Receiver
  • Great value for a five channel AV amp with little competition if you want a top brand.
  • Excellent piece of kit. Great sound quality on all channels. Pioneer still number one in the sound industry.
  • More than enough power, and no static noise whatsoever. I recommend this AV receiver.

  • Great piece of equipment, but has a tendency to just turn itself off when it has been on a few hours.

What customers say about "Features"
Denon AVR-X550BT 5.2 Av-Receiver 5x130W Black 4K UltraHD, Bluetooth, USB
  • Very clear sound. In combination with JBL all sounds amazing. Highly recommend this product.
  • The unit has strengths such as HDR10, Dolby Vision, Hybrid Log Gamma, 4K passthrough and bluetooth. That's is pretty enough for a good home cinema.
  • The Receiver has 4K passthrough up to 60p. All other shortcomings are covered by auxiliary peripherals.
  • I can not choose sound mode, it only plays what the video supports so youtube videos I can't listen in good quality.
  • For the year of release it doesn't support Dolby Atmos. It's a little disappointing.
Pioneer VSX-531 Home cinema Receiver
  • Replaced my old Pioneer receiver with this to pair it with new 4k tv. My initial reaction was wow.
  • Superb amplifier great price lots of features at a great price.
  • More than enough power, and no static noise whatsoever. I recommend this AV receiver.
  • Sound is amazing. I recommend this receiver.
  • Bought it for the brand goodwill but kind of disappointed, the sound is not rich enough and lack of update technology.

What customers say about "Connectivity"
Denon AVR-X550BT 5.2 Av-Receiver 5x130W Black 4K UltraHD, Bluetooth, USB
  • I can use USB on the front to fast connect flash drive with my recroding from camera.
  • Nice that it can stream music, movies from phones, tablets, etc with built-in bluetooth connection.
  • It is fully synchronized with the TV (if there is an HDMI connection): on / off, volume control. Plenty of connectivity options at the good price.
  • Upset that it only comes with spring clip speaker connections not binding posts.
  • The unit does not have Wi-Fi or even ethernet. It's 2018 product. It's just impossible.
Pioneer VSX-531 Home cinema Receiver
  • Build quality feels good. As well as all the Dolby settings and 4k hdr it also supports Bluetooth.
  • Great av receiver that looks smart and has a great sound quality, Bluetooth to connect your phone ect to, would definitely recommend.
  • Worked out of the box, bluetooth included. We now have surround sound, jay!
  • It a terrific bit of kit. Sounds superb. And the bonus of Bluetooth connection too well and i truly happy.
  • The built-in Bluetooth did not connect to any of my devices, I'm not sure why. Probably it's the end-devices but it's still a bit of a bummer.
