Sound United has announced upgraded versions of the Denon AVR-X8500H and Marantz AV8805 receivers, now with HDMI 2.1. Owners of the old versions will also be able to upgrade to HDMI 2.1 through a kit.
New HDMI 2.1 receiversThe last 6-7 months have been rough for Denon and Marantz, both owned by Sound United. Their first HDMI 2.1 capable receivers were faulty and the company has seemingly given up trying to fix it. Sound United has now announced upgraded versions of the current Denon AVR-X8500H and Marantz AV8805 receivers. The new "A" revisions will come with HDMI 2.1 features that may actually work – at least according to the company. - "The two new units, dubbed the Denon AVR-X8500H “A” and Marantz AV8805 “A” boast many exciting updates, including 8K/60Hz upscaling and passthrough, 4K/120Hz pass-through , HDR10+, Dynamic HDR, HDCP 2.3, as well as other HDMI 2.1 technologies. The factory upgraded Denon and Marantz units will gradually replace all existing Denon AVR-X8500H and Marantz AV8805 units," the company announced. The HDMI 2.1 features will let owners pass through 4K120 signals from PCs and game consoles like Xbox Series X and PlayStation 5 as well as 8K signals from future players and consoles. The receivers also support Dolby Atmos and DTS:X audio. Denon AVR-X8500HA will retail for $4,299 and Marantz AV8805A for $4,799.The new upgraded Marantz AV8805A and Denon AVR-X8500HA AV receivers
Upgrade programOwners of the existing non-A Denon AVR-X8500H and Marantz AV8805 will also be offered the HDMI 2.1 upgrade through a hardware modification kit that will cost $599. - "Current owners of the Denon AVR-X8500H and Marantz AV8805 will have the opportunity to upgrade the HDMI/Digital board within their units to obtain the same features as the “A” components. The upgrade requires a hardware modification at a Denon and Marantz certified Service Center. Beginning June 15, 2021, this will be arranged on request by contacting Denon or Marantz directly via the Denon Site and Marantz Site for US$599 or CA$749," said Sound United.
