Sony STR-ZA2100ES was introduced in 2017. It is equipped with 7 channel amplifier and is capable of 9ch + Phantom 2ch maximum channel processing.
We evaluated the Receiver and gave 50 overall score out of 100. Our ranking system is based on the amplifier specifications, audio and video features, connectivity, multizone capabilities, radio and many other details.
Amplifier score is based on power ratings, minimum impedance load, power supply, transformer type, total harmonic distortion, damping factor, signal to noise ratio and other small details. Audio score depends on the number of channels, front wide channel support, maximum channel processing, support of audio formats, DAC specifications, room calibration algorithm... Video score is based on HDR, Dolby Vision and video signal passthrough and upscaling, analog to HDMI upconversion. Connectivity score is defined from all wired and wireless inputs and outputs, internet and bluetooth connections, HEOS, SONOS and others. Multizone score depends on the number of zones with their outputs. Radio score is evaluated form digital radio support and analog tuner with its frequency range, signal to noise ratio, harmonic distortion...

Sony STR-ZA2100ES has 7 channel amplifier and delivers 75 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
The Receiver has 4K passthrough up to 60p and 4K upscaling up to 60p. It can bypass HDR10, Dolby Vision.
High-dynamic-range (HDR) video has greater dynamic range than standard-dynamic-range (SDR) video with brigter whites and deeper blacks. HDR10 was announced on August 27, 2015, by the Consumer Technology Association and uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports up to 1000 nits of brightness and 10-bit color which corresponds to 1024 shades of the primary RGB colors.
Dolby Vision is an update to HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to 10,000 nits maximum brightness on a scene-by-scene or frame-by-frame basis and supports up to 12-bit color depth (4096 shades of RGB) and 8K resolution.
Dolby Atmos and Dolby Surround upmixer
Sony STR-ZA2100ES supports Dolby Atmos with its Dolby Surround upmixer. It can be configured upto 5.1.2 channels using internal amplifiers or upto 7.1.2 or 5.1.4 channels by adding 2 channel external amplifier.
Dolby Atmos is the first cinematic audio format in which sounds exist as individual entities, called audio objects. In Dolby Atmos, any sound - the helicopter, a car screeching around a corner, a melodic bird call - can exist as an independent audio object, free of channel restrictions. They can be precisely placed and moved anywhere in your room, including overhead, to flow above and around you in three-dimensional space. Through the use of audio objects, overhead sound, and all the richness, clarity, and power of Dolby sound, Dolby Atmos turns your room into an amazing place for entertainment. You'll feel like you're inside the action, in ways you've never experienced before.
Dolby Atmos for the home represents every sound in the original cinema mix as an audio object. Extensions to the Dolby Audio™ codecs, along with an advanced scalable algorithm, allow Dolby Atmos to be delivered via Blu-ray Disc and streaming media. A spatially-coded substream is added to Dolby TrueHD or Dolby Digital Plus. A Dolby Atmos audio/video receiver (AVR) adapts the cinema experience to your home theater from seven speakers to as many as 34 in 24.1.10 configuration, recreating the original artistic concept. The format supports up to 128 simultaneous independent audio objects in a mix for rich, realistic, and breathtaking sound. It recreates the director's original concept through descriptive metadata to provide customized playback for home theater and delivers sounds above you through overhead speakers, special upward-firing Dolby Atmos speakers, or a Dolby Atmos enabled sound bar.
If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.
DTS:X and Neural:X upmixer
Sony STR-ZA2100ES supports DTS:X with its Neural:X upmixer. It can be configured upto 5.1.2 channels using internal amplifiers or upto 7.1.2 or 5.1.4 channels by adding 2 channel external amplifier.
A technique used in DTS:X is similar to the one used in Dolby Atmos. Instead of a fixed number of channels, DTS:X defines object locations from the listener in polar coordinates. An a/v receiver then dynamically renders sound according to the current speaker configuration. The speaker layout employed by DTS:X is the sum of Dolby Atmos and Auro-3D. It has standard 7.1 channel base layer, a 5 channel height layer above the base layer on the front and side walls, and 3 rows of speakers on the ceiling.
DTS Neural:X is a new upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
Digital Legato Linear
Sony STR-ZA2100ES features Digital Legato Linear (D.L.L.) to play audio signals with high-quality sound. The D.L.L. function is a technology developed by Sony that allows low-quality digital and analog audio signals to be played with high-quality sound. This function is available for Linear PCM signals, as well as lossy compression audio formats and analog audio signals. It works when [2ch Stereo], [Direct], [A.F.D.] or [Multi Stereo] is selected.
Sony STR-ZA2100ES comes with D.C.A.C. EX room correction system and includes the calibration microphone.
Sony STR-ZA2100ES can be connected to internet using ethernet cable. It has 6 HDMI inputs and HDCP 2.2 (6 in / 2 out) copy protection. There are 2.2 (Height L/R and Subwoofers) channel analog pre-outs for external amplification.
Front panel has HDMI and USB inputs.
