I’m constantly on the lookout for quality, low-cost electronics that have a lot in common with higher priced models and brands. What a pleasant experience trying out and comparing the Onkyo TX-SR373 to other entry-level AV receivers. Home theater systems are only as good as the AV receiver behind them because it is what delivers audio and video processing. The latest 4K HDR TV requires signal compatibility. Onkyo does not disappoint with the Onkyo TX-SR373, but continues to show why they are known for quality Hi-Fi components and home theater systems.

About the Product

At a suggested retail price of $349, the Onkyo TX-SR373 is an economical way to acquire a receiver to use as the hub for a second room system. The 5.2-channel AV receiver delivers 155W power output per channel. System calibration is included with this lower range product, as well as wireless connectivity and HD sound formats compatibility. There’s no need to sacrifice the quality of Dolby TrueHD or DTS-HD Master Audio. The delivery is commendable.

One of my favorite features is the self-explanatory rear connection panel. There’s no need to skip a desired feature for this system because of questions about what goes where. Each connection has an easy-to-see image displayed against a gray panel showing what types of devices plug into it. It waves away concern about harming the system by connecting the wrong piece of equipment.

The first home theater receiver system a person undertakes should be a pleasant experience. The TX-SR373 has an illustrated speaker layout diagram makes setup easy and results in excellent sound delivery.

Four HDMI inputs support HDR10, HDCP 2.2 and 4K video transmission at 60p. Two composite video inputs are also available for:

  • Digital optical input
  • Older devices
  • AM/FM radio tuner

A small price-tag still delivers a lot of performance! 80 Watts-per-Channel (WPC) fit the sound level I was seeking. Sound is a personal matter, but the dynamics and resonance should please most people. Dolby TrueHD/DTS-HD Master Audio decoding is another feature of the TX-SR53. The system also includes HDR, 3D, Audio Return Channel, 1080p, and 4K pass-through via its 4 HDMI inputs and one output.

Use the built-in Bluetooth for direct streaming from compatible tablets and smartphones with the built-in Bluetooth. A front-mounted USB port provides easy setup and access to the myriad of music files most of us have hanging around the house stored on flash drives.

Favorite Feature: A pleasant surprise with the Onkyo TX-SR373 5.1 channel AV Receiver is the inclusion of AccuEQ Room Calibration. After analyzing the room with its included microphone, speaker distance is set according to the listening position. It further adjusts output, selects subwoofer crossover and completes audio equalization.

It’s common for manufacturers to keep significant upgrades to mid and top level range. Offering the technology in the TX-SR373 adds an extra reason to select the lower-priced unit as a first or add-on receiver.

Comparison with the Previous Model Onkyo TX-SR353

The entry-level TX-SR353 has excellent upgrades that made it a popular choice for 2016 and have carried on to the 2017 model. Both models are powerful and provide full support for 4K video and decoding for Dolby TrueHD and DTS-HD Master Audio compatible to Blu-ray discs. The TX-SR373 displays the user-friendly, simple to read labeled and redesigned rear panel introduced last year and features legacy composite inputs for devices like the Nintendo Wii and VCRs. Other game consoles continue to be supported and produce an exciting experience for gamers. An upgrade reinforces the company’s amplification philosophy of controlled power. Discrete analog amps remain from last year’s model, rather than the use of an all-in-one integrated circuit. Dynamic audio reproduction results in high instantaneous current to the speakers. AccuEQ Room Calibration technology in the 2017 entry-level TX-SR373 increases sound set-up and quality at a low price.
