Performance

Audio Quality

At the heart of any AV receiver is its ability to deliver pristine, powerful sound—and the TX-SR393 doesn’t disappoint. With 155 watts per channel, the receiver is more than capable of driving most bookshelf and tower speakers for an authentic surround sound experience.

When paired with Dolby Atmos or DTS:X-enabled content, the receiver delivers a spatially rich, 3D-like soundfield, allowing effects like raindrops, gunfire, or aircraft to move convincingly around the room. Even without dedicated height speakers, the Dolby Atmos Height Virtualizer creates a simulated vertical presence that adds depth and immersion, especially in smaller spaces.

Video Passthrough and HDR Support

The TX-SR393 fully supports modern video standards. With passthrough for 4K/60p, HDR10, Dolby Vision, HLG, and BT.2020 color, it ensures compatibility with all major streaming platforms and UHD Blu-ray discs. This makes it a solid video switcher for multi-source entertainment centers.

Bluetooth Streaming

Streaming via Bluetooth is seamless once paired. The device automatically connects with known devices and initiates playback, a feature that enhances everyday usability. While it doesn’t support advanced wireless codecs like aptX HD, casual listeners will find the audio quality satisfactory, especially with the Advanced Music Optimizer engaged.

Room Calibration with AccuEQ

The AccuEQ system is a standout inclusion for the price. It automatically detects speaker distance, type, and output levels, then applies tailored equalization. The added Subwoofer EQ ensures that bass response is optimized for room acoustics. For those running a Dolby Atmos setup, the AccuReflex feature aligns phase timing for height channels, preventing audio artifacts like echo or delay.
