It’s strongly recommended to compare different receivers if you want to choose the best one: Onkyo TX-SR353 vs Onkyo TX-SR444.
The number of channels for receivers is different - 5.1 versus 7.1, respectively, for devices. In terms of power, there are differences, the TX-SR353 has such a ratio W/Ohm - 140/6, while the TX-SR444 has a power of 100/6. A common feature for devices is the same total harmonic distortion - 0.08%.
The manufacturer installed different DACs, the TX-SR353 received the model 192 KHz/24-bit, but the TX-SR444 is equipped with TI Burr-Brown 192 KHz/24-bit. None of the compared opponents supports Bi-amping. The model TX-SR444 can transmit an audio signal directly to the amplifier and bypasses any DSP processing.

The number of HDMI inputs/outputs is the same - 4/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the TX-SR353 and the TX-SR444. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. TX-SR353 and TX-SR444 support the standard HDCP 2.2. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player. Voice control of the basic functions of the receiver is not realized in both models. There is an ECO mode in neither AV receiver. None of these units can be properly configured using the setup assistant.
A Dolby Atmos multichannel audio format is available only in the TX-SR444. A DTS:X surround technology is not supported by devices from our comparison.
