AV receivers under review have the same number of channels. In terms of power, there are differences, the HEOS AVR has such a ratio W/Ohm - 50/8, 65/6, while the TX-SR343 has a power of 100/6. The value of total harmonic distortion is also different, and for the HEOS AVR it is 0.05%, but for the TX-SR343 it is 0.08%. None of the compared opponents supports Bi-amping.
