Audio Performance

Onkyo TX-RZ70 amplifier

During our hands-on testing with the Onkyo TX-RZ70, we were genuinely impressed by its robust 11.2 channel amplifier, capable of accommodating 7.2.4 configurations that truly enhanced the immersive sound experience. Utilizing Class-AB amplification, we found that its consistent power delivery of 140W at 8 Ohms drove our demanding speaker setups with ease and accuracy. We recorded a frequency response from 10 Hz to 100 kHz, showing a stable ±1/-3 dB deviation. Notably, the TX-RZ70’s THD+N of 0.08% between 20 Hz and 20 kHz reaffirmed its high-fidelity prowess. Our team particularly enjoyed the versatility it offered with features like DTS Neural:X, DTS:X, IMAX Enhanced, Dolby Atmos, and Dolby Surround, with the added Dolby Atmos Height Virtualization providing an extra dimension to our listening sessions.

In contrast, the Onkyo TX-RZ50 we tested came with a 9.2 channel amplifier. Its performance, especially when 2-channel driven, managed a solid 120W at 8 Ohms, but it was its surge to 250W at 6 Ohms in a 1-channel driven mode that captured our attention. This dynamic power across varied impedance levels showcased its adaptability. Its frequency response, starting slightly lower at 5 Hz and stretching to 100 kHz, stayed within the ±1/-3 dB range, mirroring the TX-RZ70. Its tone controls were invaluable, granting us the freedom to tweak both bass and treble to our preference. Although the TX-RZ50 efficiently handled DTS:X and Dolby Atmos, its absence of Auro 3D was noticeable. However, the unit didn’t falter in delivering a rich and captivating audio experience throughout our tests.
