Pioneer VSX-934 vs Onkyo TX-NR686

Pioneer VSX-934 review

Looking at both of these models it comes obvious that they have not only identical channel quantity (7.2) but also equal power output. Each of them has 165W at 6 Ohms. DTS Neural:X and Dolby Surround technologies produce up-mix (surround emulation) for 2D audio formats. The receiver is equipped with the MCACC multi-channel acoustic calibration system, which makes it easy to set up your home theater audio system. Phase control technology sets the subwoofer more precisely, while Reflex Optimizer (Reflex Optimizer) improves speaker performance with Dolby Atmos.

Onkyo TX-NR686 review

The accuracy and detail of the sound, which is unusual for equipment of this price category, are provided by the 32-bit / 384 kHz Asahi Kasei AK4458 DAC and Onkyo's patented Vector Linear Shaping Circuitry (VLSC). The latter also eliminates noise and interference at high frequencies, which provides very clear articulation of vocals and the precise sound of a number of effects. Moreover, all this is achieved regardless of the format of the played files, whether it be compressed music or high-resolution audio (AIFF, FLAC, WAV, DSD and ALAC up to 24 bit / 192 kHz). It doesn’t really matter if they are received from the network or via the USB port on the back of the receiver.
