Pioneer VSX-531 vs Integra DTM-6 review
It makes sense comparing Pioneer VSX-531 vs Integra DTM-6 because they both are able to give some premium features.
Amplifier
A significant difference between the receivers in the number of channels, Pioneer VSX-531 has 5.1 versus 2.0 for Integra DTM-6. Regarding power, then VSX-531 has such a W/Ohm ratio - 80/8, 140/6 when DTM-6 has a power of 80/8. The THD is the same and is 0.08%.
Audio features
Characteristics of digital to analog converter (DAC) are different, 192 KHz/24-bit for VSX-531 and AK4438 384 KHz/32-bit for the DTM-6. None of the models support Bi-amping. The Pioneer VSX-531 can transmit an audio signal directly to the amplifier and bypasses any DSP processing. Rivals from our review have Bluetooth support. Only the DTM-6 supports Spotify.
Video features
Only the Pioneer VSX-531 has support for High dynamic range (HDR). Only the VSX-531 provides HDMI signal transmission in standby mode. Both competitors are not able to scale the HDMI signal. The HDR standard - Dolby Vision is not supported by these receivers. Only the VSX-531 supports HDMI Audio Return Channel (ARC). Unfortunately, HDMI eARC is not available on monitored devices. Of the two receivers in our comparison, HDMI CEC is present in only the VSX-531. The DTM-6 has a built-in phono stage for connecting a vinyl player. An ECO mode is only available for the VSX-531. Unfortunately, the setup assistant is not available in each of the models.
Multichannel surround
None of the rivals equipped with Dolby Atmos multichannel audio decoder. The receivers do not support the surround sound technology DTS:X.
