Denon AVR-X4100W vs Onkyo TX-8270 – that is a question.
The number of channels for receivers is different - 7.2 versus 2.0, respectively, for devices. In terms of power, there are differences, the AVR-X4100W has such a ratio W/Ohm - 125/8, 165/6, while the TX-8270 has a power of 160/6. The value of total harmonic distortion is also different, and for the AVR-X4100W it is 0.05%, but for the TX-8270 it is 0.08%.
The manufacturer installed different DACs, the AVR-X4100W received the model 192 KHz/24-bit, but the TX-8270 is equipped with AK4438 384 KHz/32-bit. The Bi-amping function is implemented only in the Denon AVR-X4100W. Both Denon AVR-X4100W and Onkyo TX-8270 can transmit an audio signal directly to the amplifier and bypasses any DSP processing. Each of the receivers has a Bluetooth connector. Both devices can work with such Apple Music services: AirPlay. Access to the Spotify service is on each of the competitors. The number of available streaming services varies for receivers, the Denon AVR-X4100W works with Pandora, SiriusXM, but the Onkyo TX-8270 works with Deezer, TIDAL, TuneIn Radio.
Support for the HDR function can only boast of the TX-8270. The quality of 4K/60Hz signal remains unchanged when transmitting from a source to a TV or projector via HDMI for both receivers. HDMI signal transmission in standby mode can provide only the AVR-X4100W. Video scaling is only possible with the AVR-X4100W. Each of the participants of the comparison has a Dolby Vision.
The number of HDMI inputs/outputs varies depending on the receiver, the AVR-X4100W has 8/3, and the TX-8270 has 4/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the AVR-X4100W and the TX-8270. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. Like most receivers, our models have a built-in phono stage for connecting a vinyl player.
Unlike the AVR-X4100W where 3 Multi zones is provided, the TX-8270 works with 2 Multi zones. Voice control of the basic functions of the receiver is not realized in both models. There is an ECO mode in AVR-X4100W. The Denon AVR-X4100W and the Onkyo TX-8270 can be properly configured using the setup assistant.
A Dolby Atmos multichannel audio format is available only in the AVR-X4100W. A DTS:X surround technology is not supported by devices from our comparison.
