It’s strongly recommended to compare different receivers if you want to choose the best one: Denon AVR-A1H vs Denon AVR-X1500H.
The number of channels for receivers is different - 15.4 versus 7.2, respectively, for devices. In terms of power, there are differences, the AVR-A1H has such a ratio W/Ohm - 150/8, 190/6, while the AVR-X1500H has a power of 80/8, 120/6. The value of total harmonic distortion is also different, and for the AVR-A1H it is 0,05%, but for the AVR-X1500H it is 0.08%.
Competitive models use the same DAC. Each of the compared opponents supports Bi-amping. Both Denon AVR-A1H and Denon AVR-X1500H 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, AirPlay 2. Access to the Spotify service is on each of the competitors. The number of available streaming services varies for receivers, the Denon AVR-A1H works with Deezer, TIDAL, Pandora, SiriusXM, Napster, SoundCloud, Amazon Music, Amazon Music HD, MOOD:Mix, but the Denon AVR-X1500H works with Deezer, TIDAL, Pandora, Napster, SiriusXM, TuneIn Radio, iHeart Radio, Sound Cloud.
Signaling over HDMI in standby mode can provide the AVR-A1H and the AVR-X1500H. Video scaling is only possible with the AVR-A1H. Each of the participants of the comparison has a Dolby Vision.
The number of HDMI inputs/outputs varies depending on the receiver, the AVR-A1H has 7/3, and the AVR-X1500H has 6/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is only supported by the AVR-A1H. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. The AVR-A1H has support for the standard HDCP 2.3, compared to the AVR-X1500H, which supports the standard HDCP 2.2. Like most receivers, our models have a built-in phono stage for connecting a vinyl player.
Unlike the AVR-A1H where 3 Multi zones is provided, the AVR-X1500H works with 2 Multi zones. Voice control is performed using Amazon Alexa, Google Assistant, Siri, Josh.AI in both models. There is an ECO mode in either AV receiver. The Denon AVR-A1H and the Denon AVR-X1500H can be properly configured using the setup assistant.
A Dolby Atmos multichannel audio format is available both models. A DTS:X surround technology is supported by devices from our comparison.
