What is better - Denon AVR-S540BT vs Denon HEOS AVR?
The number of channels for receivers is different - 5.2 versus 5.1, respectively, for devices. In terms of power, there are differences, the AVR-S540BT has such a ratio W/Ohm - 70/8, 90/6, while the HEOS AVR has a power of 50/8, 65/6. The value of total harmonic distortion is also different, and for the AVR-S540BT it is 0.08%, but for the HEOS AVR it is 0.05%. None of the compared opponents supports Bi-amping. The model HEOS AVR can transmit an audio signal directly to the amplifier and bypasses any DSP processing.
Wireless Internet connection via WIFI is only possible with HEOS AVR. Each of the receivers has a Bluetooth connector. Support for Apple Music Services not implemented. Access to the Spotify service is on each of the competitors. The number of available streaming services varies for receivers, the Denon AVR-S540BT works with TIDAL, Pandora, but the Denon HEOS AVR works with Deezer, TIDAL, Pandora, Napster, SiriusXM, TuneIn Radio, iHeart Radio, Sound Cloud.
Support for the HDR function can only boast of the AVR-S540BT. The quality of 4K/60Hz signal remains unchanged when transmitting from a source to a TV or projector via HDMI for both receivers. Signaling over HDMI in standby mode can provide the AVR-S540BT and the HEOS AVR. None of the devices can increase the resolution of the incoming video signal. Operation with the Dolby Vision is only possible with the AVR-S540BT.
The number of HDMI inputs/outputs varies depending on the receiver, the AVR-S540BT has 5/1, and the HEOS AVR has 4/1. HDMI Audio Return Channel is implemented in both devices. HDMI eARC is not supported by the AVR-S540BT and the HEOS AVR. When comparing receivers, it becomes clear that each of the rivals can work with HDMI CEC. AVR-S540BT and HEOS AVR support the standard HDCP 2.2. Unlike most receivers, our models do not have a built-in phono stage for connecting a vinyl player. There is an ECO mode in AVR-S540BT. The Denon AVR-S540BT can be properly configured using the setup assistant.
