Exploring the Most Important Features
Design and Build
While both models adhere to Denon’s minimalist yet elegant aesthetic, it was striking to note their physical similarities and minute differences during our hands-on testing. The AVR-S570BT and the AVR-S660H almost mirror each other, measuring 17.1 × 13 × 6 inches and 17.1 x 13.3 x 6 inches, respectively. Although the AVR-S660H weighs slightly more (17.2 lbs) than the AVR-S570BT (16.8 lbs), this weight difference in hand gave the AVR-S660H a perceived edge in build quality.

The one-line front display on both models gave a clean, uncluttered look, but we did find ourselves longing for a more comprehensive display when navigating through complex settings.
Power Output, Amplifier, and Audio Specifications
In our hands-on testing of both receivers, we closely observed their amplifiers and the power they deliver across their respective number of channels. The 5-channel AVR-S660H holds a slight advantage, delivering 75 watts per channel at 8 ohms, 100 watts at 6 ohms, and a peak power output of 150 watts at 6 ohms for 1kHz at 10% 1ch Drive. On the other hand, the 5.1-channel AVR-S570BT demonstrates a solid performance, pushing 70 watts per channel at 8 ohms, 90 watts at 6 ohms, and peaking at 140 watts at 6 ohms under similar conditions.
Where the AVR-S660H truly shines is in its impressive audio specifications, making it a go-to choice for audiophiles. With its broader frequency response from 10Hz–100kHz and a higher signal-to-noise ratio of 98dB, it delivers a richer, more detailed, and crisp audio experience. The nuanced clarity and breadth of sound it produces genuinely enhances the immersive feel of any home theater setup.
Connectivity
Connectivity is a significant determinant when it comes to integrating an AV receiver into your existing setup. In our assessment, the AVR-S660H surpassed the AVR-S570BT with six HDMI inputs compared to the latter’s four. The inclusion of two composite inputs, a phono input, and a USB port on the AVR-S660H offered additional convenience and flexibility during setup.
Both models, however, came equipped with two analog audio inputs, two digital optical inputs, one digital coaxial input, and two subwoofer outputs. We were pleasantly surprised by the AVR-S660H’s Ethernet and microphone ports, which provide additional options for network connectivity and calibration.
User Experience
Both the AVR-S570BT and AVR-S660H left us satisfied with their user-friendly features. The compatibility with the Denon Remote App made it incredibly convenient to control the receivers using our smartphones. The auto speaker setup by microphone, an intuitive feature on both models, made the calibration process straightforward, helping us tailor the sound to our testing environment.
Power Consumption
Upon monitoring power consumption, the AVR-S660H consumed slightly more at 340W compared to the AVR-S570BT’s 310W. Get the Best Deal on Amazon Today! Both models were impressively efficient in standby mode, consuming just 0.1W. Their ‘No Sound’ consumption ratings are also similar, which is an excellent testament to their energy efficiency.
