Onkyo TX-NR737 black

Experience THX-certified surround sound with the TX-NR737, the most powerful A/V receiver in its class and the best equipped for the future. With a large high-current transformer, a separate inverted three-stage Darlington amplifier circuit, and a highly rigid structure, this heavyweight delivers flawless cinema sound that will shake your walls. It features 4K/60Hz HDMI inputs for gaming and Ultra HD video at 60 frames per second, and supports the HDCP 2.2 standard.

Qdeo 4K upscaling video conversion technology is also included, allowing you to enjoy DVDs and older games in high definition. Music lovers are offered a wide selection of online music services, and can stream nearly all compressed 192 kHz/24-bit, high-resolution, and lossless file formats (including 5.6 MHz DSD) from compatible networked devices using the built-in Wi-Fi and free Onkyo app. Bluetooth is also included as standard. By combining these features with perfect sound quality and an easy-to-use user interface, the TX-NR737 delivers unparalleled studio-quality entertainment at an affordable price.
