Q I’m using the built-in apps on my Sony XBR-55X850C TV for video streaming. The set’s optical digital audio output is connected to an older Denon AVR-4306 receiver. My problem is that I only get Dolby Digital 5.1 sound from the TV’s Netflix app; no other app (HBO Now/Go, Sony Crackle, Hulu, or Disney+) provides DD 5.1. My local AV shop suggested using another streaming device or upgrading to a high-quality optical cable. Any advice or suggestions? —Ken Ashlock, Colorado Springs, CO

THE VERDICT
The Avalon G4 may be designed for upgrading systems to the new immersive audio formats, but it's also a fine performer that's flexible enough to satisfy other configurations.

Four may be an even number, but a four-channel amplifier like AudioControl's Avalon G4 might seem like an odd duck to some. With Dolby Atmos and other immersive audio formats becoming more common in the custom install market (where AudioControl, which manufactures products at its Seattle facility, has a heavy presence), however, upgrade-anxious customers will obviously need four additional amp channels to complement the company's existing 5- and 7-channel designs.
