Q If I use an Apple TV 4K with an AV receiver, is it possible to route the surround sound to headphones? I ask because I’m viewing using a computer monitor and the only way I can get sound is through headphones. —H.G. Fernand, via email

Q I own an AV receiver but don’t ever listen to broadcast radio. In the future, I’d like to just buy a multichannel integrated amp with no AM/FM tuner, but if those exist they are few and far between. Do people still really use the radio on their systems? —Dave Black, via email

A Given the wide range of analog and digital sources you plan to use in your system, I’d definitely recommend buying a separate multichannel speaker system or a passive soundbar with surround speakers and a powered subwoofer to connect to the Denon receiver.

Q I’m upgrading my home theater for Dolby Atmos and have noted that various speakers are now being specifically marketed for this purpose. For example, I’ve seen compact speakers with sloped, downward-pointing baffles that are designed to be wall-mounted near the ceiling. Are these as effective in delivering overhead effects as an in-ceiling or Atmos Enabled speaker? Also, could an Atmos Enabled speaker be mounted in the same manner near the ceiling? —R. Hatton, via email

Q I’ve got a decent Velodyne subwoofer that I’d like to connect to a powered soundbar. Most soundbar manufacturers now use wireless subwoofer connections, however, so I’m struggling to find one that’s capable of connecting with my sub. Could you recommend a mid-level or a high-end soundbar that features a hardwired subwoofer output? —Jim O’Hara, via email

QWhen researching DACs, I ran across the Cambridge Audio CXN, a network audio player that upsamples all inputs to a 24-bit/384kHz hi-res format using “polynomial curve fitting interpolation.” This seems to be the only DAC that offers that kind of feature. Most Ultra HDTVs and Blu-ray players also provide upscaling, but for video. In my experience, this is a very effective feature that improves the experience of watching a regular DVD. Here’s my question: Does audio upsampling have the same effect as video upscaling? —Mike Yang / via e-mail

Q I have searched extensively for an HDMI splitter that will let me connect a high dynamic range source to both my new Dolby Vision-capable Vizio TV and my legacy Anthem receiver (for lossless audio). Oppo’s UDP-203 Ultra HD Blu-ray player has dual HDMI outputs and supports Dolby Vision. It also has an HDMI input that would enable passthrough of another HDR-capable source like a Chromecast Ultra, Roku Ultra, Fire TV, or Apple TV 4K. Here’s my question: Is there a less expensive option than the Oppo that would deliver the same result? —Andy Lutz / Houston, TX
