Q I’ve always been interested in streaming high-resolution audio through my Denon AVR-4300H receiver, but don’t know if that’s possible. Although I mainly listen to music on Spotify and Pandora, I tried Tidal and Amazon Music HD but couldn’t figure out how to stream the tracks in high resolution. What options do I have, if any? —Mark Levesque, via email

Q My new Denon A/V receiver has an eARC (enhanced Audio Return Channel) HDMI connection, and my TV has a regular HDMI ARC connection. Here’s my question: Will the Denon A/V receiver be able to decode both Dolby Atmos/Dolby True HD and DTS:X/DTS-HD Master Audio soundtracks that are routed to it from the TV’s HDMI ARC port, or do I need to connect sources such as an Ultra HD Blu-ray player and streaming box directly to the AVR to make that happen? —Andrew Last, via email

Q Can a TV’s built-in apps stream true 4K, or is it a lower resolution video format that the TV just upconverts to 4K? Also, would streaming via Wi-Fi instead of a hardwired Ethernet connection lower video resolution? —Cliff Parrish, via email

Q I have a Vizio TV, model number D48f-E0. The company’s specs say that it’s a “Full Array LED display.” It also has a “Backlight Control” in its picture settings menu that automatically dims or brightens the backlight during viewing. Is this feature the same thing as local dimming? I’m confused here — if backlight control and local dimming are separate features, what’s the difference between them? —James Paxton, via email

Q I have a Yamaha RX-A880 A/V receiver and a Polk Audio HTS-10 subwoofer. Can I connect the AVR's dual subwoofer outputs to the sub’s left/right Line In inputs instead of using its LFE input? Also, is there any benefit to connecting both the AVR’s subwoofer outputs to the HTS-10's LFE input using a Y-cable? —Power Bass / via email

Q My house has a well-lit living room where I watch TV. Are OLED sets bright enough to use in that space, or should I buy an LCD TV instead? —Paul G.

Q I have a modest home theater in my basement that I have been slowly upgrading over the last two decades. The only component I haven’t upgraded yet is my Polk Audio subwoofer since it was a pretty decent model when I purchased it 20 years ago. Would I benefit from upgrading to a new 12-inch sub? —Cal Rempel, via email

Q I made the decision to buy an Epson PowerLite Home Cinema 2045 3LCD projector about three years ago...I know I’ll need to change the bulb out at some point and would like to know how to tell when the lamp has dimmed to the point of needing replacement. I have no idea how many hours we’ve used it, or how to find out that information. —Scott Miller, via email

Q I own a Sony UBP-X800 Ultra HD Blu-ray player and want to know if all the 4K discs I buy provide high dynamic range (HDR). I’m also wondering if all 4K discs with HDR deliver it in both the HDR10 and Dolby Vision formats. —Steven Ganno, via email

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

Q I just bought Polk Audio Monitor 40 Series II speakers and want to know how to install them using bi-wiring. Do I connect two separate wires from the positive and negative outputs on the receiver and run them to the separate positive and negative input sets on the speaker? What benefits will that provide? —Kris Green, via email

Q I have a new Sony UBP-X1100ES Ultra HD Blu-ray player and Denon receiver. I know I can use a coaxial digital connection between the player and receiver for playback of regular CDs. Can I use the same connection to pass high-res audio formats like SACD and DVD-Audio to the receiver, or do I need an HDMI cable for that? —John Huxhold, Manchester, MO

Q I just finished listening to the new Giles Martin remaster of The Beatles’ Abbey Road via a 24-bit/96kHz stream from Qobuz. For the first few tracks I felt like I was listening to the original album, but on a much better stereo system. Then the bad news came when I got to the medley on “side two” starting with “You Never Give Me Your Money.” Instead of a seamless flow between songs, I heard distinct gaps between the tracks. It really ruined the experience. Why can’t streams of album tracks that are supposed to segue do so without annoying, and at times jarring, gaps in the sound? There are lots of iconic recordings with the same issue. —Thomas E. Moore, Fairfax, VA

Q I use an Oppo UDP-203 Ultra HD Blu-ray player and an Apple TV as sources, with the signals fed through a Marantz SR7011 AV receiver to an Epson Home Cinema 5050UB projector. From what I understand, the player, projector and receiver can all upconvert standard- and high-def signals to 4K. Which one should I let do the upconversion? —Michael Antoniello, via email
