Q My partner and I want to get set up for high-resolution audio and are hoping to use the Tidal service for better-than-CD-quality streaming. We have a Sherwood stereo integrated amplifier from the 1980s, along with big, beautiful, fantastic-sounding speakers and we don’t want to give those up. I’ve tried researching the huge range of available tech options but just don’t know how to make it work. We use Android devices and own a Fosi Audio DAC-Q4 [digital-to-analog converter/headphone amp]. We also have a spare computer that can be used to run Tidal. —Victoria Baker, via email

Q What’s the best way to connect a subwoofer used mainly for music listening? I’ve been trying both the stereo RCA and mono LFE input connections on my Klipsch R 120SW subwoofer, but am not sure which works best, and also where I should set the low-pass/LFE filter on my Onkyo TX-NR717 receiver. My front speakers are Klipsch R-28F towers. I would appreciate any recommendations on crossover settings for the receiver and the subwoofer itself. —Ken Zarubi, via email

Q I am planning an upgrade to Panasonic DP-UB9000 Ultra HD Blu-ray player. Can I can connect the player’s 7.1 analog output to my Yamaha AVR’s multichannel input (like I currently do with my Oppo player) and hear Atmos/DTS:X? —Rick Poage, Fairfax, VA

Q My LG V30 smartphone has a high-performance Quad-DAC audio system capable of decoding hi-res files encoded with MQA. I want to use the LG phone as a source to stream Masters-quality music from Tidal via Bluetooth (aptX HD) to my new NAD integrated amplifier. Will this work for MQA, or do I need an external digital-to-analog converter to “unfold” the MQA-encoded files? —Joel Johnson, via email

Q I ordered an Epson 5050UB LCD projector with 10 lens-shift memory settings and am looking for a projection screen. Information on one screen manufacturer’s website says you lose 25 percent (over 2,000,000 pixels) and up to and 25-30% of brightness when using a lens-shift memory setting to zoom images to fill a 2.40:1 “scope” screen…and when a projector blacks out pixels during this process, it absorbs the light energy, creating excess heat. Is this information accurate? Also, should I instead consider using an anamorphic lens with the projector? —Douglas Bien, via email

Q I have over 9,000 songs on a hard drive hooked to my computer. When I listen, I stream it over my home network to a Samsung TV connected to a Denon receiver. The audio is fine but the visual effect of browsing through folders on a 70-inch screen leaves much to be desired. Is there an inexpensive way to browse and play your stored digital music library in a home theater using a visual interface like Microsoft Groove Music? —Jay Sklaroff, via email

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
