Q I’m still using my first system that I bought in the late 1960s. Time for an upgrade! I’ve seen speakers with four drivers and speakers that use only one driver. Can you explain the advantages of one design over the other? For example, is it possible for a tower speaker with a single driver to sound better than one with three or more drivers? —Michael Oleson, Fort Worth, TX

Q I have a Sony XR-90J TV that supports 4K/HDR and Dolby Atmos. Here’s my question: For a fully Atmos-compatible system, do I also need a receiver, Ultra HD Blu-ray player, and HDMI cables specifically designed to support Atmos? —Rayfield Coston, via email

Q I own a pair of Edifier S2000 Pro Bluetooth bookshelf speakers. I love listening to music through these, but often want to hear more bass and this model doesn’t have a subwoofer output. What are your suggestions for getting better bass from a Bluetooth wireless speaker system? —Jeff Crunkleton, via email

Q I want to get the highest possible audio quality from my home theater system when using the streaming apps on my new Samsung QN90A Neo QLED 4K smart TV. Is the TV’s eARC port compatible with my Denon receiver’s ARC port? By compatible, I mean will the Denon “understand” the Dolby Digital Plus bitstream coming from the apps and just ignore any Atmos metadata? —George Perkins / Madison, WI

Q I own an NAD T 787 A/V receiver that only supports regular HD video pass-through and Dolby True HD/DTS-HD Master Audio processing. This receiver features NAD’s MDC (Modular Design Construction) for hardware upgrades. NAD offers an audio module with Dolby Atmos support, along with outputs for two sets of height speakers. If I stick with my current 5.1 speaker setup, would the Atmos module upgrade improve sound quality? Or will my receiver simply downmix the Atmos soundtracks to 5.1/7.1 surround with no audible improvement? —Phil Tomaskovic, via email

Q I’m in the process of rebuilding my home theater with a 4K projector and flat-panel TV. Here’s my question: What kind of HDMI extenders can I use to pass a video signal with Dolby Vision high dynamic range (HDR) from my receiver to both screens? I’m completely at a loss here. —F. Hudson Miller, Hollywood, CA

Q I read your response to a reader who asked about using dipolar speakers as surrounds in an Atmos system. You recommended “losing any side-mounted dipole surround speakers in the system and replacing them with properly positioned direct-radiating models.” Does that same advice hold for bipolar surrounds? —Darryl Brooks, via email

Q I tried to watch Cruella on Disney+ and was shocked by the poor video quality presented by my Roku streaming device. I was able to make the movie watchable by changing the color mode and lamp settings on my Epson HC 4010 projector, but still wonder exactly what happened. Have you noticed that some movies look notably darker than others? If so, does it have anything to do with high dynamic range (HDR)? —Gary Eickmeier, via email

Q I have tried streaming Amazon Music HD to my Marantz SR7015 receiver over Bluetooth from my iPad using the receiver’s HEOS app. The app shows resolutions all the way up to 24 bit/192kHz — something I didn’t think was possible with Bluetooth! Will I get the same resolutions if I make a hardwired connection from iPad to AVR using an AudioQuest DragonFly Red USB DAC? —Paul Giovino, via email

Q Way back when surround sound at home was the new big thing, installing dipole surround speakers at either side of the main listening position was recommended. Are dipoles still the optimal surround speaker choice now that technology has transitioned to object-based audio formats like Dolby Atmos? —Steve Benoff, Beaumont, CA

Q I own a Marantz SR6013 A/V receiver and use it for both video switching and audio amplification. For video, I mostly watch Ultra HD Blu-ray discs. For music, I mostly stream from the Tidal service using the Marantz receiver’s built-in HEOS app. I would like to buy an external digital-to-analog converter (DAC) that supports MQA but am confused about the connections and the control app. After checking out my Marantz AVR’s back panel, I see two coaxial and optical digital inputs, but no digital outputs to connect the DAC, so maybe using an external DAC with the AVR is not possible. Am I missing something? —Rod McClaskey, via email

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 Do the preamp outputs on A/V receivers work as well as those on a standalone preamp-processor? What functionality does one lose when using pre-outs on a receiver? —Ravinder Dhawan, Watchung, NJ
