Q I’ve been bouncing around the idea of upgrading my current gear and going digital because my wife and I want the convenience of being able to cue up any piece of music using our iPhones.

Q I own a Pioneer Elite VSX-49TXi receiver that I’m using in a bedroom system because it lacks HDMI connections. My plan is to upgrade the Onkyo receiver in my theater room with a Marantz pre-pro plus a power amp. Here’s my question: Could I use the Pioneer receiver purely as a power amp connected to the Marantz pre-pro? —Rick Jennings, Hollister, CA

Q I’m shopping for an outdoor speaker to use on my back patio and was leaning toward Sonos. Here are my questions: Can I stream audio to Sonos speakers via Bluetooth from my iPhone? Also, are Sonos speakers able to both play tracks from my computer’s iTunes library and stream them from Apple Music? —Jim Flynn

Q Will I damage a stereo amplifier by using it to amplify only one channel—in this case, my system’s center speaker?—Richard Regan

Q I have been reading A/V magazines for years, as well as conducting my own research, and am still a little confused about how to select the right amplifier to use with MartinLogan electrostatic speakers. The literature I’ve read clearly indicates that the ohm rating of a receiver is just as important, or more so, than its wattage per channel when considering an A/V receiver to pair with speakers. Does the ohm rating of MartinLogan electrostatic speakers make them incompatible with typical AVRs?

Q Help! Perhaps it's the case that I don't understand the Dolby Atmos specifications, but I get the impression that if I build an Atmos system with four height channels, I will also need to purchase an expensive receiver.

I want the unit I buy to handle both two-channel analog music and big-budget films with multichannel soundtracks. Is there such thing as a receiver that can process Dolby Atmos soundtracks for a 5.1.4-channel speaker layout but also let me use a high-end stereo amp to power the front channels? —Joshua Gonzalez, Houston, TX

Q Are different wireless speakers compatible with each other? I own several Sonos speakers, but have recently noticed more top-line speaker makers (e.g., Definitive Technology, Polk) starting to distribute their own. As I continue expanding my wireless hook-ups, I’m wondering if I'm locked-in to using just Sonos? —Stephen Romanelli

Q I have a 7.1-channel surround system with four dipole surround speakers. My plan is to move the back surround speakers to the ceiling in my home theater and use them for down-firing height speakers in a Dolby Atmos 5.1.2 setup.  The room is 12 x 20 feet with a flat, 8-foot-high ceiling. Will I get a good Atmos experience with this setup? How will it work for DTS:X? —Dan Spaughs

A Here’s a question that has probably been asked and answered a thousand times. I plan to upgrade my system from a 7.1-channel to a 7.1.4 Dolby Atmos configuration. Should I replace my current dipole surround speakers with direct-radiating speakers? Also, which 11.2-channel AV receivers should I consider buying? —Dave Brown / via e-mail
