Q I’m trying to choose between new AV receivers from Sony, Denon, and Yamaha. The Sony is the frontrunner, but I am hesitant to pull the trigger because it’s not HDCP 2.2 compliant. If I connect an HTPC to this AVR, will I have problems in the future playing Ultra HD movies? How about satellite? Will I have the same problem if I eventually upgrade to an Ultra HD-capable satellite receiver?—Sam Shirzadegan

Q I’m preparing to make a big, across-the-board system upgrade, much like I did several years back when HDMI 1.3 became standard for most devices. Will I need to replace my 5-year-old HDMI cables with new, higher speed ones to accommodate 4K video and HDMI 2.0/HDPC 2.2? —Mark Johnson

Q I have a question about playing 7.1 DTS-HD Master Audio soundtracks on a 5.1 speaker system. I understand that my receiver will mix the back rear channels into the surround channels, but will that cause the playback to lose the lossless quality DTS-HD Master Audio was designed to deliver? —Len Shift

Q I have plans to buy a new LG 65EF9500 OLED TV. Here’s my question: How long a break-in period would you recommend before having it professionally calibrated? I used my current Panasonic plasma for about 100 hours before having it calibrated.  Also, can any ISF-certified technician handle an OLED TV, or does it require special training? —John Violette

A It’s recommended that you treat an OLED TV the same as you would a plasma for the first 100 hours of use, being careful not to leave fixed images like electronic program guides or paused video game frames onscreen for an extended amount of time. This will be especially important when viewing high dynamic range (HDR) content with the 65EF9500. LG even warns about the potential for burn-in in the EF9500’s manual and recommends steps you can take to prevent it, though any image retention you experience in most situations should only be temporary.

Q Do all speaker wires running to matched sets of speakers need to be the same length? I’m using 12 AWG wire to connect my AV receiver to speakers with an impedance of 6 ohms. My plan was to use 3-foot runs to my right and center speakers, a 10-foot run to the left speaker, and 26-foot and 36-foot runs, respectively, to the left and right surrounds. Will this create a problem? —Dan Donna / via e-mail

Q I want a great-sounding home theater system (preferably wireless) that won’t break the bank. I’m interested in the Sonos system (PLAYBAR, PLAY:1 rear speakers, and SUB). The only downside is that Sonos doesn’t support AirPlay—a deal-breaker for me since much of my music is on Apple devices (MacBook, iPad, and iPhone). Someone told me I don’t really need AirPlay to play my iTunes library through Sonos. Is that true?—Paul Fox

Q I’m curious to know if there’s any criteria for home theater component selection based on room dimensions. I want to focus my search on equipment that’s an appropriate match for my space. —Bill King / via e-mail

With more and more music and video being stored by consumers on external hard-disks, those disks have themselves become valuable commodities. You’d think someone who took time to rip an entire CD and/or DVD collection, or downloaded a boatload of high-res albums from HDtracks, would make the additional step to secure their data by backing it up. But in many situations that isn’t the case.

Q I wish to place center-channel speakers above and below my projection screen. I know the distance from the two speakers to the seating position at ear level will not be the same, and I would like to know how to calibrate or compensate for this difference. I have a 5.1 surround setup with an Oppo BDP-105 Blu-ray player, a six-channel amp, and a powered sub. I am patient enough to do the onscreen setup from the Oppo, but I’m at a loss over the dual center speaker issue. —Dale Kay / via e-mail
