Q My Denon AVR-S930H receiver supports pass-through of Dolby Vision high dynamic range. However, when I connect my Apple 4K TV to it, the Dolby Vision setting on the Apple box becomes unavailable and the signal changes to the HDR10 high dynamic range format.
I know the Denon passes Dolby Vision because when I connect my Oppo Ultra HD Blu-ray player to it, movies are displayed in the Dolby Vision format on my LG TV. I also know the Apple box isn’t the problem because Dolby Vision works when I connect it directly to the TV. Is there a setting in either the Denon receiver or Apple TV that I’m overlooking? —David A. Pilsner
Q My Windows-based Music Server (MediaMonkey) recently died and I want to replace it with one that supports music streaming services and will let me control playback with a tablet. I spent many hours ripping FLAC versions of my CD collection. Those files were stored on my PC’s hard drive, and I had them backed up offsite using iCloud. Here’s my question: If I buy a standalone music server like the Elac Discovery or Bluesound Vault 2, how can I restore access to my music collection that’s now sitting in the cloud? Also, can you backup data directly from the Elac or Bluesound servers to storage services like iCloud? —Jacques Simard
Q I’ve owned my Panasonic plasma TV for seven years but am now wondering about its life expectancy. Refresh rate, viewing angle, and, in particular, aspect ratio control are major concerns for my next TV. Can any of the latest TVs display a constant aspect ratio regardless of signal source? —Joe Nagy / via e-mail
Q Are movies on Blu-ray 3D disc delivered in 1080p/24 resolution — the same as regular Blu-ray? If not, what is the resolution for Blu-ray 3D, and does the format use a different, lower-quality form of video compression? —Gilles Gontrand
Q What receivers can power a Dolby Atmos 7.1.4 home theater? I plan to pair the receiver with a tower-based Definitive Technology BP9000 series speaker system and use that company’s A90 Atmos Enabled speaker modules for overhead effects. —Waymon French
Q I have a home theater system based around a Sony STR-DN1080 7.2-channel receiver and I’m on a quest to pick up new speakers to use for Dolby Atmos. What’s the best speaker match in the $1,000-to-$2,000 range? Also, how would I hook everything up to optimize the system for Atmos? —Ernest Walker / via e-mail
Q The connector on my in-wall HDMI cable broke off, and I have no way to replace it other than ripping into the wall. As a result, I’m wondering if the wireless HDMI products on the market are a noticeable downgrade from wired HDMI? —R.A. Oleson
Q I want to install a projector. Due to my room’s layout, screen width would be limited to 72 inches, and the projector would need to be mounted 16 feet away from it. I've messed with screen calculators for several projector brands and have concluded that I'm out of luck: a projector mounted at that distance would require a much larger screen. Do you know of any projectors that would work in my situation? —Stan Silverman
Q I have a Samsung HDTV and use the set’s analog minijack output to route an audio signal to my NAD integrated amplifier. Here’s my question: Would using an HDMI switcher/audio extractor that has HDMI inputs and HDMI and RCA-jack audio outputs increase sound quality? I have been told that using such a device would actually decrease audio performance. —James P. Landolt / via e-mail
Q I’ve ripped most of my CD collection to my computer using iTunes. At this point, I’d like to maybe get a portable media storage unit and transfer my iTunes library to it so I can play music through my AV receiver and Amazon Echo speakers. Is that a good idea? All suggestions are appreciated, but I am looking for an inexpensive solution. —John McGlynn / Boca Raton, FL
A There are a few ways to skin this cat. Here are some suggestions that won’t cost much money.
Q I have my Pioneer Elite SC-LX901 AV receiver connected to a 7.1 speaker system. When I press the SURR button on the remote, the receiver’s front-panel display shows all 7.1 speakers lit up and ready for action, but no sound comes out of the two Surround Back speakers. Do you have to watch a disc with a 7.1-channel soundtrack to get 7.1-channel sound, or can my receiver upscale a 5.1 soundtrack to a 7.1 format? The SC-LX901 is a Dolby Atmos-capable receiver, so I’d expect it to upscale 5.1 soundtracks for 7.1 output.—B. Hinson
Q
I currently use a receiver for watching movies in 5.1 surround and for listening to stereo music. I’d like to expand my system with a dedicated stereo preamplifier and amplifier for music playback but have realized that I would need to switch the cables of my main left/right speakers from the receiver to the amplifier every time I changed over from movies to music. Is there some type of switchbox that would enable such a setup? If so, is there an audiophile-grade version that wouldn’t negatively affect the sound? One more question: Would I be able use my subwoofer with both configurations? —Raphaël Rainville / via e-mail
Q I am looking to buy an AV receiver that can play music (mainly FLAC files) and movies streamed from a media server hosted on a NAS. Are there any new receivers that provide that feature? I was looking at a Pioneer VSX-832 Network receiver based on a recommendation from a local dealer, but discovered a note on Pioneer’s website saying that it’s not supported.—Gigi Mathew
Q I was planning to replace my 225Wpc Anthem Statement A2 amplifier with a 300Wpc McIntosh MC302 amp to improve my system. It was suggested that I would get more bang-for-the-buck by instead replacing my Integra DHC 80.3 surround preamp/processor with a new McIntosh MX122 surround preamp/processor. The reason given was that upgrading to a marginally more powerful amp wouldn’t result in a significant difference in my system, but a state-of-the-art processor would. Do you agree with that viewpoint? The speakers I am using are Definitive Technology Mythos STS Super Towers with a Mythos center channel and surrounds. — KJ King
Q I am building a dedicated 15 x 10 x 28-foot (WxHxD) home theater with two rows of seating and a bar for the third row. I plan to buy new speakers and am interested in the advantages, if any, of line-source over regular point-source designs. I’ve heard that line-source speakers create a larger stereo sweet spot. Is that the case? —Lorne Charles / via e-mail
