Q Sony recently announced a firmware update that adds Dolby Vision support for my TV, the XBR-65Z9D. Here’s my question: Will my Pioneer Elite SC-LX901 receiver be able to pass signals from Dolby Vision discs played on Ultra HD Blu-ray players that support Dolby Vision? The SC-LX901 is equipped with HDMI version 2.0a connections, so I’m assuming it should have no problem. —Cesar Sanchez

Q I recently bought a Marantz 7702mkII preamp-processor and am wondering about the best options for streaming high-res FLAC and other lossless files from my computer. The Marantz wants me to use my Windows Media Player library when setting up a media server connection. However, it’s my understanding that WMP can’t play FLAC files without additional transcoding, and even then it can’t handle files with 24bit/192kHz resolution. Do you have any recommendations for getting the best-quality playback from my high-res audio downloads? —Trey M. Turner

Q I’m using a Marantz SR5005 AV receiver rated at 100 watts per channel to power a 7.1 speaker system. My surrounds sound like they’re getting enough power, but I’d like to add three external 200-watt monoblock amps to increase output to the front left, center, and right channels. Here’s my question: Will the receiver’s Audyssey MultEQ automated setup calibrate the system in a way that accommodates the added power? In other words, will I still get full power from the front three channels if I use external amps and Audyssey MultEQ? —Todd Hunt / via email

Q I’m ready to upgrade my surround sound system to a 5.1.4 Dolby Atmos configuration. My current 5.1 system uses GoldenEar Technology speakers, which I want to keep. Here’s my problem: I have no way to run wires through the ceiling to mount in-ceiling speakers, and I don’t want to deal with the unsightly wires that an on-ceiling speaker installation would require. Here’s my question: Are there any wireless speakers I could use for my Atmos upgrade? —Michael Henn

Q Do you know of a good solution for streaming audio from a Windows PC to B&W P7 wireless headphones using Bluetooth? Is there some kind of USB adapter? —Robert Prinz

Q Should I use the quartz lock feature on my Audio-Technica AT-LP120 turntable? I don't see or hear any difference when I press the quartz lock button. Same thing when I press the +10 /+20 pitch control button. FYI, I usually play records with the +10 pitch option selected. —Josh Rosenthal

Q I'm slow to bite on buying an Ultra HDTV because I’m waiting to see which high dynamic range format will stick. If I buy an HDR10-only set and Dolby Vision wins, can support for that format be added through a future software update? —Ray Blackburn
