Q I just purchased a Samsung Ultra HDTV and plan to buy an Ultra HD Blu-ray player. My current AV receiver is four years old. Is there any way I can get a 4K picture and Dolby TrueHD/DTS-HD Master Audio sound without having to buy a new receiver? —Michael Errico / via email
Q I own an Epson 5040UB projector that is high dynamic range-compatible and has “4K Enhancement Technology.” But it’s my understanding that projectors are unable to deliver all the benefits of HDR. If that’s true, is it worth it for me to upgrade to an Ultra HD Blu-ray player to use with my 5040UB? —Harry Torres
Q The HDMI cables I’ve been using with my current TV are now eight years old. I plan to buy a new OLED TV. Will I need new HDMI cables for it? —Jim Stafford / via email
Q I own a 720p-resolution Pioneer plasma TV. Every time I use my old plasma—now relegated to my photography studio after being replaced with a Full HD LCD model in the living room—I am blown away by the rich blacks and crisp color. It just looks better than LCD. With the arrival of 4K and HDR (finally, TV tech that can match the color gamut of the computer monitors I use for photography), I’m thinking it may be time for another upgrade. Are there any HDR-compatible UHDTVs that perform well enough to finally end my love affair with my plasma? — Ed Nazarko / via email
Q I recently watched a video labeled “4K” using my Panasonic Ultra HDTV’s built-in YouTube app. When I paused the video, I noticed an icon next to the playback controls that said "Stats for Nerds." Clicking on the icon, I discovered that, while the video was originally shot in 4K, it wasn’t playing back at that resolution. Why does YouTube claim to have 4K content when their system doesn’t play the videos in 4K? —Wayne Mathews, Stone Mountain, GA
Q After reading soundbar reviews in Sound & Vision, one thing seems clear: to get the best sound, you need to combine a soundbar with a subwoofer. My problem is that I will soon be moving from a house to an apartment. As I’m sure you’re aware, the tenant with a subwoofer in an apartment building is usually the least favorite neighbor.
My current 5.1 setup includes Definitive Technology ProMonitor 800s, a ProCenter 1000 and ProSub 1000. Everything is hooked up to a Marantz 7701 preamp/processor and matching amp. Do you have any suggestions for replacing my system with a standalone soundbar that won't compromise on bass? I would ideally like to continue using the Marantz amp and preamp. —Brian Morgan
Q My Sony Blu-ray player can play DTS-HD Master Audio soundtracks with up to 192-kilohertz/24-bit resolution. However, my receiver’s specified bandwidth is 20 Hz to 20 kHz, and my Polk 330T speakers only cover a frequency range of 33 Hz to 25 kHz. Am I losing sound quality because the receiver and the speakers aren’t spec’d to handle frequencies up to 192 kHz? — Javier Feliciano / via email
Q I know that subwoofers are recommended for use with small bookshelf or satellite speakers, but are they also needed with floorstanding tower speakers such as the GoldenEar Technology Tritons? — Frank Hendricksen / via email
Q I am planning to buy a 2.1-channel soundbar and have noticed many are only capable of decoding standard Dolby Digital soundtracks. However, one 2.1-channel model I looked at, Sony's HT-NT5, supports Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD Master Audio, DTS-HD High Resolution, DTS ES, and DTS 96/24. What is the advantage of a 2.1 channel soundbar being able to decode multiple multichannel audio formats? —Joe Pop
Q I’m looking to buy a 65-inch LG OLED Ultra HDTV to replace my Pioneer Kuro plasma, which is now 9 years old. Here’s my question: Should I wait until TVs and other components all have HDMI 2.1 connections, or should I just buy current models? Also, can products with HDMI 2.0a connections be updated to HDMI 2.1? —Alan McClure
Q Both of my universal disc players allow me to adjust for speaker size and distance in the audio setup menu. The receivers I’m using them with provide the same functionality, but one has manual setup (Arcam Diva AVR-350) and the other has Audyssey auto setup (Marantz SR7010). Which component should I use in each system to configure speaker size and distance: the player or the receiver? —Jan Nieuweboer / via email
Q It looks like the high data rate (up to 48Gbps) of the forthcoming HDMI 2.1 standard will create headaches for the consumer electronics industry, especially the cable manufacturers. Here’s my question: Why does decompression of video data happen in the disc player or streaming box instead of the TV? If the situation were reversed, then there would be no need for new, 48G HDMI cables. —Dave Ings / Toronto, Canada
Q I have a Denon AVR-X7200WA A/V receiver and a 9.2-channel speaker system. I recently
bought an additional pair of height speakers and a Marantz five-channel amp to expand the system to 11.1 channels. How should I go about connecting the Marantz amp? —Dipin Patel / via email
Q I love the idea of converting vinyl (especially my Mobile Fidelity Sound Lab LPs) to a hi-res digital audio format and Sony’s PS-HX500 USB Turntable seems like just the ticket. However, I already own a high-end turntable and don’t want to buy a second one. Are there any devices I can connect to my turntable to make hi-res transfers of my record collection? Thanks —Rob Lowe
