A I’m using a Yamaha AX-497 integrated amplifier to power a pair of Elac speakers with a nominal 4-ohm impedance. I also have a Yamaha YST-SW315 subwoofer I’d like to use in my system. Here’s my question: If the speakers are wired directly to the amp as speaker pair A, and the powered subwoofer is connected as speaker pair B, can I power both simultaneously without damaging the amplifier? (The amplifier’s manual warns against connecting more than one pair of 4-ohm speakers.) For convenience reasons, I would rather not wire the main speakers through the subwoofer. —V.A.

Q There’s been much discussion about MQA technology and its capabilities, but the only products that support MQA are a handful of DACs and stereo amps.

When can we expect to see MQA in mainstream AVRs such as those from Marantz, Yamaha, Denon, Pioneer, and Onkyo? For me, there’s no point in upgrading to a new receiver now if MQA decoding can’t at least be added via a firmware update. —Jacek G.

A I own an Integra DTR-40.6 AV receiver that is capable of playing Hi-Resolution Audio (HRA). Here’s what I want to know: If I were to upgrade my Pandora or Spotify account to stream HRA, would I be able to listen to it using the Pandora or Spotify app built into the receiver? My internet service plan is 50-Mbps FIOS, and I have the receiver connected to my router with an Ethernet cable. &Tony Held / via e-mail

Q I own an Audio-Technica AT-LP120-USB turntable that I’ve modded. I’ve also purchased a Cambridge Audio CP1 phono preamp to connect the Audio-Technica to my Denon AVR-X6200W receiver. Can you help me understand how to hook the CP1 up to the Denon? I’ve tried many options but still fail to get sound. The turntable plays when plugged into another amp so I know it’s working correctly —Rodger Benson

Q I’m interested in reconfiguring my speaker setup for object-based audio. Should I leave the surround back speakers in place, or set them up as height speakers? —Michael Welters

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 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 Are any of the new Ultra HDTVs coming out 3D-compatible? I don’t want my 3D Blu-ray disc collection to become an unusable relic. —Don Fowler

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
