Q I’m wondering about the best setup to stream music from my computer. I currently use an Apple TV connected to an Onkyo receiver to stream Apple Lossless files from my Mac via AirPlay. Is there a better way? Should I add an outboard DAC or switch to a different network streaming device? —Rafael Cremonese / via e-mail

Q I’m in the market to buy a new receiver. The speakers I’m using are powered models that I plug directly into the back of the receiver. My question: Will it hurt or decrease the life of the speakers if I instead plug them into a regular AC outlet on my wall? New receivers I’ve checked out with features that I like do not provide AC outlets. —Bill Major / via email

You won't be hurting or decreasing the life of your powered speakers by plugging them into a regular wall AC outlet. Instead, you’ll be helping them.

Q I’m looking to buy a new receiver and was checking out Yamaha’s RX-A1030. A problem with that unit, however, is that it doesn’t appear to route signals from an optical digital input to its second-zone output—a feature that I require. (Other than that, the RX-A1030 has everything I need.) Is there another option on the market that can do this? Researching receiver specs is very tiring because specific info is hard to find. —Pete via email

Q: I have a Yamaha 7.1-channel AV receiver in my system that’s set up to power a 5.1 speaker system. Very seldom do I hear sound coming out of my surround speakers when watching movies on Blu-ray, though I do occasionally hear sounds like thunder. I have even boosted the output of the surround channels relative to the fronts, and it doesn’t make a difference. What’s going on?—Chuck Schumm / via e-mail

Q I want to get better sound when watching movies on my new Panasonic ZT60 plasma TV. (I stream a lot of Netflix and Vudu via the Panasonic’s built-in apps.) To that end, I recently bought a small stereo setup: an NAD C326BEE integrated amp, a Musical Fidelity V90 DAC, and a pair of Monitor Audio Apex 10 speakers. The only way to connect the TV to my audio system is by using an optical digital output from the Panasonic to the DAC, which then connects to one of the NAD’s stereo RCA inputs. Here’s the problem I’ve been having: When I watch Netflix or Vudu, I hear nothing but static noise coming from the speakers, though the sound is fine when I watch DirecTV (I have my satellite receiver connected directly to the TV via HDMI). This noise went away when I switched from 5.1 to 2.0 audio in Netflix, but I don’t get the same option for Vudu. I’m kinda stumped at this point. Shouldn’t the Musical Fidelity DAC automatically dumb down 5.1 signals to stereo? Is there another possible configuration that can solve my problem? —Gilbert Solis / via e-mail

Q I thought that plasma TVs don’t suffer from motion blur, but I definitely see it when watching with my new Panasonic TC-P60ST60 plasma. Is there some setting I have configured incorrectly, or was I wrong in thinking that plasma tech is free from motion blur? —Bob Shedlock / Strongsville, Ohio

Q Most movies on DVD and Blu-ray default to 5.1 surround sound, but most concert videos default to 2.0 stereo, and the viewer has to manually select 5.1 surround when playing the disc. What’s the reason for this? —John Kellam / Tucson, AZ

Q My system consists of Aerial speakers, a Rotel 5 x 100 watt amp, a Marantz AV-7701 pre/pro and a Panasonic Blu-ray player. All my music is stored on a Mac computer and streamed to an Apple TV which is connected by an optical cable to the processor. The sound with movies is fine, but digital music lacks detail and has no WOW to it. My car’s Krell audio system sounds far superior in comparison. All music files on my Mac are in 16-bit WAV format. What am I missing? —Roland Bertha / South Florida

Q I’ve owned two high-end plasma HDTVs, but recently purchased a new LCD UHDTV (Samsung HU8550). Watching Blu-rays on the new set using an Oppo player and Onkyo NR929 AVR, I am seeing something disconcerting that I never noticed before with the plasmas: Whenever there’s a fade-to-black transition between movie scenes, the screen abruptly goes black for about 1-2 seconds in the middle of the transition/edit. Is this sort of thing typical for LED-backlit LCD TVs? It ruins the viewing experience for me. —Richard Rife via email

Q I have a Denon AVR-4310CI A/V receiver. Although I have speakers connected for all seven main channels, I have never heard a movie with 7.1-channel sound. My sources are Blu-ray and Verizon Fios HD. What do you think is going on? —Mister Phillip
