Q I plan to purchase a new AV receiver and a set of 5.1 speakers. What strategy will deliver a better all-around experience: spending more on the speakers or on the receiver? Should I splurge on speakers, with the idea that my receiver can be upgraded in a few years, or vice-versa? Simon Bolster / via e-mail

Q The 4k content I see on UHDTVs in stores looks awesome. But when I ask the salesperson to flip the feed to regular HD (from Direct TV), the picture doesn’t look nearly as good. It looks worse, in fact, than the same content shown on the standard HDTVs, and certainly worse than on my 10 year-old Sony SXRD.  My question is, if I buy a new UHDTV, how can I make the picture look as good as what I’m used to seeing on my Sony? There isn’t much 4K content yet, so what I’d mainly be watching is regular HD.—Ben Soave

Q Will I damage a stereo amplifier by using it to amplify only one channel—in this case, my system’s center speaker?—Richard Regan

THE VERDICT
Sharp’s 4K THX Certified UHDTV gets many things right but some key things wrong.

The only TV-tech buzzword with any legs to it in 2014 was 4K, aka Ultra HDTV. So a TV manufacturer without new 4K-resolution product had better start thinking about packing it in. Sharp previewed a pair of UD27 series Ultra HDTVs last June, and the company finally squeezed out those models just in time for the holiday shopping season. What do the new 60- and 70-inch Sharps have to recommend them over other, similarly priced offerings? Let’s check things out.

Q I just signed up for Tidal music streaming and want to make sure I am getting the best sound quality from that service. My laptop is connected to my router with an Ethernet cable and then to my Onkyo pre/pro via an HDMI cable. I have the Tidal app’s settings set to HiFi.

My question is, as music streams from Tidal, does it pass through the laptop’s sound card first and then to the HDMI cable, or straight from the HDMI cable to the Onkyo pre/pro? I don’t know what sound card is equipped with the computer, and want to make sure that if streamed music does pass through, that the card isn’t detracting from the sound quality. —Andre Spits / Atlanta,GA

Q I have owned receivers from Onkyo, Pioneer and Yamaha. With each one, the sound always seemed muddy after I used the auto-calibration function for speaker setup. In my experience, I get much better sound when setting all speaker crossovers to 200 Hz, or the highest available setting. Expert opinions I’ve read on the subject say this is wrong, though I’ve adjusted two friends’ systems in this way and they agree with me that the sound is better. Am I correct? —David Bone

Q Why can’t audio devices be daisy-chained via Bluetooth? I have a NAD Viso 1 speaker dock and a NAD 3020 integrated amp, both with Bluetooth. The units are located in different rooms. Why can’t I send the same signal from my iPhone to both units at the same time?—J. Alan Greer

Q I have a fairly large collection of CDs, all of which have been ripped to lossless WMA format. I’ve come across plenty of discussion of DACs while researching music servers, but I’m confused about why I would need one since I can already listen to digital music files, either through my computer speakers or headphones. Doesn’t that mean what I’m hearing is already in analog form? If so, what need is there to convert it to anything else? —Bill Begg / via e-mail
