The difference between regular and high-definition video is something that most folks will immediately recognize when they see it. But what about high-resolution audio? Unlike HDTV, which caught on fairly quickly and enjoyed a broad base of support from program providers and hardware manufacturers, hi-res audio or HRA, (now an industry-sanctioned term) has struggled to move out of its audiophile niche since downloadable content first came online back in 2008.

Competition in the computer business has heated up over the past few years, with companies slashing prices to the bone in order to move product. You can now get a PC with a speedy processor and huge hard drive for only $399, and they'll undoubtedly cost less than that by this time next year. What's a forward-thinking computer company to do?

The ongoing iPodification of audio has generated a huge number of products designed to sync up with, amplify, and otherwise expand the possibilities of Apple's ubiquitous player. Many first-wave iPod add-ons got the cosmetic part right (white plastic cabinet? check!) but failed to impress when it came to music reproduction.

Need a good reason to buy a projector? How about this: Of all the video-display types, projectors provide the biggest image for your buck. Rear-projection TVs, which were once available in screen sizes up to 92 inches, used to be an even more affordable big-screen option, but the last manufacturer with a stake in rear-projector manufacturing, Mitsubishi, recently closed up on that biz.

One of the best demos I took in at CES was provided by French tech company Giroptic, a participant in the cutting-edge Tech West expo at the Sands. Part of it had to do with the quality of the seamless 360-degree HD video captured by the company’s Go Pro-style compact camera. But a bigger part had to do with the fact that the footage was being displayed on the Oculus Rift—my first experience with that storied, soon-to-come VR headset.

Q I own Paradigm Monitor 11 speakers and an 80-watt powered subwoofer. The speakers are set up in my living room 6 feet out from a sliding glass door. What type of acoustic treatment product should I put up behind the speakers to improve their sound? Should it be foam or something more solid? —Jon Cotton / via e-mail

Say what you want about soundbars, but the category counts as one of the more active areas of speaker design. Sure, many products pumped out over the last few years are low-end ones designed to be sold as accessories for flat-panel TVs. But plenty of serious speaker companies have also gotten into the game, and the performance of the resulting products, while not yet at a level to make audiophiles toss out their tower speakers en masse, has proven more than sufficient for casual home theater use, as well as for background music listening.

As an A/V connection standard, HDMI has its downsides: limited cable length, glitches, slow switching, and version upgrades that make new gear incompatible with old stuff — the list goes on. But a major upside is that one interconnect can handle the jobs previously carried out by a thick wad of cables. In its most current version, HDMI 1.4, a single link will convey high-def video/multichannel audio, link devices to a local network (HDMI Ethernet Channel), and route audio signals from a TV back out to an A/V receiver  (Audio Return Channel). Sweet!

But any TV making the hook-up also needs to be plugged into a power socket. That means an additional wire, plus the logistical problem of locating a TV near an AC outlet — or, for a wall-mounted installation, of embedding one within the wall (a task that generally requires the services of an electrician). Wouldn’t it be great if HDMI also carried power?

HDMI can’t. But HDBaseT can.
