A few weeks ago, Home Theater editor Rob Sabin posted an editorial about the growing number of Internet service providers that throttle the bandwidth of any subscriber who sends and receives more than a specified amount of data. Typically, the limit is 150 or 250GB per month, which seems like a lot—until you stream a few high-def movies and perform cloud-based backup of your entire hard drive, after which you find yourself slogging along at dial-up speeds or paying much more for your Internet access. With some ISPs that are also content providers, such as telecom and cable companies, accessing their content does not count toward the limit, but venturing outside their ecosystem does.

Does your ISP engage in any of these pernicious practices? If so, I'd love to know what your limit is and what happens when you exceed it. I encourage you to leave a comment with these details.

CES may be the biggest consumer-electronics trade show of the year, but CEDIA often includes more important product announcements for home theater specifically, and this year was certainly no exception. We saw and heard lots of super-cool toys in Indianapolis earlier this month, as we reported in our extensive coverage.

Now it's your turn to tell us what you found most exciting from CEDIA, whether you were there in person or followed our posts from the show. For this poll, I've listed a few of our favorite items, but of course, there was far more to pique the interest of any home-theater buff, so if your fave isn't here, click on "Other" and let us know what it is in the comments.

The appearance of 4K home-theater projectors from Sony (4096x2160, seen above) and JVC (which is really more of a "pseudo-4K" that upscales 1080p to 3840x2160) has sparked increased interest in super-high resolution for consumers, especially since 4K seemed like a far-off dream until now. But many argue that the benefits of higher resolution are not visible on any screen size intended for home use. In fact, most people can't see the pixel structure of a 2K digital-cinema projector on a much larger commercial screen when sitting at a normal viewing distance, so how could they perceive the increased resolution of 4K on a smaller home screen?

Then there's the issue of 4K content, which I believe won't be available for distribution to the home for quite some time, if ever. Yes, we might see 4K-capable media in the next year or two—for example, BDXL optical discs and RedRay servers—but the studios give relatively few movies the full 4K treatment, and I bet those same studios will be loath to release movies for the home market at 4K. Until they do, owners of 4K displays will be limited to upscaled 1080p, which isn't all that much sharper than the original and carries the risk of scaling artifacts.

So I wonder how important 4K really is in the home? What do you think?

Last week in his Audiophiliac blog, Steve Guttenberg mused about how audio measurements relate to sound quality. He concluded that objective measurements do not correlate with subjective evaluations, primarily because well-defined test tones have little to do with real musical signals.

Here at HomeTheater.com, we've certainly observed that poor measurements do not necessarily mean poor subjective performance, and that good measurements do not necessarily reflect good performance. On the other hand, in our experience, measurements sometimes support—and even explain—a reviewer's subjective observations, which are always conducted before the measurements.

Do you think that objective audio measurements using test tones correlate with subjective sound quality playing music? If so, is it a strong or weak correlation? In the comments, I'd love to know how much weight you give the measurements found in our reviews compared with the reviewer's subjective assessment.

Yesterday, I helped Tom Norton unpack and set up a 60-inch Sharp Elite PRO-60X5FD LED-backlit LCD TV (shown on the right above) that he will review over the next couple of weeks. (Interestingly, the name Sharp appeared nowhere on the box, only Elite.) Even before setting the basic picture controls—but after selecting the Elite Pure picture mode and Low color temperature—the image looked remarkable, with deep blacks, bright whites, and rich colors. Also, the Sharp is sitting next to Tom's 60-inch Pioneer Elite PRO-141FD plasma (on the left above), so he will be able to do direct side-by-side comparisons to see if Sharp has managed to wrest the flat-panel crown from the Kuro.

In addition to exceptional picture quality, both TVs have something else in common—a very hefty price tag. The PRO-60X5FD lists for $6000, while the 70-inch version is a whopping $8500. (The 60-inch PRO-141FD was $7000 in 2009.) In my opinion, such high prices lead to the demise of the Kuro, because a best-possible-performance, cost-no-object flat panel is unsustainable in today's—or even yesteryear's—economic climate. So I'm concerned that the new Sharp Elite TVs will suffer the same fate as the Kuro.

Do you think ultra-performance, ultra-expensive flat panels can succeed in today's marketplace? Or are they simply too expensive to manufacture and sell in quantities large enough to make business sense?

Despite their high efficiency and low power consumption and heat generation, class-D amplifiers have long been relegated to second-class status by much of the audio community, appearing mostly in low-cost, low-performance audio products. (One notable exception is powered subwoofers, which require amplification only in a limited frequency range.) Lately, however, full-range class-D amps have gained more respect—for example, Pioneer has been using this technology in several generations of its Elite AVRs, including the 2011 SC-55 and flagship SC-57 reviewed exclusively on HomeTheater.com.

Reviewer and long-time class-D detractor Michael Fremer was finally won over by the new Class D3 amp used in the SC-57 (shown above), but many audiophiles still scoff at this technology, preferring the sound of purely analog class-AB designs. What's your take? Have class-D amps finally achieved a performance level commensurate with class-AB?

These days, high-def TV shows are available from three basic platforms—broadcast (including cable, satellite, and over-the-air), online streaming, and Blu-ray. The order in which I've listed them here also corresponds to a current show's availability—first, it's broadcast, which is quickly followed by its appearance on one or more streaming sites, and finally Blu-ray months later (if ever).

In terms of quality, streaming is clearly at the low end—even so-called "high-def" streaming—with its high data compression and often 2-channel audio. Next up the food chain is broadcast at 1080i or 720p with lossy Dolby Digital 5.1 audio (and the inevitable commercials). At the top of the heap is Blu-ray at 1080p with lossless 5.1 audio.

All of which begs the question—what's more important to you, availability or quality? Do you tend to choose broadcast and streaming to see your favorite shows ASAP, or do you wait for the ultimate quality of Blu-ray?

Since Steve Jobs passed away, my inbox has been rife with rumors that his parting gift to the world will be a flat-panel television. Actually, this rumor has been circulating all year, especially since LG Electronics has announced it will launch a 55-inch OLED TV in 2012, and LG Display makes the screens for various Apple products. Now that would be something—a large OLED flat panel running iOS with all those apps and Siri voice command.

Of course, such a product from Apple—which many are calling iTV—will undoubtedly sport a gorgeous design, an elegant user interface, and an exorbitant price. So my question is, if you had the bucks, would you be among the first to buy a 55-inch OLED iTV?

As regular readers of this site know, we strongly encourage all video enthusiasts to take a few minutes to tweak their display's basic picture controls—brightness, contrast, color, tint, and sharpness—to get the best possible picture quality short of a full professional calibration. There are several inexpensive Blu-rays and DVDs that provide all the images you need to accurately set these controls. My question is, which one do you use? Or do you watch your display without making these simple adjustments?

Yesterday, I posted a blog mourning the premature death of so-called "active retarder" 3D technology. That leaves two types of 3D flat panels to duke it out—those that quickly alternate the left and right images on the screen synchronized with active-shutter glasses and those that use a film patterned retarder (FPR) to alternately polarize the odd and even lines on the screen, which are isolated for each eye using passive-polarized glasses.

There are many pros and cons to consider with each technology. Active-shutter glasses unequivocally provide full 1080p resolution to each eye, but they also block more light from reaching the eyes than passive glasses, so the image is typically dimmer. In addition, many people complain about seeing a flickering effect with active glasses that is nonexistent with passive glasses, and active systems are more prone to crosstalk/ghosting. And don't forget that active glasses are much more expensive than passive glasses, not to mention that active glasses are heavier, bulkier, and require replaceable or rechargeable batteries. On the other hand, while FPR displays often have a wider horizontal viewing angle, they have a much narrower vertical viewing angle. And they might not deliver full 1080p to each eye, though this is hotly debated, as discussed in my recent blog.

So which 3D flat-panel technology do you prefer—active-shutter glasses as championed by Panasonic, Samsung, Sharp, and Sony, or FPR with passive glasses as espoused by LG, Toshiba, and Vizio? If you haven't actually experienced them, which one seems more appealing to you?
