Knoll Systems or Richmond, BC has announced two new projectors built by the company from the ground up: the HDP1100 and the HDP1200. Both are single-chip DLP designs with 7-segment color wheels said to "virtually" eliminate rainbow artifacts. The projectors are available with either sort- or long-throw, all glass Nikon lenses, and offer an anamorphic aspect ratio for use with 2.35:1 screens and add-on anamorphic lenses. The HDP-1100 ($5999) is short-throw, while the HDP-1200 ($6799) is long-throw.

New amps from Krell are always hot news for audiophiles, and these two would also be at home in a high-end home theater. The S-275 2-channel amp ($5500) sports 275Wpc into 8 ohms and 550Wpc into 4 ohms. Two of them are shown on top. LIke all Krell amps, this one is also comfortable into almost any load, even very low impedances. Switches allow easy bridging, producing a powerful monoblock.

Kuro Is So 2007
Tom Norton  |  Jan 08, 2008

Pioneer’s current Kuro plasmas may be the hot ticket this year, but there’s more in store. It isn’t sure when we’ll see the result of the company’s latest design effort, the Extreme Contrast Concept, in stores. I’m hoping for this time next year, because this is what we have all been waiting for: blacks as dark and rich as the very best CRTs of the past. No, not <I>as</I> good. Even better.

LED Inside
Tom Norton  |  Jan 09, 2007

Samsung now has several RPTVs that use LEDs for illumination instead of a projection lamp. This is the largest of the new models, the HL-6187S at 61". It's a full 1920x1080 (as are most all of the sets we are discussing here), with a slim depth of 14.4" and a claimed contrast ratio of 10,000:1. Contrast ratio is now officially the video equivalent of the old audio wattage race.

LEDs Lighten Up
Tom Norton  |  Sep 02, 2009
Projectiondesign will be introducing its Avielo Chroma DLP projector with LED illumination. No price was available at press time. The projector is said to produce a wider and more consistent color gamut with its red, green, and Blue LEDs. While the desirability of a wider gamut is debatable given the standard HD color gamut that most program sources use (a playback gamut that's wider than the source simply distorts the colors), more consistent color is always welcome. And unlike conventional lamp-based projectors, the Avielo Chroma's LEDs are said to produce the same color balance throughout their claimed lifetime of 50,000 hours.

LEDs, OLEDs, and Micro LEDs
Tom Norton  |  Feb 13, 2025
This blog will be old-hat for many veteran Sound & Vision readers, but there are always newbies flummoxed by this whole LED vs OLED vs Micro LED business.

The oldest and most basic form of a flat screen television is the LCD, or Liquid Crystal Display. A layer of liquid crystals is sandwiched between two layers of polarizing filters. When an electric signal is applied to those filters (that signal being the source to be displayed) the liquid crystals align in changing patterns to produce the moving and (where needed) color image.
