Mozaex founder Douglas Kihm has been thinking about building a pair of super headphones since he was a kid, a dream he has finally realized with the BluWavs, which he is billing as the "world's first 7.1 discrete HD headphones." Each of the bulbous earcups contains five mini drivers, including what he calls a "vibration subwoofer" that literally shakes your head for a tactile experience. Each set of headphones comes with the Blender Console, which looks like a '70s-era equalizer and is available in analog and digital versions. In addition to a 15-band EQ for the front L/R channels, the blender has discrete level controls for each channel so you can really screw up...er, personalize the sound.

The 7.1-channel surround field was impressive while listening to DTS HD Master versions of the soundtrack for Tron Legacy, Peter Gabriel's Growing Up Live and Omar Hakim's Listen Up live jazz jam. Package prices range from $1,295 to $2,595, depending on the version of the Blender.

Black gloss has been the default finish for speakers for ages so when I saw a home theater suite of white-gloss speakers I stopped for a closer look. Adam Professional Audio, a German company known for its studio monitors, launched the ARTist Series line of consumer speakers speakers at CEDIA Expo with five powered models: the ARTist 3 and ARTist 5 bookshelf models with 2 x 25 and 2 x 50 watts of power, the ARTist 6 mini tower with 3 x 35 watts, the ARTist 6H center speaker with 3 x 35 watts and the ARTist Sub with 140 watts driving a 7-inch woofer.

The system's sonic character is defined by Adam's smooth sounding X-ART (eXtended Accelerating Ribbon Technology) tweeter, which improves on the Heil Air Motion Transformer concept developed in the '70s. Instead of the piston motion of conventional tweeters, a pleated diaphragm produces sound by squeezing air out like the bellows of an accordion, which is said to avoid distortion and dynamic limiting. Each speaker has RCA and XLR inputs and the bookshelf models also have USB and minijack connections. The ARTist system shown (ARTist 5s are used as surrounds) sells for $5,100 and, yes, the speakers are also available in black gloss.

Cary Audio has made a distinguished contribution to the headphone craze sweeping across the consumer electronics industry with the HH-1 headphone amp. Introduced at CEDIA Expo, the amp is designed and built in the U.S. and teams a tube preamp stage with a solid-state MOSFET output stage, chosen for its tube-like sonic characteristics. Featuring Class A operation at all output levels and a 30-second muting circuit to prevent annoying turn-on pops, the amp sports a pair of RCA inputs with loop-through outputs and is designed to drive headphones with impedances between 30 and 600 ohms. Price: $1,595.

The transition from analog to digital TV opened our eyes to a world of vivid images that we now take for granted, but technology marches on, with the promise of something bigger and better always just around the corner. As consumer electronics companies lay the groundwork for a 4K television/video format that delivers four times the resolution of regular HDTV and prepare to roll out the first 4K TVs, an 8K format is already on the horizon.
