As I wandered the displays and demonstrations at the 2010 CEDIA Expo last September, I found few multichannel products worth writing about. Sure, there were many interesting new speakers from Pioneer, GoldenEar, Atlantic Technology, Adam Audio, MartinLogan, and others, but really, you could just use two for stereo. I saw the requisite number of new multichannel players, processors, and receivers, but most boasted no more than some new features that made them easier to use (iPad apps were rife) and/or gave them access to new sources (audio and video streaming were obligatory).

When it comes to ripping CDs and downloading music, I've been sitting on the sidelines feeling more than a bit of envy. Stereophile's reviews of various media servers have whetted my appetite, but not so much as to overcome my timidity about getting into a new realm of technology in which I would be a beginner all over again. Still, I've sneaked a few peeks.

Back in Atlanta's World Congress Center for the second year it is hot (around 90°F) and humid outside but it is cool at the 2010 CEDIA Exposition. On the very first full day, I found a slew of interesting new loudspeakers and that's despite having seen less than a third of the Show floor. Undoubtedly more will be discovered but it is great to say that all of the most intriguing new ones are relatively inexpensive.

When I started out on my multichannel mission in 2000, it was with an all-digital Meridian system that relied on lossy, compressed sources like the original Dolby Digital and DTS formats, or on synthesized surround based on Dolby Pro-Logic or Meridian's own TriField. With the appearance of first SACD and DVD-Audio and then Blu-ray, discrete lossless multichannel recordings became available, but there was no way to output those signals in digital form for interconnection to other components for playback or further manipulation. Most audiophiles, me included, already had analog preamps and power amps. It was only with the appearance of HDMI and the accompanying HDCP content protection that we could output those digital signals, and over a single cable to boot. Today, there are A/V receivers, some costing less than $500, and more than a handful of audiophile-oriented preamp-processors, that can accept such lossless high-resolution multichannel content as PCM, DSD, Dolby TruHD, and dtsHD Master Audio.
