Today's New York Times carries a brief obituary notice of the passing of audio innovator, Peter Pritchard, on August 23 in Austin, Texas at the age of 83. Peter founded Audio Dynamics Corporation in New Milford, CT in the early 1960's. His original ADC-1 ("Tip mass: 0.6 mg. Compliance. 20x10^–6cm/dyne, all directions. Playing weight: 1 gram or less in top quality arms") was a breakthrough product. Indeed, all ADC pickups were notable for their extremely high compliance and low tracking forces and he pursued this approach through a series of successful designs including the well-known ADC-10, ADC-25 and XLM cartridges. They were all based on his "induced magnet" principle, which derived from the older GE variable-reluctance cartridges that had been game-changers for affordable magnetic phono pick-ups in the 1950s.

Things move fast in multichannel. No, I'm not referring to the speed of sound effects as they whip around a room—let's leave that for the home-theater mags. I'm talking about audio technology. Since I began writing this column in June 2003, we've seen serious technological changes almost annually, some driven by real needs, some imposed by marketing considerations. To me, the rate of change seems strikingly rapid, compared to that of the products I review for the main portion of Stereophile, based, as they are, in the two-channel world.

Every few years, it seems, Sony offers a statement product. Sometimes they do it to define a new product category—the SCD-1 introduced to the world the SACD/CD player. Sometimes they do it because they can, as with the outstanding ES SS-M9 and ES SS-M9ED loudspeakers, enthusiastically reviewed by John Atkinson in Stereophile in September 1996 and August 2001, respectively. So when I heard that Sony would introduce a special new speaker at a "by invitation only" event at the 2011 Consumer Electronics Show last January, my interest was piqued. I've always kicked myself for not buying a pair of ES SS-M9s ($3500) when I could have. The ES SS-M9EDs were even better, said JA—and, at $16,000/pair, a lot more expensive. Now, a decade later, Sony has decided to make another "statement."

Kal reviews the Yamaha Aventage BD-A1000 universal Blu-ray player and remarks "a sharp-looking, great-sounding machine that will play any extant digital format well. It sounded better in my better system, where I could really relish its low-frequency performance." He also takes a listen to the Meridian 861 Reference v6 Digital Surround Controller and ponders "how to reconcile the internal complexity of Meridian's 861 Reference v6 with the disarming purity of the sounds it reproduces?"

As B&W's 800 Series has evolved, Stereophile has reported on its progress. Lewis Lipnick reviewed the Matrix 801 Series 2 in 1987, and Wes Phillips wrote about the Nautilus 801 in 1999. I reviewed the B&W 800 Signature in 2002 and the 802D in 2005. This is getting to be a habit.

The AV7005 is Marantz's second multichannel preamplifier-processor and, at $1499.99, the least expensive pre-pro I've used or reviewed. The Integra DTC-9.8, which has been resident in my stable since 2007, when it cost $1600, and its successors, have since then steadily risen in price. The Marantz's predecessor, the AV8003 ($2599.99), was highly praised in many quarters. I never got my hands on one because, like a churlish child, I felt it lacked features I considered essential. Other reviewers didn't seem bothered by those limitations, or were unaware of them. The AV7005, however, looks and feels like a winner for music and home theater. I see no evidence of skimping—the AV7005 sports such high-end features as balanced outputs, network controllability and streaming, and, of course, HDMI v1.4a for compatibility with 3D and all audio codecs.

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).

I remember my first experience with headphones. In 1960, I bought a set of Trimm dual 'phones (less than $5) and rewired them for stereo. The experience was remarkable for several reasons. First, it brought the sounds into my head—I was thrilled with the impact. Second, stereo effects, especially with Enoch Light's ping-pong LPs (eg, Provocative Percussion, Command RS800SD), were striking. Third, I could play them really loud without bothering others. Of course, they had no bass, brittle treble, distorted at high levels, and their wire headband and Bakelite earpieces were uncomfortable. My fascination with this gimmick quickly faded.

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.

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.
