How much amplifier power do you need? Most audiophiles figure a maximum of a few hundred watts per channel—beyond that, you're wasting your money or showing off. Others think that anything more than a few watts will mess up an amplifier's musical coherence or "purity," so they stop there and find uncommonly sensitive speakers, usually compression horns with cone woofers.

"Onkyo Returns to its Stereo Roots to Debut New Digital Amplifier Technology." This heading of the press release for Onkyo's A-9555 digital integrated amplifier was surely intended to warm the cockles of the two-channel audiophile's heart. Some of us remember the Onkyo Grand Integra amplifiers of the 1980s, which were considered competitive with the big Krells and Mark Levinsons of the day. To refresh my memory, I looked through my <I>Stereophile</I> archives and found the December 1985 issue (Vol.8 No.8), which included Larry Greenhill's review of the Grand Integra M-510, a 300Wpc power amplifier covered in lacquered persimmon wood, weighing 139 lbs, and costing $4200 (about $8000 in 2007 dollars). Larry was most impressed with the M-510, describing it as "a very powerful amplifier with outstanding sonics across the board&mdash;power with delicacy."

"Why didn't they choose a color set?" I had been reminiscing about the early days of TV and how my parents bought a black-and-white set so we could watch the Coronation of Queen Elizabeth II in 1953. My daughter Emily's question had me stumped. It is difficult to explain to someone born 10 years after the launch of CD—someone who, for example, has never seen, let alone used, a typewriter, and who enjoys a comparatively infinite set of choices among mature 21st-century technologies—that it was not always thus.
