Sonos ZP80 & ZP100 WiFi Music System

Don't get the wrong idea. I don't watch trash TV. I am not interested in the doings of people who are famous merely for being famous. I was probably the last to realize that Paris Hilton was not the name of a French hotel. But the kitchen TV just happened be tuned to Channel 4 when I switched it on while I was preparing dinner. No, I do not watch NBC's Extra, but as I was reaching for the remote I was stopped in my tracks by what I saw. The show was doing a segment on the new L.A. home of Jessica Aguilera, or Christina Simpson, or . . . well, it doesn't matter. What does matter was the host's mention of all the cool stuff the bimbette had had installed in her new pied-à-terre: "...and a Sonos audio system, of course."

Sony TA-P9000ES multichannel analog preamplifier

Sony describes the $700 TA-P9000ES as "a pure audio multichannel preamplifier equipped with two inputs for 5.1 analog multichannel audio sources, enabling selection, volume control, and amplification." A relay with twin gold-plated crossbars switches the two six-channel sources. Then follows a class-A solid-state push-pull amplifier in discrete configuration. Separate transistors, resistors, and capacitors populate the printed circuit boards. An oxygen-free copper shield surrounds each channel to prevent crosstalk between the channels. In addition, there is a relay-controlled gain stage offering 0, +6, and +12dB amplification.

Soundsmith SMMC1 moving-iron phono cartridge

The audio industry may have lost a legend and a prolific innovator in Henry">http://www.stereophile.com/news/11260">Henry Kloss a few years back, but it still has another affable, creative eccentric in Peter">http://blog.stereophile.com/ces2008/011008smith/">Peter Ledermann. In the mid-1970s, Ledermann was director of engineering at Bozakhttp://www.stereophile.com/historical/1005bozak">Bozak;, where, with Rudy Bozak, he helped develop a miniature bookshelf speaker and a miniature powered subwoofer. Before that, Ledermann was a design engineer at RAM Audio Systems, working with Richard Majestic on the designs of everything from high-power, minimal-feedback power amplifiers and preamplifiers to phono cartridge systems. He was also an award-winning senior research engineer at IBM, and the primary inventor of 11 IBM patents.

Spectrum Audio 108cd loudspeaker

Tricker tweets? I know, Halloween has already come and gone, but I just had to use that because this little speaker has a trick about its tweeter. The Spectrum Audio 108cd is constructed of ¾" MDF for the baffle and ½" MDF for the sides, with a very–high-quality black ash vinyl covering all the way around. (A brown ash finish is also available.) Rapping on the cabinet results in a hollow bonk, rather than a solid thud.

Spica SC-50i loudspeaker

This is a speaker we've been fairly intimate with over quite a period of time. Designed by John Bau, the SC-50i started out three years ago as an inexpensive speaker system ($330/pair) not sold through dealers.

One of the factors allowing it to cost so little was the clever adaptation of cardboard tubes, normally used as forms for pouring concrete pillars, for use as speaker enclosures. They have a number of advantages, other than low cost: their circular form helps eliminate resonance of the back wave within the enclosure; the material is rigid because of its shape, and is non-resonant due to its construction.

Spica TC-50 loudspeaker

High-quality, low-cost loudspeaker systems are not an everyday blessing. The Rogers LS3/5a has survived for more than a decade precisely because so few US manufacturers sought musical accuracy as distinguished from high output and powerful bass. The economics of loudspeaker manufacture also don't lend themselves to economy. The cost of woodwork is driving the price of speakers up almost as fast as the cost of sheet-metal work is escalating the price of electronics.

Spica TC-60 loudspeaker

As far as I can tell, Santa Fe–based speaker engineer John">http://www.stereophile.com/interviews/694">John Bau had designed but four commercial loudspeakers before the TC-60 was launched at the 1994 Winter CES: in order of appearance, they were the Spica SC50i (1980), the TC-50http://www.stereophile.com/standloudspeakers/446">TC-50; (1983), the Angelushttp://www.stereophile.com/floorloudspeakers/693">Angelus; (1987), and the SC-30 (1989). None were expensive, and all garnered much praise, both in Stereophile's pages and elsewhere.

Sumiko Blue Point & Blue Point Special phono cartridges

In these waning days of Analog's Last Stand, it might seem absurd to review midpriced phono cartridges when this space could be given instead to the gear Stereophile usually covers—like $3000 OTL tube amps built by guys like that "Rainbow Man" lone nut who used to dance in the stands at Super Bowls before he took hostages in a hotel room with a .45 screaming, "MIT CAPACITORS!!! MIT CAPACITORS!!!"
