Integrated Amp Reviews

Besides my 20th wedding anniversary and the 15th anniversary of Listener magazine's first issue, this year marks the 25th anniversary of Roksan Audio Ltd., easily one of the most innovative design and manufacturing firms in British audio. Before Roksan came upon the scene in 1985, none of us had ever seen a loudspeaker whose tweeter was isolated from its surroundings by a sprung suspension. Or a commercial phono preamplifier designed to fit inside a turntable, just a centimeter away from the tonearm base. And who among us could have guessed that the Linn">http://www.stereophile.com/turntables/1103linn">Linn LP12's hegemony—among flat-earthers, I mean—would be broken by a turntable from outside of Scotland? Yet the Roksan Darius loudspeaker, Artaxerxes phono stage, and, above all, Xerxes turntable accomplished those things and more, to the genuine surprise of nearly everyone—and to the benefit of our industry at large, as other firms took those ideas and ran with them.

To celebrate his 30 years with the company, Marantz threw designer Ken Ishiwata a birthday party in the form of an assignment: Design a new, limited-edition integrated amplifier and SACD/CD player bearing his initials. (Only 500 of each will be made worldwide.)

Years ago, when I taught high school choirs, I had many types of kids in my ensembles. Though none exclusively fit the overly stereotypical lineup of kids on Fox TV's Glee, I always managed to have a nice assortment of jocks, preps, goths, motorheads, geeks, wastoids, and dweebs. One of the things that always fascinated me was how the big, tough jocks would turn out to be the most sensitive, emotional singers. It was always a touching moment when an otherwise stoic football star or wrestler would get all misty while singing the final song of the year-end concert. It showed me that the toughest exteriors often hide the creamiest creampuffs.

As the 2009 Consumer Electronics Show neared its end, I wandered into Blue Light Audio's room, which was dominated by the innards of darTZeel's new NHB-458 monoblocks—think of a 3D "exploded" diagram and you'll be on target. So impressive was that display of brute engineering that I almost didn't notice the amplifier that was actually making the music: the CTH-8550 integrated ($20,300).

With the Music">http://www.stereophile.com/mediaservers/ta_music_player_media_streamer"… Player, T+A also sent along the Power Plant integrated amplifier ($2700). The Power Plant (PP) looks almost identical to the MP, and the two comprise a handsome, fully functional audio system in a single modest stack. To make this even easier, you connect the two at their rear panels with a supplied RJ-12 cable (T+A calls this the E Link), which coordinates their functions and allows the MP and PP to be operated with a single remote control.

After Fred">http://www.stereophile.com/solidpreamps/1207bo">Fred Kaplan reviewed Boulder Amplifiers' 810 line preamplifier and 860 power amplifier for the December 2007 Stereophile, John Atkinson requested that I listen to the 860 in my own system for a while. Never having reviewed any Boulder kit, I was curious.

Winter has returned to Cherry Valley, New York, and I'm reminded of a bad habit that I used to conceal: On cold mornings I started my car well before driving off, then actually weighted down the accelerator pedal—with the heavy socket tray from my toolbox—in an effort to keep the idle high, and thus more quickly warm the windshield and the interior. Whether my lazy trick had the desired effect is a matter of some debate, but I wish now that I hadn't been so wasteful and so casually fouled the air.
