Infinity Composition Prelude P-FR loudspeaker

I can't think of two products at further ends of the audio spectrum than a single-ended triode tubed amplifier and a mass-market Home Theater loudspeaker. Single-ended tubed amplifiers are about reproducing subtlety, delicacy, nuance, and communicating the music's inner essence. Conversely, a Home Theater loudspeaker system—particularly one made by a mass-market manufacturer—would appear to put the emphasis on booming bass and reproducing shotgun blasts, with little regard for musical refinement.

What a bizarre marriage it was, then, to pair the new Infinity Composition Prelude P-FR loudspeakers with the Cary Audio Design CAD-300SEI 11W single-ended triode amplifier (reviewed elsewhere in this issue). This combination didn't happen by accident; as you'll see, these apparently disparate products are a match made in heaven.

I discovered the Infinity Preludes while surveying Home Theater loudspeaker systems for the upcoming second issue of the Stereophile Guide to Home Theater. In addition to evaluating the loudspeaker systems under review with video soundtracks, I assessed their musical qualities—or lack thereof. The Preludes were such a musical standout that I rescued them from the Home Theater room (where they had been powered by mass-market receivers and fed with a laserdisc source) and gave them a new lease on life in the larger music room, with reference-quality source and amplification components. The Preludes' extraordinary musical performance and unique design compelled me to tell you about how they performed in an audiophile-quality two-channel playback system.

Getting Started & Greatest Bits

I’m sort of a jerk (stubborn, old-fashioned, anti-social, fiercely independent) and have managed, for my entire adult life, to survive without the Internet in my home. I realize that that will someday have to change&#151probably sooner than later&#151as I relinquish my autonomous life for one shared with another person. (And her two cats.)

For many people, the Internet means access to email, social networking sites, weblogs, forums, countless apps and other crap. For me, the Internet will inevitably mean Computer Audio.

And when the time comes for me to dive into Computer Audio, I’ll rely on Michael Lavorgna’s AudioStream to lead the way.

Getting Back into Vinyl Hi-fi: Part 3

Larry listens to the Usher S-520s with the tweeters on the inside first.

After an exhausting but educational day at NYC’s In Living Stereo setting up my new Rega RB101 tonearm with the Audio Technica AT95E phono cartridge, I hailed a taxi while balancing the turntable on one hand. Thirty minutes later, the yellow cab stopped at the doorstep of my quaint Brooklyn duplex, which I share with three other roommates, a Chartreux cat named Larry, and three friendly Pakistani families.

Upon my return home with the P1, the roommates were ecstatic. Jared analyzed, “I dig its minimalist design.” Leeor cheered, “I can’t wait to play the new Animal Collective record on this!” Darryl insisted, “Yo, you need to bring some bitties back now.” Larry the Cat ignored our excitement and cuddled with my phono preamp’s glowing tube. After listening to some records together, I kicked the roommates out for some alone time with my system. No bitties yet, but I did have a mug of green tea, some LPs, and Larry.

Siefert Maxim III loudspeaker

While it is not quite accurate to say that $500/pair loudspeakers are a dime a dozen, they are by no means unusual. And since this is a price area where major design compromises are mandatory (footnote 1), the sound of such loudspeakers tends to vary all over the map, from pretty good to godawful—depending on what performance areas the designer chose to compromise and by how much.

I approached this latest half-grander with little enthusiasm, despite Siefert's persuasive literature, I have, after all, been reading such self-congratulatory hype abiout new products for longer than most Stereophile readers have been counting birthdays. This, I must admit, was ho-humsville.

Mark Levinson's Milestone Year

Mark Levinson, born December 11, 1946, celebrates an important anniversary in 2002. Exactly 30 years ago he jogged onto the playing field of high-end audio, so early in the game that fans, then few and far between, could count the players on their fingers.

The high-fidelity industry seems a logical home for a jazz musician like Levinson, who once envisioned a career playing flugelhorn and double bass, but his voyage into audio was a detour that could be said to have begun at age 22, when he took a job working on a film about Joan Baez. "It was a joy to find people willing to pay me to do something," quips the trim, youthful 55-year-old, who is quick to recall his "nonexistent income as a musician."

Loudspeaker Pioneer Bill Hecht Passes at 89

A press release issued by MSE Audio September 13 announced that William (Bill) Hecht, a died Tuesday September 11 in New York after a brief illness. He was 89 years old. In 1955 Hecht founded United Speaker Systems, an OEM manufacturer of speakers and related electronics, and also founded Phase Technology Corporation with his son Ken. (See Stereophile's positive review of the Phase Technology PC80 speaker here.) Phase Technology was later acquired by MSE Audio.

Nelson-Reed 1204 subwoofer

I was so impressed by the Nelson-Reed 8-04/B loudspeaker's low-end range that I seriously doubted the add-on subwoofers could add enough of significance to be cost-effective.

I was wrong.

Two of the subwoofers were provided, along with the necessary electronic crossover unit. Each 1204 unit contains four 12" woofers in a very solid sealed enclosure, with two facing to the front and two facing the rear. The electronic crossover has three controls, besides the AC power switch: a hardwire (footnote 1) bypass switch, a stereo/mono switch, and a subwoofer level control. In the stereo mode, the low frequencies are kept separate, left from right; in mono mode, they are blended together for feeding to a single subwoofer. I will not resurrect the question of whether or not it is important to maintain stereo separation into the LF range, except to echo N-R's observation that there is no LF separation on analog discs to begin with; the lows are mixed together, to limit vertical excursions of the cutting stylus that could cause it to rise above the disc surface or, worse, dig into the aluminum base of the master disc.

Ulrik Poulsen and his Amazing Alpha-Core Cables

Jonathan Scull: How long have you been making cables, Ulrik?

Ulrik Poulsen: It's actually close to three years now...It's a spinoff from other products we make. Actually, Alpha-Core manufactures magnetic cores and various materials and components for transformers...And we have a daughter company called Tortran that manufactures toroidal transformers. Anyway, five years ago we introduced a new product called Laminax. It's a combination of copper and aluminum with various kinds of dielectrics. This is laminated together continuously in various fashions to produce a material that's used as shielding for EMI and RFI in the electronics industry.
