It's been three years since the February 1997 issue, when I last talked with Klaus Heymann, founder and chairman of HHN, the parent company of the Naxos and Marco Polo labels. When I heard that he'd be in New York for a visit, I jumped at the chance for another interview.
"Musical Fidelity X-10D" it said on the box. No, this is not bathtub mildew remover or laundry detergent. Actually, it's hard to figure out exactly what it is. The box is little help. Musical Fidelity calls the X-10D "the missing link," a "pure Class A CD-player accessory."
I've never written a love story before, but then, there's always a first time. This romance concerns the stunningly anthropomorhic Jadis Eurythmie II (mostly) horn speakers and the petite, jewel-like and vivacious Jadis SE300B ampsa 10W single-ended triode design with paralleled output tubes.
Kathleen and I, having flung ourselves into single-ended's embrace, have become, to some fashion, quite experienced. I've described the purity of presentation available with the Wavelength Audio Cardinal XS monoblocks when coupled with the Swiss-made Reference 3A Royal Master Controls in these pages (January '96). Using the Eurythmie speakers, which supplanted the 3As in our system, we've listened to Gordon Rankin's Wavelength Cardinal XS monos, the Kondo-san Audio Note Kasai parallel 300B stereo amplifier (next SE review to come), the ebullient and eager-to-please Cary 301SE 300B stereo unit, and the Jadis single-ended triodes, as well as our reference Jadis JA200s (yes, Jadis also does push-pull).
It's no secret. David Manley has not been big on single-ended amplifiers. Not enough muscle. You're better off with push-pull. Still, with a growing market for single-ended stuff, I'm sure Manley saw a need to do something. Of all tube designers, Manley has always been among the most prolific.
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 systemparticularly one made by a mass-market manufacturerwould 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 qualitiesor 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.
