8883aroyals.1.jpgThe match between amplifier and speaker for single-ended operation is critical, which is why John Atkinson suggested I let Wavelength's Gordon Rankin lead when it came to choosing a speaker to partner his special-edition Cardinal amplifiers. If you're not talking roughly 92dB sensitivity and a fairly benign load, say no lower than 6 ohms, you're just not talking single-ended. That precluded running the Cardinals on the big Avalon Ascents with their lowish 86dB sensitivity (in spite of the relatively benign impedance curve).

After more discussion it became evident that the best speakers to use were the very ones Gordon employed in his own reference system—the Swiss-made Reference 3A Royal Master Control loudspeakers.

As I had been impressed with Ted Denney's Synergistic Research cable, I thought that asking him for 25,000 words on his thoughts on cable design and performance would be an appropriate accompaniment to my Symphonic Line Kraft 400 amplifier review.

Things didn't start off auspiciously. I'd been after Symphonic Line's Klaus Bunge for more than a year to send me the Kraft 400 Reference monoblocks. Finally he called. He said he was going to be in town for a few days, and he had with him a pair of what he described as his "traveling" Kraft 400s, which he proposed to leave with me.

I'm not sure why, but people tell me things. Maybe it's because they realize I listen. They reveal themselves, sometimes in charming and unexpected ways. So I was almost prepared for my three-way conference call with the designer of the Symphonic Line Kraft 400 power amplifier, Rolf Gemein, in Germany and Indianapolis-based importer/distributor Klaus Bunge. I started by asking Rolf about his design philosophy . . .

Jonathan Scull: You say your YBA CD-1 Blue Laser CD player makes use of Stochastic Resonance, Yves-Bernard?

Yves-Bernard André: Yes...in adding some noise to the signal, we can actually get more information back.

Jonathan Scull: How long has VTL been in business, Luke?

Luke Manley: My dad, David Manley, and I co-founded VTL in June of 1986. We started small on the East Coast, and soon after we moved to California.

Scull: Is it because you're really a West Coast kind of guy?

Manley: [laughs] You bet! There's a lot of supporting industries out there; a big base of electronics manufacturers, for example.

Scull: What, in the San Francisco area?

ybacd101.jpgI'm about to out YYves-Bernard André as one of the great unknown tweakers of high-end audio. (My own predilection for stepping into uncharted tweakwaters is well known.) Yves-Bernard, his wife and partner Ariane Moran, and importer/distributor Daniel Jacques of Audio Plus Services seemed perfectly sanguine about letting the cat out of the bag. And why not? In a singular way, the YBA audio solution encompasses both the supertweak and the more-casual-about-equipment music lover.

The YBA CD 1 Blue Laser (or Lecteur CD 1, as it's known at home in France) breaks new ground. It is very French in that it's individualistic in the extreme, and perfectly embodies current thinking chez YBA regarding music playback in the home. Its design dates back to 1991, a point Yves-Bernard takes pains to point out in the manual.

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.

A true story: I got tagged for doing a howling 90mph on the way back to New York on the Jersey Turnpike late one night and got off with a warning.

I was pulled over by a beefy young Trooper, lights blinking furiously. Oops. [heh heh]. He saw Kathleen and I weren't nuts, checked the papers and my license, then checked out the Lexus very carefully with his flashlight. There was much oohing and ahhing.

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 amps—a 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).
