Just who does Bruce Rozenblit think he is? And why is he saying those things about the late Julius Futterman? Rozenblit, relying heavily for guidance on his Electrical Engineering degree, has crafted an OTL (output-transformerless) amplifier that flies in the face of contemporary design dogma. To hear Bruce tell it, he's tamed the breed—this is how OTLs should have been done to start with, Futterman notwithstanding.
At the last few audio shows, whenever I heard a pair of the big Cary CAD-1610-SEs, I fair licked my chops. The two-tiered monoblock looked positively stunning in black and polished aluminum, exotic tubes bristling from the top "floor" of its two-story edifice. The Cary always induced pelvic tilt in me—you know, when your lizard brain takes over and tube lust is in the air.
I'm always eager to fulfill my prime Stereophile directive: "To go where no audiophile has gone before," as JA often quips. As it happens, I've long suffered an itch to audition OTL (output-transformer–less) amplifiers, wondering how eliminating the output transformer might affect the sound. Enter the Graaf GM 200, with nothing but wire between its power tubes and the crossover.
Just what is the absolute sound, and how do you get there from here? What the heck are we looking for as we endure the mirth of others while purposefully setting up our high-end systems? Is it, indeed, the sanctified sound of acoustic instruments in real space? Can we ever really achieve that? Or is it the accurate realization of the signal on the master tape? Or—as was recently suggested at the New York Noise single-ended lovefest, covered in this issue's "Industry Update"—are some of us looking for the emotion and the artist's intent?
John Atkinson flapped his bushy eyebrows at me and smiled slyly. "Hey, J-10, why don't you do the Sony SCD-C333ES SACD carousel player for April?" Usually, when JA gets that look on his face, I seek shelter. The phone bripped suddenly in my office, but I knew it was too late. "Oooo-kay..." I smiled back, thinking of Stereophile's recent covers and the hubbub, bub, thick as it comes, that they'd produced. (See "Letters" in the February and March issues.)
Kathleen (K-10) and I first met Jack Renner—Telarc's Chairman, CEO, and Chief Recording Engineer—at Iridium, a tony jazz club here in New York. He was recording Benny Golson and the Jazz Messengers doing a rousing a tribute to Art Blakey. Now what would you think a guy who's won 31 Grammys over 21 years would be doing, exactly? Maybe feet up, a cigar languidly tracing curlicues in the air while directing his minions?
I suppose that most high-end designers dream about making a Statement Product—their best effort, without regard for price. Victor Khomenko, majordomo of Balanced Audio Technology, got the bug and came up with the VK-50SE. This hugely full-functioned line-stage preamp derives its Special Edition (SE) moniker from the eight hot-running, super-hush-hush Russian 6H30 Reflector SuperTubes that populate the circuit board.
Pass Laboratories' X amplifier series represents the efforts of designer Nelson Pass to prove that simple linear amplifier topologies can be scaled to provide high-quality audio performance at very high power levels. The handsome X1000 monoblock under scrutiny here, the largest and most powerful amp in the Pass stable, makes 1000W into 8 ohms and a mighty 2000W into 4 ohms. The amplifier has no global negative feedback, and only two gain stages: the front-end provides all the voltage gain and feeds a high-current follower stage.
