Tube Preamp Reviews

I suppose that most high-end designers dream about making a Statement Product—their best effort, without regard for price. Victor">http://www.stereophile.com/interviews/767">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.

Rudyard Kipling said that "never the twain shall meet." He was speaking of East and West, but in the world of audio, his adage has most often been applied to what has been the traditional chasm between the sounds of tubes and solid-state. Tube advocates thump the tub for the timbral and spatial glow, the absence of harsh, odd-order harmonic distortions, the harmonic completeness and holistic spatiality that only fire bottles can provide. Solid-state advocates point out the superiority of their preferred gear in terms of bass depth, power and control, low noise, and ultimate detail resolution. That chasm between the characteristic sounds of tube and transistor has narrowed appreciably in the latest generations of gear, as each type of circuit has become capable of embodying some of the other's trademark characteristics. But between the camps, friendly competition continues.

Several issues back, we reviewed rather enthusiastically a pre-production prototype of this preamp. The original was an unprepossessing-looking device on two chassis, interconnected by a 3' umbilical, with a squat little preamp box and an even squatter power supply with humongous cans sticking out the top. We averred that it sounded nice. The production model is so nicely styled and functionally smooth that we wondered if it might not be another Japanese product. 'T'ain't.

Ideally, through the medium of a synergistically balanced set of high-resolution components, we seek to re-create an acoustic event with a palpable sense of realism—as in timbre, dynamics, room cues, and dimensionality. Have I ever experienced a system commensurate with the experience of sitting 12th-row-center at Carnegie Hall for Boulez conducting Stravinsky? Close, but...

Just when I thought my equipment reviewing schedule was locked in for many months, an unavoidable last-minute cancellation sent me scrambling for an alternative.

Jim Austin to the rescue. To his query, "How would you like to review a tube preamp from Canor, of Slovakia?" I answered with an enthusiastic "yes!"

In addition to the exciting prospect of reviewing the first tubed preamplifier to come my way in a long time, hearing the Canor Hyperion P1 preamplifier ($12,500) in my system would enable me to get a handle on the sound of gear I'd only encountered once, at High End Munich 2024. As is often the case at shows, I left without a clear sense of the preamp's contribution to the system's sound, let alone its ultimate potential.

RCA's time-honored 6SN7 may be the coolest tube of all. The octal-based dual-triode has its own Wikipedia entry—something not even the 2A3 or 300B can boast—along with its own websitehttp://www.6SN7.com">website;. The 6SN7 is chunky, rugged, and handsome. Best of all, it's available, probably because people keep coming up with very good uses for it. In that sense, the 6SN7 is the Campbell's Cream of Mushroom Soup of the tube world.

I had it all wrong. I assumed that the "SLP" in SLP-98P stood for stereo line preamplifier. But Dennis">http://www.stereophile.com/interviews/399">Dennis Had, Cary Audio's founder and chief designer, told me that it actually stands for sweet little preamplifier. In a day and age when acme is a word without meaning and the fighting Irish are neither, this strikes me as a risky marketing gambit—but one that may be effective if the name proves true.
