Tube Preamp Reviews

Cary Audio Design CAD-5500 "CD Processor" preamplifier

A "CD processor," is how I distinctly heard Cary Audio's Dennis Had describe it. The venue was Stereophile's High End Hi-Fi Show in New York last April. Nothing really unusual in today's digital marketplace, I thought to myself, though a bit out of character for a company dedicated to vacuum-tube technology. But wait a minute. Dennis had described it as an analog CD processor. Analog!? Well, yes, the unit processes the analog signal from a CD player.

Lamm Industries LL2 Deluxe preamplifier

On the first morning in June I opened all the windows in my listening room and played Classic Records' LP reissue of Dvorák's Cello Concerto (RCA Living Stereo LSC-2490), with Piatigorsky and the Boston Symphony Orchestra. The sunny weather put me in a fine mood, and so did the sound of my music system, which made me feel prouder than usual: Was ever a Linn record player more expertly adjusted? Wasn't I smart for keeping those Lamm monoblock amplifiers? Could a pair of Quads possibly sound better than mine?

Aesthetix Saturn Calypso line preamplifier

A straight wire with gain? That's what a line stage is supposed to provide, but few in my experience actually accomplish it, and I'm not sure that most audiophiles would really want it that way. Some want a bit of tightening and brightening, while some prefer a bit of added warmth and richness. But whatever the preference, none of us wants too much of a good thing—the tighter, brighter line stages better not sound etchy and hard, and the warmer, richer ones better not sound thick and plodding.

Audio Research Reference 1 preamplifier & VT200 power amplifier

They say you never forget your first time. For me, it was an Audio Research SP-6B that had been heavily modified by Analogique in NYC—which meant, among other things, that yellow capacitors shunted other yellow capacitors all the way up to the top plate. That first taste of the High End—prior to that, you might say my face had been pressed against the window—was definitely love at first listen. That SP-6B was warm yet detailed, and I ended up building a system around it that at least one friend described as a huge musical wet kiss.

Audio Note M2 Balanced Phono preamplifier

The first time I heard an Audio Note preamp was seven or eight years ago, when I sampled their entry-level M1—a refreshingly musical thing that brought the same kind of color and drama to preamplification that Audio Note's more famous products brought to the driving of speakers. And the M1 cost only $1250 at the time, with phono stage. (Newcomers, please don't wince: That's awfully cheap for what it was.)

Fosgate Audionics FAP V1 surround processor-preamplifier

When PR guy Adam Sohmer first told me about the Fosgate Audionics FAP V1, I thought that the impressive-looking device would be the first all-tube preamp-processor—heck, the first tube anything—in my multichannel system. Then I looked closer at the user's manual I'd downloaded from Fosgate's website. Hmmm. No Dolby Digital, no DTS—just Dolby Pro Logic. Of course, the FAP V1 is Jim Fosgate's signature expression of Dolby Pro Logic, and I guess that counts for something. But the more I thought about it, the more interesting a prospect the FAP V1 seemed.

Balanced Audio Technology VK-50SE line preamplifier

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.

Jadis RC JP80 MC Mk.II preamplifier

"It costs as much as a car—and not a used jalopy, either." That's what goes through your head as you contemplate this magnificent $20,190 piece of audio jewelry. I don't mean "jewelry" pejoratively; the tubed Jadis RC JP80 MC Mk.II is a gorgeous, gleaming hunk of retro-looking machinery. Two hunks, actually: an equally large remote power supply is connected via an umbilical cord terminated with an elbow connector the size of house plumbing.

Cary SLP-98P tube preamplifier

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.
