McIntosh C1000 preamplifier system

Still burning in my bank of childhood memories are misty images of the glowing green lettering on the McIntosh tube preamps and tuners that populated the windows of the audio stores that once lined lower Manhattan's Cortlandt Street. Leonard's and most of those other retailers are long gone—as are most of the audio brands that shared their windows with McIntosh, and that once symbolized the might of American innovation and manufacturing. Even the World Trade Center, the controversial complex that replaced Cortlandt Street's "Radio Row," where the hi-fi industry was born, is tragically gone.


EAR 912 preamplifier

My opinions keep changing—more evidence of life before death, I suppose—including my thoughts on audio-system hierarchies. I used to think that preamps were among the most sonically influential components, certainly more so than power amplifiers. I'm not so sure anymore (footnote 1).


Balanced Audio Technology VK-3iX preamplifier & & VK-55 power amplifier

It's been 10 years since Balanced Audio Technology (BAT) introduced their first products: the VK-5 line-stage preamplifier and the VK-60 power amplifier. (I reviewed">http://www.stereophile.com/tubepoweramps/766">reviewed both in the December 1995 Stereophile, Vol.18 No.12.) The success of these and other BAT products has allowed designer Victor">http://www.stereophile.com/interviews/767">Victor Khomenko (the "VK" of the model designations) and partner Steve Bednarski to quit their day jobs at Hewlett-Packard; they were joined by Geoff Poor as a partner to handle the sales end of the enterprise. BAT's current lineup includes several preamps, phono stages, a CD player, and tube as well as solid-state amplifiers. The top of BAT's preamp range is the VK-51SEhttp://www.stereophile.com/tubepreamps/1103bat">VK-51SE;, which costs $9000; their top tube power amp is the VK-150SE">http://www.stereophile.com/tubepoweramps/536">VK-150SE monoblock ($17,000/pair); if you want their best phono stage, the VK-P10http://www.stereophile.com/phonopreamps/871">VK-P10; will set you back $8000.


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 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.


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.
