Tube Preamp Reviews

I must admit that, for a long time, I found it difficult to accept the idea that a major portion of one's audio budget should be spent on the preamplifier. Speakers, yes—they produce the sound; amps drive the speakers, so they're important. And source components? Well, everyone knows it's garbage in/garbage out. But a preamp? Even the name suggests something that's not quite the real thing, like pre-school, pre-med, or premature. Unlike amplifiers, they don't have to contend with loads that sometimes approach a short circuit, and heat dissipation is not normally a problem. What's the big deal?

As I write, it is garage-sale season here again in Santa Fe, and a recent sign near my home advertised "Over 3000 LPs, good condition, low prices." To my surprise, the seller wasn't a yuppie enamored of his new CD player but a true collector discarding the duplicates and dogs from his collection. 30 minutes later, many LPs heavier—including a mint Flanders & Swan At the Drop of a Hat (footnote 1)—and not too many dollars lighter, I returned to a great night's listening courtesy of the black vinyl disc.

It takes more than passing courage to make another assault on building the world's best tube preamplifier. You face stiff competition from well-established firms like Audio Research, Conrad Johnson, and Counterpoint. Such units can't be made inexpensively, and you face the steadily growing problem of tube supply: it is getting harder and harder to get tubes that are stable, have predictable sound and performance characteristics, and are long-lived. And you have to show audiophiles who have been burned before that you will still be around when they need service.

In appearance the Counterpoint SA-7 tube preamplifier is quite attractive, possessing the thin, low-profile look currently in vogue. There is a mute switch which (if you remember to use it) protects your amplifier from the preamp's turn-on and turn-off thumps. Unfortunately, the volume control on my unit didn't track accurately, and it was necessary to adjust balance with each change in volume. One unusual feature: the balance control allows very fine gradations in balance adjustment (a large movement of the control results in a small change in balance).

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).

Have you ever walked through fresh snow in the woods with all your senses heightened? When I did, shortly before the New Year, it was as if I was seeing nature for the first time, through a fresh lens. Never had white-coated surfaces appeared so white. Nor had shapes seemed so magical. It felt as if I had happened upon a pristine landscape unexplored by human or beast.

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.
