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).

It doesn't take a genius to appreciate the audacity of naming a company after Albert Einstein, the iconic science and math whiz. Clearly, company founder and owner Volker Bohlmeier knew what he was doing—this German brand of boutique electronics has enjoyed worldwide critical and marketplace success since its founding more than 20 years ago.

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.

This is an era in which products and websites are "launched," but in the past two years Herron Audio has sort of oozed its way into the public ear. With little visible promotion or splashy advertising, Herron is now spoken of within an ever-widening audiophile circle.

There's a whorish aspect to reviewing that some readers and industry critics never tire of mentioning, as if they've stumbled onto some great revelation: that we writers seem to flit from new product to new product, sometimes gushing like cracked fire hydrants over one amplifier one month, only to gush over another amp the following month.

In its comparatively few years in the marketplace, the line-level preamplifier appears to have established commercial parity with its full-function big brother. That this was inevitable was clear as far back as the mid-'80s. The advent of the CD and the proliferation of digital sources argued for a modular approach to preamp design. In such an environment, line-level sources (eg, DAT, CD, even analog tape) deserve special attention.

"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.

The L2 Reference sits at the top of Lamm Industries' preamplifier line. According to the manual, its "unique" circuitry uses specially selected, superlinear, high-voltage MOSFET transistors that ensure class-A operation from input to output, with no overall negative feedback at any stage. All stages, including the high-current output buffers, are single-ended.

I've long been impressed by the design, construction, and sound of the tubed electronics produced by Vladimir Lamm, but I'd never had a Lamm Industries product in my house. So I asked for a review sample of Lamm's flagship line-stage preamplifier, the LL1 Signature.

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?

The Lazarus, a slim, quite elegant unit finished in black with red and gray legends, lived up to its advance billing: it literally rose from the dead! Out of its coffin (ie, shipping box) and plugged into the wall, it showed no signs of life. Troubleshooting revealed a blown AC mains fuse. That in itself was not a major problem, but what worried me was the root cause of the trouble. Preamplifiers as a rule are not power-hungry, so a current surge at turn-on sufficient to destroy the 250mA slow-blow mains fuse appeared symptomatic of a major circuitry failure.

This is a true story about a surprising 1W integrated amplifier—a push-pull, class-A, output-transformerless tube amp—that drove my DeVore Fidelity Orangutan O/93 speakers to 90dB average levels with grace, spiderweb detail, liquidity, and—unbelievably—a small degree of bass slam.

If you travel along Route 20 in upstate New York, you might see the hitchhiker my family and I refer to as the Old Soldier—so called because this slightly built man, whose age could be anywhere from 55 to 90, is always dressed in a military uniform from some long-ago campaign. When we first saw him, his topcoat suggested a recent return from Chateau-Thierry; in more recent sightings, the old man has taken to wearing the trim khakis and sharply creased legionnaire cap of the late 1940s—chronological zigzagging that made me think, at first, that this traveler was aging in reverse.

In January of 2014, some of us wondered if the sudden death of designer Ken Shindo would spell the end of the company he founded in 1977: It was hard to imagine Shindo Laboratory being led by anyone but its founder, a former Matsushita engineer who made it his life's work to study not only the designs of audio's golden age, but to learn the sound of every vacuum tube, every passive part, every circuit variation that he might reasonably press into service.
