"Have you really listened to all those records?"

My guest, an occasionally nice person, didn't mean her question in a nice way. It was pointed and derisive: a needle intended to burst whatever it was that made me think filling a room with thousands of LPs was a good idea. She didn't wait for an answer—it would have been "Not quite"—but I half think she half expected me to see reason on the spot.

Years ago, while editing Listener Magazine, I received a call from a record-company publicist with whom I was friendly: The drummer Ginger Baker, whose work I admire, was promoting a new release, and we were offered a 30-minute telephone interview with the artist. I jumped at the chance, but wound up leaving the article in the can—partly because it was so short, partly because its subject was so cranky. As with vacation trips to certain locales, second prize would likely have been 60 minutes with Ginger Baker.

Domestic audio is based on two simple processes: transforming movement into electricity and electricity back into movement. Easy peasy.

Audio engineers have been doing those things for ages. Have they improved their craft to the same extent as the people who, over the same period of time, earned their livings making, say, automobiles and pharmaceuticals? I don't know. But if it were possible to spend an entire day driving a new car from 50 years ago, treating diabetes and erectile dysfunction with the treatments that were available 50 years ago, and listening to 50-year-old records on 50-year-old playback gear, the answer might seem more clear.

It's going to happen very soon.—Leonard Cohen, "The Great Event"

With a parts list that includes 18 new-old-stock Black Cat capacitors, 16 vintage-style Cosmos potentiometers, two Tango chokes, one Tango power transformer, and some of the loveliest steel casework I've seen on a contemporary product, no one could accuse Noriyuki Miyajima of skimping on the build quality of his company's only power amplifier, the Miyajima Laboratory Model 2010 ($9995, footnote 1). Then again, because the 2010 is an output-transformerless (OTL) tube amplifier, Miyajima-san spent considerably less on iron than would otherwise be the case. Think of the money he saved!

Listening #189: Luxman MQ-88uSE
Art Dudley  |  Aug 28, 2018  | 
For this month's column, I did something I've occasionally set out to do but never quite managed: I lived with a new power amplifier for nearly two months, used it to enjoy a variety of records, made scads of listening notes, and wrote most of the subjective portion of my review—all without knowing what was inside it.

Listening #200: Tzar DST1 & Shindo Montille CV 391
Art Dudley  |  Jul 25, 2019  | 
Products come and go. Some impress more than others, and in our little world, the ones that impress the most wind up in Class A of our semiannual "Recommended Components" feature.

After a product makes it to that list, if Stereophile's reviewers go more than a few years without hearing it again—in a home system or a dealer's showroom or even at an audio show—that product falls off the list, usually quietly. Thus, if a reviewer is maximally knocked out by a piece of playback gear, yet the fates allow neither a purchase nor an extended loan, he or she or someone else on staff must endeavor to borrow it again so it can stay recommended.

Listening #206: Shindo Cortese amplifier
Art Dudley  |  Jan 28, 2020  | 
Only recently did I learn that successive generations of the Chevrolet Corvette are referred to by the cognoscenti with two-character alpha-numeric identifiers: C1, C2, C3, and so on. I learned this while reading about the most recent version—C8, known to non-cognoscenti as the 2020 Corvette—which happens to be the first version since C2 that impresses me. (I say that as one who used to work for the owner of a C3, a then-middle-aged male who actually boasted, while under the influence, that he and two of his C3-owning friends drove them solely because their juvenile styling attracted juveniles. Rest assured I left his employ within days of that revelation.)

Today is Monday, February 5, and it's so buttercupping cold outside that the custodian couldn't get our school's oil burner started. Consequently, my daughter is home for the day, playing on the rug in front of the fireplace. (Santa brought a wooden castle and a fine selection of medieval figurines, some of which are headed for the dungeon as we speak.) I'm at my desk in the music room, on the upwind side of the house—and the wind is murder. The west wall is cold. The north wall is cold. The floorboards are cold. But the air inside is warm as toast: I'm driving my Quad ESL speakers with a Joule Electra VZN-80 amplifier ($12,000) that isn't at all bashful about squandering a goodly amount of energy as heat. I can't think of a more delightful quality for an amp to have, at least on a day like this.

When audio designer Ken Shindo was a little boy, his father kept an enormous collection of 78rpm records in their home in Tokyo. During the final days of World War II, the Japanese authorities did their best to evacuate the city, but the elder Shindo was steadfast: He refused to leave, for fear that the records would be gone when he returned.

Manley Laboratories 175 monoblock power amplifier
Dick Olsher  |  Jun 30, 2009  |  First Published: Jan 30, 1995  | 
Neither its rather pedestrian name nor Manley Labs' own literature gives much of a clue as to the 175 monoblock's special pedigree. Where are the bands, the fanfare?! After all, the rolling-out of a 6L6–based high-power audiophile-grade tube amplifier definitely qualifies in my book as a momentous occasion. Deplorably, such happenings are rare indeed; the 6L6 has been unjustly neglected in high-end circles.

Manley Laboratories 250 Neo-Classic monoblock power amplifier
Paul Bolin  |  Sep 22, 2002  | 
There's something special about big tube amplifiers. No other audio component has such a primal appeal or can so quickly reduce grown (?) audiophiles to Homer Simpsons sighing, "Mmmmm...toooobs." EveAnna Manley, president of Manley Laboratories, understands the effect of high-powered tubes on the audiophile brain and shares the obsession. A Harley rider, mountain climber, and devoted music lover, she is one of the industry's most individualistic characters. You just have to appreciate a gal who ends each CES by blaring Rage Against the Machine at top volume.

Manley Labs 440 monoblock power amplifier

My reviews always begin in bizarre ways. Take David Manley...please! (Just kidding.) On the last day of Winter CES 1995, I found myself towing a tuckered-out JA to a few final rooms. (This was just after the January '95 David Manley/Dick Olsher tube-rolling brouhaha, footnote 1, regarding who should do what to whom, and with which particular tube.) So as we passed Manley's room, John Atkinson thought to stick his head in (the noose) and say hello.

Manley Labs Reference 240 monoblock power amplifier
Steven Stone  |  Sep 11, 2009  |  First Published: May 11, 1996  | 
In the name of journalistic ethics (footnote 1) I have to come clean. David Manley once gave me a gift. He presented me with a large, rather heavy, Russian-made watch at the 1995 Las Vegas WCES. A very manly watch: In fact, it said "Manley" right on the dial. The watch worked fine for about six months. Then it developed a very subjective approach to timekeeping. Time stood still, and my life wasn't even passing before my eyes. The watch has become a nice, albeit slightly ugly, mini–boat anchor; now my rubber ducky stays where I put it in my bathtub.

Manley Labs SE/PP 300B Monoblock power amplifier

This should have been a recipe for disaster.

It's no secret. David Manley has not been big on single-ended amplifiers. Not enough muscle. You're better off with push-pull. Still, with a growing market for single-ended stuff, I'm sure Manley saw a need to do something. Of all tube designers, Manley has always been among the most prolific.
