TechDAS Air Force V turntable
Turntable Reviews
Michael Fremer  |  Aug 20, 2019  |  38 comments
Unless a truly budget-priced Air Force model is in the works, the TechDAS turntable lineup now seems complete: The recently introduced Air Force Zero ($450,000) is at the top, and the "affordable" Air Force V ($19,500) is at the bottom. The Air Force One, Two, and III turntables, all available in both standard and Premium versions, sit in the costly middle.

There's no Air Force IV because in East Asia that number is considered bad luck—which also explains why Japanese golfers shout "Six!" when someone hooks a shot into an adjacent fairway (joke alert).

CH Precision's massive, versatile, technologically sophisticated, 165 lb M1.1 power amplifier ($54,000 configured for stereo) can easily crush your foot if you're not careful when installing it. But the more important consideration is this: Can this cool gray techno-square sing and dance without stepping on its own feet?

Our conservative two-channel audio world doesn't easily accept change. Not that many years ago, even remote control was considered a sign of electronic moral decay certain to degrade sound quality. Today, home theater–like operating systems, with their fluorescent-screen hells and microprocessor-controlled functionality are commonplace, even in the highest of fi. Consumers accustomed to the convenience of audio/video processors now demand it on every price tier of two-channel hi-fi, though purists who think sound quality is commensurate with inconvenience can have that if they want it.

The digital ground seems to shift weekly. While firmware and software updates over the Internet somewhat slow the constant upheaval, when you do buy something, you just know that as soon as you plunk down your cash, something new will come along.

So, especially with preamplifiers, why not produce a design based on modules that the user can swap in and out, to custom-configure the preamp to that user's current needs while leaving room for later expansion? Why pay for six inputs' worth of stuff when at present you need only two? Upgrades? New features? No problem—swap out a module. Or, if a circuit in one module malfunctions, you can send only that module back for repairs, not the whole thing.

In 1959, in their musical revue At the Drop of a Hat, the British musical-comedy team of Flanders and Swann sang their "Song of Reproduction." It's not about sex. The song mocks audiophiles (you thought this was something recent?) for how we spend "all of that money to get the exact effect of an orchestra actually playing in their sitting room." Before launching into the song, Flanders quips, "Personally, I can't think of anything I should hate more than having an orchestra playing in my sitting room!"

Moon by Simaudio 888 monoblock power amplifier

Not everyone needs a power amplifier that can deliver 888W RMS into 8 ohms or 1776W into 4 ohms. You could say that no one needs one of these—or two, if you want to listen in stereo. Most household AC systems can't even provide enough current to deliver all that power. But Simaudio does build Moon 888 monoblocks, and people do buy them, whether or not they need an amp that weighs about 250 lb each and costs $118,888/pair.

EgglestonWorks Viginti loudspeaker

Viginti is Latin for twenty. It's also the name of a new loudspeaker from EgglestonWorks, to be produced in a limited edition of 250 pairs in celebration of the launch, 20 years ago, of the company's original Andra, on which the Viginti is based. The Viginti is a shapely and eye-pleasing 4' 2" tall, and weighs 255 lb—kind of heavy for its size.

Ypsilon Electronics Hyperion monoblock power amplifier

Michael Fremer  |  Mar 22, 2018  |  18 comments
Designers of hybrid amplifiers can use solid-state devices in an amp's input stage and tubes in its driver and output stages, as Music Reference's Roger Modjeski did in his RM-200 Mk.II—or they can use tubes in the input and transistors in the output, as Ypsilon Electronics' Demetris Baklavas prefers.

The advantage of solid-state at the input stage can be lower noise. In the RM-200 Mk.II's fully balanced design, carefully matched input devices result in high common-mode rejection and low-noise operation close to the levels achieved with the best input transformers. The RM-200 Mk.II's signal/noise ratio measured a healthy 95.4dB.

People often ask me how I listen to music when I travel. I play MP3s on my iPhone.

That answer always surprises, and sometimes disappoints: "You listen to MP3s?"

The response is moderately tempered when I add that I use good in-ear monitors (IEMs)—either Westone ES50s (ca $995) or Jerry Harvey Audio Laylas (ca $2725), both with eartips made from molds of my ear canals.

Brinkmann Audio Nyquist D/A processor

What? Johnny-come-lately turntable manufacturer Brinkmann Audio now makes a DAC? Are they desperate? What sampling rates does it support—162/3, 331/3, 45, and 78? I guess the vinyl resurgence is over! Why else would Brinkmann make a DAC?

If that's what you're thinking, consider that Helmut Brinkmann began designing, manufacturing, and marketing electronics well before he made the first of the turntables for which his company is best known in the US.
