I am a lucky person. Who gets to be an artist, an aspiring griot, and a Stereophile reporter? Who gets to stay at home in paint-smeared pajamas, draw pictures of teapots and barn owls . . . and then, on top of everything, gets paid to listen to music made by Henryk Szeryng, Eugene Hütz, and Winston Reedy? C'est moi!
I have groovy friends, too: other eccentric artists, scruffy musicians, recording and mastering engineers, beekeepers, authors and editors, art and junk collectors, tube wizards, turntable savants, DJs, Mensa-type amp designers, bat-shit-crazy poet-philosophers, and unrepentant hoarders.
Approximately 331/3 years after AudioQuest's first phono cartridge, the company announced two new USB D/A headphone amplifiers: the DragonFly Black ($99) and the DragonFly Red ($199). Both have circuits designed by the engineer responsible for the original DragonFlyGordon Rankin, of Wavelength Audioand both have the novel distinction of requiring considerably less operating power than their predecessors, so much less that the new DragonFlys can be used with iPhones, iPads, and various other mobile devices.
Simaudio saw disc-based digital audio in its rear-view mirror at least as far back as 2011, when it introduced the Moon Evolution 650D and 750Dtwo iterations of what it called a "digital-to-analog converter CD transport." These were actually multiple-input CD players, but Simaudio was evidently so eager to distance itself from the spinning disc that it went with a product category that, in spite of its cumbersome, run-on name, drew a clean line between the disc-reading and signal-processing functionswhile bestowing upon the former second-class citizenship.
I first spied the Ayre Codex two Januarys ago, at the 2015 Consumer Electronics Show, and its scrappy proletarian vibe sure made it look different from any other Ayre creation. On learning that its price would be well under $2000, I was immediately curious what Charley Hansen and his gangmakers of the $3450 QB-9DSD USB digital-to-analog converter, plus a few five-figure amps and preampscould create when cost is an object.
I was lying on a mattress on the floor of an empty apartment on Manhattan's Upper West Side. Not as grim as it soundsit's a nice apartment, and the mattress was new, and had just been deliveredbut it was hot (no air-conditioning), and my family and my furniture were still in my condo up in Maine, and I was lonely. I needed some cheering up. Which is how I rationalized the decision to buy an Explorer2, Meridian Audio's tiny, inexpensive ($299) digital-to-analog converter.
Researchers at MIT recently discovered a "music channel" in the human brain. These neural pathways respond to all kinds of musicand only to music. "A listener may relish the sampled genre or revile it," Natalie Angier wrote in the New York Times. "No matter. When a musical passage is played, a distinct set of neurons tucked inside a furrow of a listener's auditory cortex will fire in response"
Of all the products I've reviewed or auditioned, a select few jump out as "best buy" recommendations. Almost universally, such products are liked by a wide range of audiophiles, and seem to match well sonically to many systems. Moreover, these products all have outstanding value; they offer a higher level of musical performance than you'd expect from the price.
The night before I started to write this review, PBS began a five-part series on computers called "The Machine that Changed the World." The first episode described the development of the ENIAC (Electronic Numerical Integrator and Accumulator), the first electronic computer. The ENIAC used 18,000 vacuum tubes, had over 500,000 solder joints, required a room 30' by 50', had to be physically reprogrammed with patch cords to perform different tasks, and packed less computing power than today's $4.99 pocket calculator.
Like all men, I learned at an early age to resist the allure of a pretty face.
OkayI learned that I should try to resist the allure of a pretty face.
Okay, I confess: I have never been able to resist the allure of a pretty face. Which is why, when I first clapped eyes on the Mojo D/A headphone amplifier from English company Chord Electronics, at an event hosted by Manhattan retailer Stereo Exchange, I had to borrow a sample for review.
I don't know much about horses, but I've been given to understand that dead ones don't respond to even the severest beating. In light of that, I'll make only this brief statementEven with the best playback gear of my experience, I don't derive as much pleasure from CDs as I do from LPs.and move on to a simpler truth: Regardless of what I think, CD players are still a necessity for most music-loving audiophiles.
I eat bits for breakfast. Lunch is a simple bit-sized snack. And dinner is the analog to real food. This has been my routine these past four years as editor of AudioStream.com, where we digest all things computer audio.
In that time I've reviewed over 100 digital-to-analog converters, ranging in price from $60 to over $12,000. This adds up to roughly 150,000 words spilled on DACs. You'd think my pen would be running dryespecially if you feel, as some do, that all DACs sound pretty much the same. If that were the case, I could have written just one review, for that very first DAC, then cut and pasted it for all the rest. What was I thinking?
Apogee Electronics Corp. has been in business for 30 years, and I've always thought of them as one of the pro-audio companies responsible for moving digital in the right direction. They've made their mark in recording studios around the planet with digital-audio interfaces and master clocks that have long been considered some of the most technically and sonically advanced, and that were probably used in a high percentage of the recordings in your collection. So when I saw Apogee pop up at the consumer end of the market with a technically unique product, budget-priced at $295, it got my attention.
In 1995, as the compact disc enters its second decade of commercial reality, it's fair to say that the associated hardware has come of age, exorcising at last the digital gremlins of time-base jitter and quantization noise. Digital-processor maturation is particularly evident in the design of the all-critical D/A processor. The simplistic digital circuitry of yesterday has given way to considerable design sophistication that deals directly with jitter and low-level nonlinearities.
The EAD DSP-1000 III is housed in a 2.5" high, U-shaped chassis with a brushed-aluminum front panel. The cover is made of solid, 1/10"-thick steel with a nice "powder" finish, giving the unit an expensive feel. A pushbutton standby switch sitting below a green LED indicator sits at the panel's left. Even when set to Off, power is maintained for the decoder's circuits, but the digital inputs and analog outputs are muted. To the right, three pushbuttons allow selection of one of the three digital input sources (TosLink, 750 ohm coaxial, or glass optical interface). Like the EAD DSP-7000 unit reviewed by J. Gordon Holt and Steven Stone (Vol.18 Nos.1 & 5), the DSP-1000 accepts any of the three sampling rates: 32kHz, 44.1kHz, or 48kHz. Toward panel center is a lock light that illuminates when a digital data link is established. HDCD decoding occurs automatically whenever an HDCD disc is played, causing the front-panel HDCD indicator to light. No remote is available for this decoder.
Unless something is broken, the bits from your computer will be delivered to your DAC intact; the claim behind three new products I recently listened through is that each can reduce noise within the DACnoise that could otherwise corrupt the analog signal and thus make our music less musical. This notion is not based on audiophool woo-woo, but on the basic electronics of mixed-signal systems: Although its input is digital data, a DAC's output is subject to all the noise problems of analog circuits.
