David W. Robinson photographing at Icicle Creek, Leavenworth, WA, during the great fires of 2012. (Photograph by Lila Ritsema; image processing by Robinson.) Headphones…dig it! The spring of 1970. Yeah, that's when it happened. That's when I bought my first pair of headphones. I needed them, since I had become very interested in reel-to-reel tape... Read More »

What does mastering mean? Read and listen for yourself! The way mastering is executed at MOFI caused a lot of excitement among audiophiles, and Analog, the magazine of the German Analogue Audio Association, made mastering the cover story. And here, one of the best mastering professionals, Christoph Stickel, has his say in an interview that... Read More »

While I was supremely enjoying the Audeze LCD-5 Headphones on my E.A.R. HP4 Tube Headphone Amplifier and the Manley Absolute Tube Headphone Amplifier, Audeze came up with the new Audeze MM-500 Headphones to review. They have a similar ergonomic feel and look, but are smaller and purposed quite differently. The LCD-5 is an assault on... Read More »

GS3000x Wooden Grado Headphones I want to make it clear that the now discontinued wood body Grado Statement Series 3000e was my favorite go-to headphones for musical enjoyment and monitoring recording sessions. Their dynamic punch, beautiful definition, and excellent imaging rang every bell in the steeple. Frankly, I was surprised to receive the new 3000x. I... Read More »

I have very little need for escapism. I live in a very peaceful area, surrounded by lakes, trees, and very little traffic. My listening room is in my basement, further isolated still. My marriage is a happy one, and we have no kids at home. Only the occasional visit from the parents, siblings, nieces, nephews,... Read More »

Sensitivity First, I measured the sensitivity of the Audeze CRBN, comparing it to the Stax 007. My headphone measurement instrument is the Mini DSP "Ears," which is far from a standard. However, using my ACO Pacific SPL calibrator, I was able to calibrate the Mini DSP for SPL at 1kHz within about a dB, I... Read More »

Crosszone is a specialized audio company, founded in 2016 in Japan by the Taiwanese company Asia Optical Inc., a manufacturer of lenses and optical systems. It is headed by Mr. Robert Lai, and the first product was the CS-1 headphones. We are testing its latest product, the CS-8A headphones. The headphone selection on the market... Read More »

It is a particular pleasure to introduce the latest person to join the Positive Feedback creative community. Bob Katz doesn't need much of an intro to audiophiles who follow those who are masters of mastering...and of recording, EQ, and delivering the recorded performances that we all treasure. No recordings, no audio, eh? His résumé is... Read More »

Cutting right to the chase! I hypothesize that the excellent performance of the LCD-4 was criticized by many for its excess weight, and that the design required a makeover. At the same time, the CRBN Electrostat was bubbling up in R&D and would set a new musical standard for any headphones at half the weight. Most... Read More »

David W. Robinson: a Portrait in Winter, 2020. (Photograph by John Robinson; image processing by David W. Robinson) Switching my attention briefly to high-end headphones, with three of them in my queue to write up… Headphones. I do love excellent headphones…always have. Since my high school days in Walnut Creek, CA, every opportunity I had... Read More »

My father once said to me that if you live long enough, you will see everything. He was right—at least in this case. After 60 years as an audiophile and music lover, the ultimate in electrostatic headphone technology has finally yielded what I believe to be the most musical and lifelike electrostatic headphones on the...

As a lifelong two-channel audio listener I had my doubts that I could appreciate listening to music through headphones. A good friend of mine extolls the benefits of the personal listening experience, but I never could come around to seeing his point of view. Sure, I have inexpensive ear buds and in ear monitors for... Read More »

Empire Ears is a family-owned In-Ear-Monitor (IEM) company based in Atlanta, Georgia, that, collectively, brings over thirty years of experience in acoustical engineering and product manufacturing. As I mentioned in a previous review, every audio equipment company's product has it unique voice—neutral, warm, reference, detailed, bright, vivid etc—and its form. The Empire Ears' voice is,...

...with comments on the Synergistic Research MiG SX Isolation Feet. This is a story long in the coming. Long, long, long. Ye Olde Editor in contemplative mode, Happy Valley, OR, 2017… (Photograph by John Robinson; image processing by David W. Robinson) By way of backstory… You see, I've been following Warwick Acoustics and its predecessor... Read More »

We review products across a relatively narrow band, a niche, if you will. And our niche is dichotomous, generally, in that it supposes that great transparency and superb musicality can coexist in the same piece of audio equipment—headgear. Our research has revealed that we are, indeed, in a quite narrow niche, as manufacturers, to date,... Read More »

I have become quite familiar with Meze Audio, born in the city of Baia Mare at Romania's northwestern border. Their flagship headphone, the Empyrean, was selected as an AudioKey Reviews Best Product of the Year for 2020, and its In-Ear-Monitor (IEM), the Rai Penta, is an AudioKey Reviews' favorite. And not just because of the... Read More »

That so much transparency—detail, macro/micro-dynamics—and music lies within these small and, relatively, inexpensive IEMs is, no doubt, a wondrous discovery. For more years than I'd like to recall, I have chased after the audiophile "Maltese Falcon" (The Maltese Falcon, John Huston, Warner Brothers,1941) only to be left wanting for what a given piece of equipment—speaker,...

This review of the Final Sonorous III represents, per my directive, bringing those products to light that continue to distinguish themselves brilliantly, despite a host of earlier, positive reviews. In this case, the Final Sonorous III made their debut in 2016, but I find that they are remarkably well suited to 2020! "Fun, fun, fun,... Read More »

The In-Ear-Monitor (IEM) company VISION EARS was founded by Marcel Schoenen, a former guitarist and singer for the band SUIDAKRA (folk-metal), and Amin Karimpour, a design and IEM enthusiast with an "exceptional love for detail1." The two met while working for a leading German IEM company. And it would be a shared vision—for quality, product... Read More »
