The Grado Labs GH4 in place at Chez Levi (photograph by Bob Levi) The GH4 is Grado's second foray into creating headphones using Norwegian pine, upping the ante and overall headphone performance quite nicely along the way. By my count, Grado has used two types of mahogany, maple, oak wood treated by a whiskey barrel... Read More »

Let's face it, AC line power is the bedrock of every audio system. Not only is this singularly common commodity a fundamentally important component, vital for powering all gear in a system, the quality of that AC power line happens to significantly influence the performance capability of every component in each HiFi rig. The bad... Read More »

The Unbearable Joy of Thinking Outside the Box Now that GTT Audio & Video head Bill Parish and I are finally back on friendly terms (heck, he even calls me on the phone occasionally to give me a hard time, and to ask when I plan on finishing the reviews I promised to write, if... Read More »

I enjoyed hearing ATC's 40A (then $12,999) speaker four years ago; enough so I was tempted to buy them (see HERE for the review). They had a fuller range than my reference, and the sound was a bit sweeter. However, my reference ATCs employ an "SL" (super linear) driver for midrange and lower frequencies, as... Read More »

I don't suppose I'm alone in admiring those who can really work with their hands. Years ago, while serving a semester-long sentence in woodshop, I envied my pals who could cut, glue, plane, and sand mundane articles like planters and bowls into magnificent works of craftsmanship. Not being able to do any of this, I... Read More »

With a firm desire for innovation and iterative design, Schiit are a company which have taken the world of high-end personal audio by storm one product at a time. Their latest creation comes in the form of the Ragnarok 2—an integrated amplifier that improves upon the original with its modular design, heatsink components, and a... Read More »

I am sometimes ashamed of how little we know about audio, how little we understand about it. We fly to the Moon, we are getting ready to fly to Mars, we have quite good knowledge of how the universe is changing and what its structure is, we have found thousands of planets that are similar...

Phono preamplifiers come in all shapes and sizes and with varying amounts of user adjustability and convenience. The ARC Ref 3 phono preamplifier is hands down the smartest phono section I have ever had the pleasure of using and listening to. At the bottom of the intelligence pecking order are phono preamplifiers that only have... Read More »

Prologue: A Berning Desire Many years ago, I purchased a boxy little bespoke headphone amp for my Sennheiser HD600's called a MicroZOTL. Built by a mysterious mid-Atlantic, not-so-mad audio scientist by the name of David Berning, the MicroZOTL was a mighty tiny wonder. I loved it so much I had physicist / audio manufacturer Berning...

I tend to jump into things blindly, especially when it comes to this hobby. Most of the amps, headphones, and speakers that I am interested in are not sold locally. Some of the best things in this hobby are made to order, and they often times don't have a 30 day trail. Needless to say,... Read More »

Dean Cacioppo shares his thoughts about the Backert Labs Rhumba Extreme 1.3 Preamplifier. Read, and learn.... Dr. David W. Robinson, Editor-in-Chief In my humble opinion, the two most under appreciated aspects of high-end audio are room acoustics / speaker placement and... Read More »

Keces Audio (stylized KECES) is a high end audio audio manufacturer based out of Taiwan. They curate several different components, mostly focused around power (both creation and conditioning), so this review will be in two parts. One for the BP-2400 Balanced Isolation Power Conditioner, and the other for the P8 Linear DC Power Supply (Dual... Read More »

Yes, V-TEE-I. That is not a typo. VTI is not from New Jersey; they don't make turntables (although they support them nicely); as far as I know, the initials stand for something other than Virgo Taurus Industries. Actually, I had never heard of them until recently, myself. I was mulling the prospect of replacing my... Read More »

In 2010, I declared, "If you're looking for a pair of standmount monitor speakers and you have about $1500 to spend, buy the Nola Boxers." The quality of sound at that price made the recommendation a cinch. Many other reviewers and audiophiles reacted with the same enthusiasm, so it's not a surprise that Nola continues... Read More »

The Unbearable Simplicity of Good Design At the start of the summer, I waxed enthusiastic about the arrival of a boatload of new goodies that have made listening to music here at Casa Jeffries an unalloyed pleasure (HERE). Amongst the newcomers, the spectacular Kubala-Sosna Sensation cable loom really stood out. In my preview, I praised... Read More »

I've bailed from the Hi-fi shows. The combination of expense plus the effort to produce a timely report (which could be intense) had become onerous. Of course, I miss the meet and greet, not to mention keeping up on trends and all the new gear. If my local New York show ever got out of... Read More »

Since Adrian Lebena reached out to me three years ago with the offer to review Sonore's first product, the microRendu, a Sonore streamer has been in my system ever since. The microRendu was amazing—especially when paired with Sonore's Signature Linear Power Supply. It took my streaming experience—which previously had been restricted to bandwidth-limited and feature-limited... Read More »

I have reviewed almost every Synergistic Research (SR) Power Cord over the last ten years. Each generation made a significant step forward in sound performance. In my opinion, each was a competitive, if not superior option at every price point. My last review included a full loom of the flagship Synergistic Research Galileo SX cable... Read More »
