Coherence Systems Sorcer Apprentice and Vivid


I was passionate about music in my youth. I lived for Rock & Roll. I had a good voice and, like many young men in that era, I started learning guitar and piano. When it was time for me to head off to college I had some choices to make. Earn my living on music... Read More »


Serve Vinyl on Your Best China with the Korf HS-A02 Ceramic Headshell


I first heard about their ceramic headshell last year when I was updating my turntable setup with a vintage Micro Seiki BL-91 turntable and a GrooveMaster 3 tonearm. "Ceramics? Isn't that what they use in pottery and fine china?" I thought. Nevertheless, Jam Somasundram, a friend and turntable specialist, insisted I try Korf Audio's HS-A02... Read More »


Audiomods Series Six LM Tonearm


In the late 1980s, I was fortunate enough to obtain the dream job of many an audiophile. I worked part-time at an audio store while attending a local college. The Stereo Shoppe wasn't a high-end store, though we did carry several well-regarded lines. This was also an era when print magazines ruled; you could walk... Read More »


iFi Audio Zen Phono


The last product I reviewed from iFi was their GoBlue. It is a wireless intermediary between your source and headphones. It works great. That one was a keeper. It gets its fair amount of use from my Android phone to my system when the mood for the sounds of Bluetooth rears its homely little head... Read More »


Grado Labs Signature HP100 SE Headphones – a Brand New Direction for a Historic Manufacturer 


One hundred years ago Joseph Grado, founder of Grado Labs, was born. In 1953, he established the iconic Grado Labs producing extraordinary phono cartridges and dynamic headphones in Brooklyn, New York. The skilled manufacturing continues there today with even stronger creative energy from John Grado providing the leading Epoch 3 Phono Cartridge and the very... Read More »


The iFi Neo iDSD 2 DAC/Amp: Yeah, Yeah, Little GTO!


The iFi Neo iDSD 2 occupies a most intriguing spot in the UK firm's extensive roster of DACs and DAC/Amps. At $899, it is the first step down from the much praised $3249 iDSD Pro Signature. In fact, the two are the only items the iFi website lists as "Home Audio" above the ZEN range... Read More »


New! HiFi-Tuning Diamond Fuses


Audiophiles spend thousands for a 39" (1 meter) power cord, only to follow it with an inch of conductor that costs around $3 at a local hardware store. That power cord may be highly rated, but current flow and sound quality will be constrained by the cheap fuse element at its tip. Surely, we can... Read More »


The S-DUO Pro Ultrasonic Stylus Cleaner + Gauge and I-Brush from HumminGuru


I recently became aware of HumminGuru, a Hong Kong based company with a quite forward-looking perspective on the viability of vinyl. While reviewing their affordable and very effective ultrasonic record cleaning machines (HERE), I also discovered a couple of accessories that break new ground for LP spinners. As with their record cleaners, HumminGuru's only outlet... Read More »


The Goldring Ethos SE - a Ringer of an MC Phono Cartridge


The Goldring Ethos SE Moving Coil Cartridge sports a capital G on its body's front like the "S" on Superman's chest—or the G on the University of Georgia football helmet of Herschel Walker—to which I see a passing similarity.  Going into his first game in 1980, he was a fourth-string running back—unexceptional, merely fitting in...

The Invisible DAC: My Listening Impressions of the dCS Varèse System


The dCS Varèse DAC For some time now, I have enjoyed visiting my friend Scott Carpenter who owns Evolution Hi-Fi in the Buckhead section of Atlanta, Georgia. As my friends will tell you, I am a frequent visitor of hi-fi shops, and I have a deep passion for the latest technology. Fortunately, Scott is not... Read More »


Acoustical Systems Archon Improved MC Cartridge


I love reviewing phono cartridges. In my incredibly neutral Helius Omega Tonearm, for example, they dramatically reveal either error or truth, thin or full textures, and the recording or the performance. Michael Fremer and Bob Levi at the LAOC Audio Society Board dinner, 2024  (photograph and image processing by David W. Robinson) The Acoustical Systems... Read More »


Origin Live Agile tonearm


In the beginning of 2024, an old acquaintance came to visit. While we have known each other for quite a while, I am afraid I only know him by his nickname of "What If." Some days my friend What If drops by for an evening to chat, other times it becomes a weekend stay. Well,... Read More »


A Pippen of a Component - the Pass Labs X150.8 Stereo Amplifier


The Pass Labs X150.8 Stereo Amplifier, seen up front atop a 1/4" steel plate on A/V RoomService EVP Equipment Vibration Protectors. In the back to the left is one of my reference Usher Audio ML-802 Loudspeakers.  As a longtime Chicagoland resident and audio enthusiast, the Pass Labs X150.8 conjures Scottie Pippen's impact on the 1991-1998...

Music Hall Stealth Turntable


I threw everything but the kitchen sink at this relatively affordable Darth Vader-looking contraption in terms of upgrades. Not because it's bad, but rather, because it's very, very good. It sounds and feels more like a $2500 product than something priced at $1649, including cartridge. Could a few, well-chosen and easily installed swaps make it... Read More »


The Dan Clark Stealth Planar Headphones - A Sublime Upgrade to Your Headphone Experience!


Good headphones immerse you in an aural cocoon, delivering remarkable soundscapes that allow you to escape the noise and stress of daily life. Whether I was listening to Steely Dan tapes with their low-grade hiss on an AM/FM radio cassette player over Koss "Stereophones" back in 1979 at my college dorm room, or savoring a... Read More »


MoFi Electronics MasterPhono Phonostage


Before we explore the exceptional performance and remarkable value that the moderately priced Mobile Fidelity MasterPhono Phonostage represents, the historian in me wants to make sure you understand why it is so noteworthy. Since Mobile Fidelity's humble beginnings as an independently owned audiophile recording company by recording engineer Brad Miller in March of 1958, it... Read More »

Bob Katz at work wearing the Audeze CRBN 2 Headphones, a portrait. (Photograph by Mary Kent.) Introduction Today I'm reviewing two remarkable products, both of which represent a new audio paradigm and a veritable redefinition of the state of the art! I know, this is an old audio cliché, but in this case I think... Read More »


Euphony Audio's Stylus OS 4.0 (RC 24), in Combination with Mozzaik Upsampler, S.M.S.L.'s VMV D2R DAC, and a Peek at Exciting New Upcoming Euphony Hardware


Over a decade ago, the late John Sunier of Audiophile Audition called me with a hardware review offer for the original AURALiC Aries streamer. I was clueless as to what a streamer was or what it was supposed to do, John was unable to offer any explanation of its function to me, and I only... Read More »
