Reimagining Net Neutrality: The Mola Mola Kaluga Class D Mono Power Amplifiers and Companion Makua Preamplifier (with onboard DAC and Phono Modules)


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 »


Linear Tube Audio's Microzotl Preamplifier and ZOTL40 Reference Amplifier


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...

ampsandsound Suolo Monos: An And Game Amplifier in a Boutique Package


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 »


Impressions:  Final Thoughts on the Merrill Audio Element 118


David W. Robinson:  a portrait by John Robinson The Merrill Audio Element 118. Why that name? Simple, says Merrill Wettasinghe, the designer:  "Element 118 is named after the newest element in the periodic table called Oganesson, which completes the 7th row of the periodic table. The name Element 118 reflects the newest in technologies in... Read More »


Audio Research 160M Amplifiers - My White Whale


Even after two plus decades of reviewing, there are a few major brands that have largely eluded me. Whether it's been a timing issue, system need, personal bias, (I'll get into that more later), or I just haven't been in proximity of the brand. For me, up till a couple years ago, one of those...

Toes in My Head, er Sand - MrSpeakers' Aeon Flow Headphones, Schiit Gungnir Multibit DAC, and Ampsandsound Kenzie Amplifier


This note reflects, essentially, my first toe in the water of a higher end headphone setup, at least as a reviewer. I've heard high end speaker systems for decades. My first "high end" headphone setup was sometime in the late 1970s, an unknown model of magical Stax "earspeakers." At the time I thought them better... Read More »


Bricasti Design M25 Power Amplifier


This is the real deal. Or at least that was the knee-jerk emotion that flooded in during the first few notes from the Bricasti Design M25 power amplifier (M25) as it first drove my loudspeakers. Sure; the M25 had drive, poise, a neutral tonality, and an impeccably tidy soundstage. But most well designed high-power amplifiers... Read More »

Ye Olde Editor in action at RMAF 2015 (photograph by Jeff Day) Three things for you… As AXPONA 2019 is looming next week, I have three items that I need to write about briefly before I hit that trail to Chicago. These will be short and to the point…not everything needs to be War and... Read More »


Impressions:  The HeadAmp Blue Hawaii Electrostatic Special Edition Headphone Amp & MrSpeakers VOCE Electrostatic Headphones


Yon Olde Editor (portrait by John Robinson) A prologue:  of memories, music, and dreams… To start:  An extended and quite famous passage from Proust. Just read it, it will do you good. Many years had elapsed during which nothing of Combray, save what was comprised in the theatre and the drama of my going to... Read More »


TriangleArt Ultimate TA-350M Monoblock Amplifiers


Tubes or Solid State? That question alone divides us audiophiles—at its most basic level it's telling a story about your preferences, as there is no doubt about the pros and cons of both technologies. I will say that solid state (Class D, especially) has come a long way, but there really is nothing more captivating... Read More »


Constellation Inspiration 1.0 Linestage and 1.0 Stereo Amplifier: The Definition of Value


The Constellation Audio Inspiration 1.0 Linestage and pair of 1.0 Stereo amplifiers, driving the GamuT Flagship Zodiac Loudspeakers. From the Beginning For a company that just recently celebrated only its 8th birthday, Constellation Audio has proven itself virtually unparalleled in both accomplishment and acceptance. My first take was at their 2010 CES introduction, where I... Read More »


Mytek Brooklyn DAC+ and Brooklyn Amplifier


I was recently introduced to Mytek, a company out of Brooklyn, NY that specializes in digital electronics. Not being known for being the go-to guy for digital I thought the opportunity to try something completely different was something I could not pass up. Suffice it to say right up front that I am glad that... Read More »


Experiences with Gryphon Audio


Mythical Sound from the Winged Lion. How many manufacturers offer fully designed turn-key systems? How many do it with the panache of Gryphon Audio of Denmark? The answer can fit on one hand if you were missing at least two fingers. My first encounter with Danish designer Fleming Rasmussen's Gryphon Audio came with the review... Read More »


Parasound A21+ Amplifier


Spoiler Alert Parasound has chosen to take a staple core product that has remained an exceptional value for over fifteen years, the Halo A21 amplifier, and re-spin it into the Halo A21+. Doing so has proved that extremely high performance-per-dollar is still possible today when a company leverages decades of experience, and is spearheaded by... Read More »


The CH Precision M1 goes to M1.1: An Improved Statement Amplifier


The old capacitors. A Parcel Arrives One day a box of gargantuan capacitors arrived—really heavy industrial cans measuring nearly 7" high and 3" in diameter. They were destined to replace the main caps in my CH Precision M1 monoblocks. This was the hardware component of the newly released M1.1 Amplifier mod. I had been informed... Read More »

You may remember the ZeroUnoDAC and the ZeroUno PLUS looking like a small, tubed power amp, which inspired me a lot. Now, CanEVER Audio has expanded its product portfolio through offering a real power amp – the... Read More »


McGary SA-1 Vacuum Tube Stereo Amplifier


Okay everyone! Time for the obvious disclosure! How could I not want to review an amplifier that emblazons my name right on the front of the amp in such fashion? Just ignore that Mc part. This is truly a Gary amp! I was a bit surprised when the unit showed up at my door as... Read More »


Impressions:  The Ayon Audio HA-3 SET Headphone Amplifier and the Focal Utopia Headphones


High-end headphones and Personal Fi. I've evaluated a goodly handful of 'phones and headphone amps over many years, with some excellent results. Some were large cost-no-object designs, built for home, listening room, or office use only; others were compact and portable, for the music lover on the go. (I do a fair amount of flying,...

From an Editor’s Notebook: Glances in the Rearview Mirror


Ye Olde Editor, late summer 2018:  a portrait by John Robinson A late-year glance backwards. Memory, music, people, associations… "No sooner had the warm liquid mixed with the crumbs touched my palate than a shudder ran through me and I stopped, intent upon the extraordinary thing that was happening to me. An exquisite pleasure had... Read More »
