In addition to the modular speakers, PAP has expanded its product line,... Read More »


AURALiC Sirius G2.1 and Aries G2.1


These days it seems like many high end manufacturers are building all in one digital front ends. What I mean by that is one box that consists of both the DAC and Streamer. On paper this approach makes a lot of sense. With the rise of Roon and HD digital music services, many audiophiles are... Read More »


iFi's Stellar Nova and SupaNova Power Cords


My last foray in the fiefdom of iFi focused on fixing a pair of power problems that plague too many audio setups: ground loops and DC offset. The diminutive GND Defender and DC Blocker elegantly address that annoying rattle and hum—and at the most un-audio-extortionate prices. As I mentioned in that review HERE, the two... Read More »


Rotel's RB 1582 MKII Amplifier and RC 1572 MKII Preamplifier


I was first introduced to Rotel products back in the mid 70s when I bought my first Rotel turntable from the Stereo Buff in Springfield, MO. I was a poor college student, and they had very affordable prices. I ran that table through a Yamaha integrated amp along with a Aiwa cassette player and Genesis... Read More »

AirStream - Optimized Wireless Router from Fidelizer


Photo courtesy New York School of T'ai Chi Chuan Sundays at noon I take Qigong class, a Chinese discipline of standing postures and slow movements. Translated, it means "energy work," and is related to T'ai Chi Chuan. The aim is to help you achieve relaxation. Sounds easy, right? That's what you think. By the time you... Read More »


Triangle Art M-100 Mono Amplifiers and L-200 Preamplifier


I first came across Triangle Art around 7 years ago while scrolling through a familiar webzine. It was fortuitous as I was getting back into vinyl after abandoning it decades ago, leaving behind my thoroughly thrashed Garrard that carried me valiantly through my childhood and teens. What caught my eye in that webzine's ad was... Read More »


The Vanatoo Transparent One Encore Powered Loudspeakers


How's your consumer confidence these days? Mine could be better. Seems like the more I buy, the less I'm satisfied. Higher price and lower quality is starting to become the rule rather than the exception. I especially take umbrage with products that feature a description that seduces you into thinking they're great, and then disappoint... Read More »


PS Audio Stellar PowerPlant 3


There was hum in my system! It was the dreaded 60 cycle hum. So was it caused by a faulty power supply, or a power transformer too close to a high gain amplifier? No, more likely the progenitor of this problem was electromagnetic coupling somewhere in the cabling. Experimentation narrowed my search for the source... Read More »


Circle Labs A200 Integrated Amplifier - Thank You


Gratitude, or the expression thereof, is a universal struggle today. There is a lot going on, and we all are a little on edge, are we not? Billy Joel described it right in 1989 when he said so eloquently: "We didn't start the fire." Music is a great way to break the firefighting that goes... Read More »


The Fono Acustica Armónico Speaker Cables and the Critic's Gaze


The Covid-19 pandemic turned the world topsy-turvy, devastating lives. Nothing is the same. We are beginning to turn right-side up, so to speak, but life must now be perceived through differently tinted glasses. Where we go from here—what comes next? One personal side effect for me was the suspension of my audio sessions for the... Read More »

WyWires Diamond and Platinum Cables


Before I start this review I want to make one thing clear, I love WyWires. To be clear the reason I love WyWires is because they have been the only cable brand that I have found that truly enhances my system without any drawbacks. They are not cheap, but the cables act more like components... Read More »


The Ayre QB-9 Twenty DAC Upgrade - A Premiere DAC at a Bargain Price


Ever notice that our passion for audio sometimes mimics affairs of the heart? For example, as you muddle through a series of infatuations, disappointments, and "upgrades," you may find yourself gravitating to "the one that got away." For me, it was the Ayre QB-9 Digital to Analog Converter in 2009. A siren of song spot... Read More »


The New Apartment Lounge: The Mola Mola Kula Integrated Amplifier (with Onboard DAC and Phono Stage) Reimagines Downsizing


All Creatures Great and Small As a mid-50s baby boomer, I face the daunting but simultaneously liberating task of deciding which of my possessions to keep and which to jettison. For most of my adult life, I have chosen smaller, carefully curated living spaces over "mcmansions," a preference more and more Americans have embraced, young and... Read More »


Poseidon Power Cord from Stage III Concepts


The first inkling something outrageous was approaching came abruptly with the email teasers. Soon a conversation ensued (or, more accurately, a monologue) with Brian Ackerman, the Stage III Concepts distributor and proprietor of Aaudio Imports, about a product so far beyond the pale—a power cord weighing 35 lbs, essentially equal to three individual Stage III...

Marantz NA6006 Network Audio Player


This is too much streaming player and not enough at the same time. It feels like something only a forty-something could love, which I am, and I do. I love that it's a very good DAC, especially since my Rega Apollo will likely be my last CD player; when it dies, I'll just wade into... Read More »
