Did you ever see an audio product that you thought you didn't need but once you looked into it you just had to have it? Such is the case with the iFi GO blu. As of late I have been rethinking my headphone/amp set up, and leaning more to adding an amp than a DAC.... Read More »

As in days of olde when men strode forth to slay dragons (or chase windmills), the modern-day audiophile is on a crusade. This villain appeared relatively recently, coincident with the world economy's tectonic shift to the Information Age. As many have observed, Radio Frequency Interference wasn't an issue for audiophiles circa 1970. Nowadays, it might... Read More »

In the realm of digital to analog converters there has been an ongoing trend of increasingly advanced circuitry, the addition of layer upon layer of "lifestyle" convenience features, and the promise of higher sound quality at increasingly lower prices. Certainly this sounds like the best of times for the cost conscious audiophile, but is that... Read More »

"Honey, I shrunk the headphone amplifier and DAC," is what the engineers at iFi probably told their marketing counterparts when they first showed them the prototype of the GO blu, and that is hardly an overstatement! When I received the GO blu in the mail, and unpacked the unit, I encountered a component that is... Read More »

So why all the Etc's? Because, while nominally an affordable MM/MC phono stage, the Parks Audio Puffin incorporates a flock of features and functions simply unavailable in phono stages commanding ten times the asking price ($489 to $639 depending on options). OK, not at any price. But for starters, the Puffin does do the phono... Read More »

On Mola Mola's website if you click on the Makua, the first thing you will notice is "Analog Design for a Digital Age" in bold under a picture of the Makua. It was this statement that first interested me in the Makua, and caused me to reach out to Mola Mola's US distributor for a... Read More »

One of those wall-warts came with the Fidelizer EtherStream network switch I use for music streaming. These little switch-mode devices have known issues. It is not good for music streaming; even worse, it spews contagion throughout the electric grid. With the ethernet switch on, my primary sources were degraded: the CD transport sounded worse. I...

The following review has been submitted by guest reviewer, Miguel Barrio. Boazu vs Ongaku: David or Goliath? Ever since I was a kid I have been fascinated by machines. When I was 6 years old I rewired my nightstand lamp. My mother freaked out thinking I would die from an electric shock. Sure enough, by... Read More »

I am happy to tell you about a little device that will do things you might never imagine possible. It is something that feeds my restless pursuit of perfect sound. You might simply call it a phono stage. But that would be like a fairy tale with only the, "They lived happily ever after" ending.... Read More »

I can't remember the exact date, around the late eighties, nor the exact model, but I used to own a Rotel integrated amp in my fledgling days of High-End audio. It served me well. Admittedly, back then my audio concerns were mostly of function over form. Did it have enough inputs? Does it have a... Read More »

The highlight bout begins with King Resolution dancing in his corner taunting Bishop Musicality across the ring, both egged on by PR guys with stakes in the outcome. The handicappers lay odds on the King. Why? Because resolution trumps all in the audiophile arena. These bouts occur regularly in my sound room. While I love... Read More »

Once upon a time the life of an audiophile was very simple. Take speaker cables, for example. At a meeting of The Audiophile Society in the 1980s, in front of a group of some 60 people, the featured guest presenter, a very prominent equipment modifier, proudly declared: "As far as I'm concerned, the only requirement...

Somewhere off shore, just west of Pillar Point Harbor in northern California, the 432 EVO High-End reference music server is riding a mammoth wave at Mavericks Beach. Championing the superiority of 432 Hz tuned music, via connection with the rhythms of Mother Earth, over today's 440 Hz standard, the surging swell is gaining momentum.  ... Read More »

In the 20th century the Japanese manufacturing sector gained recognition for the ability to improve products through a continuous refinement of the manufacturing process. In the early 1990s I attended Eastern Washington University as a business student and I was introduced to the concept of the Deming Cycle. This process was showcased by a profile... Read More »

Every once in a while, a piece of gear comes into the listening room that immediately makes its presence known as something special, something just a bit elevated from the other shiny boxes that make our hearts beat faster. Such was the case with arrival of the Parasound JC 5. However, in all fairness, I... Read More »

Chances are, you spend a lot of time either behind a desk, on a computer, or out and about without access to a quality home high fidelity stereo. Or, if you're like me this past season, your system is out of commission, tucked away in storage while renovations are being performed in your home. That's... Read More »
