Have Class-D amplifiers gotten a bad rap? Despite my colleague Guido Corona's enthusiastic review of Merrill Audio's Veritas amplifiers (HERE) some four years ago, the sound and performance of all Class-D amplifiers still tends to be lumped together and in the words of the immortal Rodney Dangerfield, "…don't get any respect." Is or isn't that... Read More »

Many of our readers will have read my earlier rave review of the Unique Innovation Technology (UIT) interconnects back in Positive Feedback Issue 92. With some 18 meters of UIT Interconnect included in my two systems, I can now further report on the extraordinary performance of this under-$1000 per meter  interconnect development for audiophiles and music lovers. I... Read More »

Reviewing Reviewing has been a boon to me. I enjoy audio and music more than I ever have because of it. While my time for listening is pinched by my life outside of audio, I enjoy a greater variety of music than ever. I've discovered the wonder underneath the horror of the distant shore of...

I am so excited about this amplifier I don't know where to start. First and foremost is its surprising performance. Secondly is the price. For something so small and inexpensive, it seems only natural that expectation bias rears its ugly head. But that would be doing anyone with even a passing interest for this amplifier... Read More »

Air Tight's Supreme and Opus Cartridges What's the Pecking Order? "That would make life very interesting, but wouldn't it be overkill?" I was in the middle of a Thales turntable review and had the TTT-Compact II table and Simplicity II tonearm on the floor mounted with my Air Tight PC-1s MC cartridge ($14,500, $9200, and...

One look at the Arai Lab MT-1 step-up transformer (SUT) and you'll know in a moment that it is a very serious, ultra-quality, audio product. The fit and finish are impressive and impeccable, yet what really stood out for me was the Arai MT-1's considerable size and weight—it wasn't that much smaller than one of... Read More »

Extravagantly made for A&K, the T1p is a modified German beyerdynamics Tesla Gen. 2 headphone that are hugely popular in Great Britain and the EU. The A&K T1p, which are Cartier-like beautiful and...

When the final rays of light faded from the horizon on what was widely perceived as the twilight of analog playback in this hobby, there was a tragic loss of cartridge manufacturers and their parts suppliers. In those days, the high point of cantilever technology had been realized, and the stylus assembly mass of cartridges... Read More »

I covered back in Issue 80 of Positive-Feedback an entirely new moving coil cartridge from Bernard Li and Charisma Audio in Canada. The $1495 Charisma MC-2 cartridge rapidly made itself at home and didn't embarrass itself in my reference system. Nor was there any doubt by the end of the review that the MC-2, "is... Read More »

The end is nigh. I've read the news and it sure looks bad. Hurricanes, forest fires, eclipses! Oh my! Oppression, discrimination, bigotry! Oh no! Chaos and bedlam are consuming the entire world. UV light waves are only the beginning. We have an inch of topsoil left.  And what about the irreversibly progressive depletion of the... Read More »

With its top-of-the-range models, Transrotor plays a prominent role internationally in the highest league of analogue playback. However, to date there hasn't been a cartridge matching the high-end turntables in the company's portfolio. The JR Tamino now has come to change this. Of course, the analogue specialists from the traditional region of the so-called Bergisches... Read More »

Up until the arrival of the Stellar Gain Cell DAC a couple of months ago, my home system—while capable of producing some very satisfying music—was basically a cluster fu©k, with a mish-mash of two  preamplifiers controlling all inputs. One for balanced (Luminous Audio Axiom II), a second one for single-ended (Acurus RL-11), and a constant... Read More »

The Rogoz Audio website shows no less than 23 anti-vibration rack models and that doesn't include the latest series. Some of them are versions of the same model, a wider one or featuring more shelves, but still, it's a large number. Mr. Janusz Rogoz's company, since 2010, when it was founded, has gone a long...

AVM Audio Video Manufaktur GmbH is a German company that has been around more than 30 years but has only recently made a significant push into the United States. They have a huge catalog of electronic components separated into three product lines. The Ovation series is their current top of the line brand. After living... Read More »

I was on the phone with Vladimir Lamm discussing delivery of his LL1.1 Signature Preamp when somehow we got onto the subject of foreign accents. MN: "I am intrigued by foreign languages. I like sounds. My office is like the United Nations, so I get the chance to be an equal-opportunity abuser." VL: "That is... Read More »

The Waldorf Astoria Hotel in New York has a slogan. "The improbable will be done right away. The impossible takes just a little longer." The Astell&Kern A&ultima SP1000 Series High-End Music Player (or Digital Audio Player – DAP) took just a little longer to develop, but the impossible has been achieved. This sonic and technical tour... Read More »

Last year I reviewed Fiio's M3 DAP, which broke the mold and set new standards for great-sounding, CD-quality, microscopically sized DAPs at the sub-$100 USD price point. But if you wanted a more full-featured unit—especially on a budget—you were basically out of luck, with the only real competition starting at about the $500 USD mark.... Read More »

The little preamplifier that could? KR Audio is the now relatively well known Czech amplifier brand that made its name on very big, and big sounding, tubes and tube amplifiers. Who, in the audiophile world, doesn't know the fearsome name of the Kronzilla, with its awe-inspiring KR T1610 output tubes. While these are no longer... Read More »

Image courtesy of Tweek Geek Power conditioners are an essential part of a high fidelity audio system. The reproduction of musical sounds in our homes begins with AC power. Unfortunately, AC power is susceptible to all manner of electrical contamination that impedes audio components from sounding their best. Even dedicated sound rooms with independent wiring...
