The Arai Lab MT-1 Step-Up Transformer for Moving Coil Phonograph Cartridges


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 »

Lone Star Audio Fest 2017


Passion, that one word sums it all up and answers many questions. Why collectively spend decades evolving a simple table radio into a complex collection of boxes and wires? Passion, to advance the state-of-the-art in home music reproduction chasing an absolute ideal of fidelity. Why spend hundreds of hours designing a product line of HiFi... Read More »

LP Gear Vessel R3SV Cartridge


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 »


Charisma Reference Two Moving Coil Cartridge: A Honey of A Midrange


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 »

Cables from Audiomica Laboratory


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 »


Impressions: The GamuT Lobster Chair for Audiophiles


The GamuT Lobster Chair in the sweet spot at the PF listening room in River City. "And now," said Monty Python, "for something completely different!" When planning, setting up, or upgrading their listening rooms, audio folks don't usually spend too much time considering furniture. After all, loudspeakers. Electronics. Turntables. DSD. RTR tape. Racks. Cables. For... Read More »

A Second Visit to Distinctive Stereo


The coincidences were uncanny. Exactly a year ago to the date we first visited Distinctive Stereo. Plus two weekends before that we had gone to Mezzrow, a small jazz club in the West Village, to hear clarinetist Ken Peplowski. Guess where we were and who we saw two weekends before this year? The outing was... 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 »

The PS Audio Stellar Gain Cell DAC/Preamplifier: Sheer Audio Perfection!


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 »


Rogoz Audio Trio/BBS Anti-Vibration Rack


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...
