Nordost QPOINT Resonance Synchronizer

By | September 17th, 2019|Categories: Positive Feedback|Tags: , , |

I am sometimes ashamed of how little we know about audio, how little we understand about it. We fly to the Moon, we are getting ready to fly to Mars, we have quite good knowledge of how the universe is changing and what its structure is, we have found thousands of planets that are similar to the Earth and we have finally “seen” a black hole, but we still cannot comprehend what (often) negative or (sometimes) positive impact a little wire, a piece of wood or aluminum foil, etc., have on the sound of recordings.… Read the full article

As it seems, every music genre and each trend within it and, on the other hand, every national discography have their “rarities”—rare and special, often simply “cult” albums.

“A cult…. liked very much by a particular group of people.” Cambridge Dictionary

The word “cult” is a shortcut that points out to the timeless and exceptional status of what it refers to.… Read the full article

A Technique – Fine Tuning, Part 3

By | June 29th, 2019|Categories: Positive Feedback|Tags: |

Time for cables

Cables are one of the elements that constitute an audio system. It is neither more, nor less important than the remaining ones, but it is still approached with suspicion and from a distance by many engineers and music lovers. However, those who have already gone through this stage—St. Thomas’s stage—do not need to explain anything. This article is dedicated to them.

Microtuning consists in actions that aim to precisely set up, equip and arrange loudspeakers, electronics and cables.… Read the full article

FinkTeam Borg Loudspeakers

By | May 1st, 2019|Categories: Positive Feedback|Tags: , |

The enormous WM-4 FINKTEAM loudspeakers caused a lot of confusion among people during the High End 2018 exhibition  in Munich. Looking at them and not knowing what it was all about, it was hard to say why, however. They did look a little different than most loudspeakers at the exhibition, but they still seemed to be mainstream—these are stocky loudspeakers with D’Appolito arrangement—two midrange drivers and a tweeter, with a really large woofer below.

Only having looked at them closely, one could become suspicious of their “ordinariness.” It was then possible to see that the tweeter is an AMT Mundorf driver, the midrange drivers have flat membranes and they have been made in-house according to the FMWD (Flat Membrane Wide Dispersion) concept (do you remember the NXT technology?), while the woofer is an enormous 15-inch unit with a paper membrane and textile surround.… Read the full article

Wojtek Karolak and Adam Czerwiński, In a Sentimental Mood

Wojtek Karolak Adam Czerwiński In a Sentimental Mood

Wojtek Karolak & Adam Czerwiński, In a Sentimental Mood. 

The album In a Sentimental Mood by leading jazzmen Wojtek Karolak and Adam Czerwiński, is one of the best vinyl records of recent years—both when it comes to music and sound. The text below is about how it was recorded and released, as well as what it sounds like.

It is extremely easy to release a vinyl record nowadays. By a curious paradox, technological innovations have brought vinyl to the verge of extinction.… Read the full article

An Interview with Luis Fernandes of Finite Elemente

By | April 4th, 2019|Categories: Positive Feedback|Tags: , |

The Finite Elemente METHOD (FEM) is a numerical method for solving problems of engineering and mathematical physics. Typical problem areas of interest include structural analysisheat transferfluid flow, mass transport and electromagnetic potential. The analytical solution of these problems generally requires the solution to boundary value problems for partial differential equations

Wikipedia.org

Mr Luis Fernandes, the current CEO of the German company called Finite Elemente, adds that it is a numerical calculation method used in the field of mechanical engineering and it basically means the division of a body into several “finite elements” which are used for the calculation of mechanical stresses.… Read the full article

Finite Elemente Ceraball and Cerabase Classic Anti-vibration Feet

By | April 4th, 2019|Categories: Positive Feedback|Tags: , , |

This time we got for a review the anti-vibration feet of the German company Finite Elemente, Ceraball and Cerabase Classic models. This brand is one of the precursors among specialized firms fighting against unwanted vibrations, which with these products returns to the market after a few years absence. We published an interview with the current boss, Mr. Luis Fernandes, beginning of January. The test that you are reading is therefore the second part of this publication.

I have a soft spot for Finite Elemente products (the company uses lowercase letters for their name: ‘finite elemente’, but I will stick to the normative spelling: ‘Finite Elemente’).… Read the full article

Kuzma STABI R Turntable

By | March 19th, 2019|Categories: Positive Feedback|Tags: , |

The leitmotif of all turntables from the Slovenian company KUZMA is “less is better.” Have a look at its iconic, “tubular” Stabi S turntable, to understand what it means—it’s just two brass tubes with a platter and an outboard motor. Also tonearms designed by this brand, no less famous than turntables, look like a study of simplicity.

In fact, these are advanced, precise “measuring” systems, if I can say that. After all, in the turntables, a stylus constantly measures the geometry of the vinyl record’s groove and converts this spatial structure to the corresponding voltage.… Read the full article

Acoustic Revive RTP-4EU Absolute AC Power Strip

By | February 21st, 2019|Categories: Positive Feedback|Tags: , , |

A power strip is simply a “splitter” of the power supply—it goes in with a single cable, and it goes out via several outputs/sockets. Acoustic Revive in Europe offers one model, featuring four sockets. We would like to present you the latest version called the Absolute.

This is the first part of a two-part test. Later we will present also the Absolute power cable and an entire Absolute system with the power strip, power cable and two filters.

“To filter or not to filter?” I was stopped with this question for much longer then it would take to chose one of these two answers.… Read the full article
