Synergistic Research Active Ground Block SE

By | April 10th, 2019|Categories: Positive Feedback|Tags: , , |

One of the many reasons why I love the audiophile hobby so much is that it always affords me so many avenues to learn something new and interesting. For example, take the need to “ground” all your audio components. On the surface, grounding may seem like a boring concept. However, if you dig beneath the surface, it is anything but.

Electrical theory 101, states that the wire that supplies power to our components has three conductors. The “hot” conductor supplies the current, the “neutral” conductor provides the current’s return path to the ground, and then you have the ground.… 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

iFi AC iPurifier – Helping Improve Your Playback Experience by Reducing AC Power Noise

By | March 30th, 2019|Categories: Positive Feedback|Tags: , , |

At my old place, I had a plethora of audio-related problems, not the least of which was with AC power. An early 80s house, it was reasonably well built, but almost everything in the home was contractor grade, and not everything employed the best construction practices. I first noticed I had an issue when my subwoofers would randomly start humming, often very loudly. It took a while to diagnose that I had a DC leakage problem (of undetermined origin), and the affordable solution was an Emotiva CMX-2 common mode filter.… Read the full article

Roger Skoff writes about possibly unexpected things that can affect the sound of your system.

Well more than half a century ago, when I was a kid, the teacher in my High School physics class did something I will never forget. Let me tell you about it. Maybe you’ll want to keep it in mind, too.

One day, as part of his regular lesson, the teacher (sorry, but after all these years, I simply don’t remember his name) brought out an electroscope—a device for indicating the presence and polarity of an electrical charge [https://www.merriam-webster.com/dictionary/electroscope]—and showed us how it worked by using it on one of the batteries kept on hand in the classroom for just such purposes.… 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
