It's winter time. Want to know the best tweak for the season? Humidity. Get a humidifier and maintain about 35% RH at the equipment rack.

Guest review by Mattias Jung of HiFi Statement. In the past few years I had lost track of the Lindemann company and their audio products. This was despite the fact that I had only the finest memories of the products from Bavaria since the early days, and whenever I passed by a Lindemann demonstration at... Read More »

Plugging a pair of Audio Art SC-5 ePlus Cryo Treated Speaker Cables into your system is like renting a Sebring convertible for a spin down Pacific Coast Highway, top down, taking in the sun splashed vistas and ocean air; they won't break the bank as they open up new sensory pleasures in your listening experience....

One example is the VPI Prime Scout turntable I use in my reference system, and another is the Audio Art Statement e2Plus power cable that, like the Scout, competes... Read More »

The Magneplanar LRS with stock stands attached 1973: William Michael Albert Broad sat at his desk at the Worthing High School for Boys with a particularly nasty scowl on his face. He'd just been handed his report card for the term, on which his chemistry teacher had scrawled the word "idle" across the unusually low... Read More »

"Is it live or is it Memorex?" If you're old enough to remember that ad for audio cassettes (hell, if you're old enough to remember audio cassettes) you also remember that nobody had trouble answering the question. I don't care how astounding your Nakamichi Dragon cassette player happened to be, nobody ever walked into your... Read More »

It's like sliding into the cockpit of a Formula One car. Everything about The Air screams first class—from its Furutech F150 M Nano Crystal Formula Rhodium plated connectors (HERE), laser cutout stainless steel tag affixed in Ferrari red leather, the thick, dual cord body in sky blue mesh, to its wooden cigar box like case....

I was quite excited when I received notice from Positive Feedback Editor Doc David that there was a Pass Labs XA25 Class A stereo amplifier available for me to write about for Positive Feedback (photo below). I had been mightily impressed with the 18 watt per channel (into 8 Ohms) First Watt SIT-3 single-ended amplifier... Read More »

Strange Relationships Cables are a source of much contention in our epic. So much so that some publications seem afraid to discuss them anymore. YouTubers will show you a coat hanger that somehow out-performs, or at least equals, Monster Cable. Devout subscribers to the esoteric could chew an ear for hours, pontificating that cables are...

Just looking at the SSCPS, you can tell Louis Desjardins knows a thing or two about materials design. But don't get him started—unless you've got a sizable chunk of time. We'll rev him up a bit later. First, let's give the floor to the Sparta Super Capacitor Power Supply and let it speak for itself.... Read More »

It was around 5 year ago that I learned a valuable lesson; never discount the validity of an audio tweak even, if it does not seem to have any apparent scientific basis, without trying it out first. The component that helped me learn this lesson was the Akiko Audio Tuning Sticks. It was claimed that... Read More »

They say a lot of things about small packages. "Good things come in small packages." There is a certain wisdom in that statement. Of course it rarely has an applicability to Heavy Weight Boxing! The professional athlete that goes 6'8" and plays, basketball, football, soccer, or whatever rarely feels that they would be better off... Read More »

Three years ago, while visiting Acapella's showroom in Duisburg, I experienced that a Poseydon could bring you closer to the dynamics of a concert event than even the most demanding hi-fi enthusiast could have ever dreamed of. And, the acoustic transducer currently being there in demonstration is intended to narrow the gap between reality and... Read More »

In the beginning I was the tweakaholic. I spent much time fooling around with and writing about all manner of audio accessories, searching for the sonic Band-Aid that would repair my sound.
