Symposium Acoustics Osiris Stealth Ultimate Equipment Rack

Written by: Howard Kneller
Created: 15 February 2017

Selecting an audiophile equipment rack can be unnerving. Rack makers rarely agree on anything, and almost all assert that their chosen design is the best. Look, for example, at the bewildering number of construction materials used: aluminum, acrylic, carbon fiber, ceramics, glass, granite, steel, and untold numbers of woods, common and exotic, solid and composite -- to name just a few.

Focus Audio Liszt Concerto Mono Integrated Amplifiers

Written by: Jason Thorpe
Created: 01 February 2017

I reviewed the Focus Audio Liszt Sonata integrated amplifier in April 2013 on SoundStage! Hi-Fi. To say that I was enamored of it would be an understatement. And just in case anyone hadn’t got the message, I followed up that review with an article that stated just how well suited the Liszt Sonata was to my specific musical tastes.

Magico MPod Support System

Written by: Jeff Fritz
Created: 01 January 2017

I’ve never been into tweaks. The thought of spending hour after hour replacing the supports of components or speakers with this footer and that, then straining to hear a difference, sounds worse to me than sitting in a bare room watching paint dry. I just can’t bring myself to do it. Heck, it’s been years since I reviewed even a cable. I prefer the meat and potatoes of audio reviewing: amps, speakers, and a source component here and there. The only tweaking I do -- and I don’t really consider it tweaking in the tweakiest audiophile sense -- is to fine-tune the positions of speakers, and micro-optimize the acoustic properties of my listening space, the Music Vault. I’ve found that both can lead to clear improvements in sound.

Linear Tube Audio ZOTL40 Mk.II Stereo Amplifier

Written by: Vade Forrester
Created: 15 December 2016

In February 2014, when I reviewed the David Berning Company’s ZH-230 power amplifier for SoundStage! Ultra, I instantly fell in love with it. Its sound consigned to the scrap heap -- or at least to the closet -- every other amplifier I’d tried in my system. This tubed design eschewed the output transformers used in virtually every other tube amplifier in the world, and which are responsible for lots of sonic problems. Everyone who heard it agreed that the sound was just splendid, and its 30Wpc easily drove my sensitive horn speakers.

Synergistic Research PowerCell 12 UEF SE Power Conditioner

Written by: Howard Kneller
Created: 01 December 2016

Reviewers' ChoiceIn 2003, I asked a representative from Synergistic Research why, unlike many other cable manufacturers, the company didn’t make a power conditioner. The rep stated that, despite Synergistic’s many models of interconnect, speaker cable, and power cord, head designer Ted Denney had yet to discover a power-conditioning technology he thought worth developing. According to the rep, only when Denney had found something that he thought would move the field forward would he put the Synergistic name on it.

van den Hul Crimson Stradivarius Phono Cartridge

Written by: Tom Mathew
Created: 15 November 2016

Just before he left for college, my son turned me on to a TV show that’s become my new binge-watching passion. Netflix’s Chef’s Table is a visual and gustatory feast, and the first episode introduced me to the culinary talents of Massimo Bottura, chef of the three-Michelin-star Osteria Francescana, in Modena, Italy. On the short list of objects in my house that are getting or have gotten better with age are a 1989 bottle of Krug Champagne, my cast-iron frying pan, my wife’s red hair, and a bottle of Manodori -- Bottura’s meticulously crafted, perfectly aged balsamic vinegar. Drizzled over risotto, shaved Parmigiano-Reggiano cheese, arugula, or fresh-picked berries, Manodori’s complex, multilayered taste is a perfect example of how well certain things in life can age.

Devialet Expert 1000 Pro Mono DAC-Integrated Amplifiers

Written by: Jeff Fritz
Created: 01 November 2016

Reviewers' ChoiceAudiophiles can instantly tell the difference between a traditional high-end component and a “lifestyle” product. It’s either one or the other, and until recently, their paths did not intersect. In fact, the death knell for a new product’s credibility in the audiophile community was rung as soon as the word lifestyle appeared anywhere in its vicinity.

Audience adeptResponse aR6-TSSOX Power Conditioner

Written by: Garrett Hongo
Created: 15 October 2016

Reviewers' ChoiceWhat is the true foundation of a seriously good audio system? I’ve heard very knowing people say that speakers set the character of the sound. Others argue that the amplifier is the key, as its power range and operating characteristics might also determine everything else. But, to more than a few, the true heart of any audio system is the preamp. Finally, there are those who insist that it’s source equipment -- the turntable, tonearm, and cartridge, or the digital player and/or DAC -- that determines each of our stereophonic fates. Yet before any of these essential components can contribute anything to the audio chain, it’s the power we get from our wall outlets that drives all else. No matter the quality and prowess of our vaunted audio purchases, saith a happy few, we won’t be able to realize the full capabilities of any of them without clean, reliable electricity.

Audio Physic Avanti Loudspeakers

Written by: Roger Kanno
Created: 01 October 2016

Reviewers' ChoiceWhen the SoundStage! Network’s Editor-in-Chief, Jeff Fritz, asked if I’d be interested in reviewing a speaker from Audio Physic, I knew little about the German company other than that they’d been around for a while and had produced some highly regarded loudspeakers. I typically review more modestly priced speakers, primarily from North American manufacturers. And while I knew that Audio Physic was well established, I hadn’t known that they’ve been around long enough to have celebrated their 30th anniversary in 2015.

High Fidelity Cables CT-1 Ultimate Digital Link, Interconnects, Speaker Cables, and Power Cords

Written by: Vade Forrester
Created: 15 September 2016

Reviewers' ChoiceNearly every audio journalist I know hates to review cables. Aside from their being lazy buggers, there are some good reasons they feel that way: 1) cables sometimes require lengthy break-in, and manufacturers aren’t always helpful about specifying a break-in time; 2) the differences in sound between cables are sometimes minuscule; 3) cables can sound different from a reviewer’s reference cables without sounding better or worse; and 4) cables’ sound may be system-dependent. But occasionally, a set of cables comes along that sounds so different -- and, sometimes, better -- that we find ourselves coaxed into reviewing another set of cables.
