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.

Gryphon Audio Designs Diablo 300 Integrated Amplifier-DAC

Written by: Hans Wetzel
Created: 01 September 2016

Reviewers' Choice“Have fun dancing with the Devil.”

It’s the sort of line a B-movie bad guy would growl. It’s not the sort of sign-off you expect to see at the end of an e-mail from the founder and CEO of a high-end audio manufacturer. Yet Flemming E. Rasmussen, of Gryphon Audio Designs, in Denmark, had written just that in confirmation of my receipt of his company’s Diablo 300 integrated amplifier. If it were any other manufacturer, I’d have rolled my eyes and moved on. But Gryphon’s creations are bold and unusual looking, and I’d waited a long time to review one. I chuckled. Nervously.

Constellation Audio Inspiration Stereo 1.0 Amplifier

Written by: Aron Garrecht
Created: 15 August 2016

Reviewers' ChoiceImmediately before putting fingers to keypad for this review, I spent a considerable amount of time reviewing Constellation Audio’s Inspiration Preamp 1.0 ($9900 USD). I began that review by touching on the company’s lineage, highlighting a few of the minds responsible for its products, and describing its three product tiers. The Inspiration series comprises Constellation’s least-expensive models, succeeded by the Performance series, and finally their flagship line, the Reference series. But while the Inspiration models are Constellation’s introductory products, they’re by no means budget, stripped-down, bare-bones offerings. In fact, if I had to pick one word to define the Inspirations -- and in particular the subject of this review, the Inspiration Stereo 1.0 amplifier -- it would be value.

Kharma Elegance dB9-S Loudspeakers

Written by: Jeff Fritz
Created: 01 August 2016

Kharma International, of the Netherlands, was launched in 1993. However, the audio career of company founder Charles van Oosterum actually began in 1982, with Oosterum Loudspeaker Systems (O.L.S.). It is an understatement to say that van Oosterum has deep experience in high-end audio -- he has many speaker designs to his credit, many of which I’ve heard at Munich’s High End over the last 15 years.

Ayre Acoustics AX-5 Twenty Integrated Amplifier

Written by: Uday Reddy
Created: 15 July 2016

Reviewers' ChoiceThe Ayre Acoustics AX-5 integrated amplifier, which I reviewed two years ago, was an ear-opening experience. At the time, I stated that “the AX-5 is not only, overall, the finest-sounding amp I’ve ever heard, it ranks as one of the finest components I’ve heard of any type.” The AX-5 featured a technology previously unused by Ayre, called the Diamond output stage, which has since been extended to Ayre’s top models, the R series.

Luxman EQ-500 Phono Stage

Reviewers' ChoiceA rush of lavender to the head

Recently, I was lying on my back in savasana (corpse pose), at the end of the 75-minute sweat fest also known as my Sunday hot-yoga class. As the teacher first placed a cool stone on my forehead, and then, on my face, an ice-cold, lavender-scented towel, I found myself drifting into a state of blissful relaxation. This was healing balm after a hectic work week, and as the relaxing sounds of sitar and tabla wafted into the room, I melted into dreamland.

fo.Q Modrate HEM-25 Pure Note Insulators

Written by: Garrett Hongo
Created: 15 June 2016

Tweaks are for kids, to adapt a phrase from a 1960s ad campaign for Trix breakfast cereal. In the world of audio, the phrase is true and not true. Newbies fall in love with tweaks, for which are claimed miraculous improvements at little cost. The allure of customizing a relatively humble system has an attraction similar to that of using a tighter suspension and nitrous oxide injection to soup up a stock compact car into a tuner.
