Furutech NCF Booster Cable Holder

Written by: Howard Kneller
Created: 15 April 2018

I’ve said it before: No matter what type of audiophile you are, Furutech probably makes a product you’ve lusted after. In addition to power distributors and filters, and finished interconnects, speaker cables, and power cords, they make DIY bulk cables and component parts, and accessories that include the stainless-steel and silver-plated FI-50 NCF power-cord connectors, the Destat III Static Charge Eliminator for LPs and CDs, the DF-2 LP Flattener, Nano liquid contact enhancer and PC-α (Alpha) cleaning solution for CDs, the SK-III Electrostatic brush for discs and A/V gear, and a variety of AC outlets, cover plates, and fuses.

Raidho Acoustics XT-5 Loudspeakers

Written by: Jeff Fritz
Created: 01 April 2018

Back in May 2012, I reviewed the Raidho C2.1, a smallish, three-driver, floorstanding loudspeaker from Denmark that retailed for $28,000 USD per pair. A lot has changed since then for the manufacturer of that speaker, Raidho Acoustics. The primary designer of the C2.1, Michael Børresen, has left the company to helm Aavik Acoustics along with his partner, Lars Kristensen. Aavik makes some very expensive amplifiers and a DAC-preamplifier.

Waversa Systems WDAC3 Mk.II Digital-to-Analog Converter

Written by: Vade Forrester
Created: 15 March 2018

Part of the fun of being an audio reviewer is to discover new gear unknown to the general public. Such a device is this DAC from Waversa Systems, a Korean manufacturer previously unknown to me. Their founder, CEO, and lead design engineer, Dr. Collin Shin, draws on 30 years’ experience in developing low-noise, jitter-canceling chips for precision medical and military applications, to design circuits that will allow the listener to be enveloped by digitally encoded music. In designing this version of the WDAC3, Shin was assisted by legendary American audio engineer and SoundStage! Network equipment-measurement engineer Bascom H. King.

Rethm Maarga Loudspeakers

Written by: Tom Mathew
Created: 01 March 2018

Reviewers' ChoiceRethm’s polymath founder, CEO, and designer, Jacob George, is based in Cochin, in southwest India. He brings to loudspeaker design a nontraditional vision informed by his love of wide-frequency-band, high-efficiency, single-driver speakers, vacuum tubes, his trainings as an architect and engineer, and a musician’s ear. His passions for audio and speaker design were driven by his pursuit of a type of sound reproduction that existed in his imagination: fast, coherent, highly detailed, yet nonfatiguing. The products of that pursuit have been steadily refined, and have culminated in the latest Rethm loudspeaker, the Maarga ($9750 USD per pair).

Audience Au24 SX powerChord Power Cord

Written by: Garrett Hongo
Created: 15 February 2018

Reviewers' ChoiceOver Thanksgiving and the ensuing week, I flew down from Oregon, where I live, to spend time at a retreat for artists (I write poetry) in northern California near the Bay Area. Because I also had friends to visit, I rented a car when I landed at the Norman Y. Mineta San José International Airport, splurging on a full-size vehicle: a silver Chevrolet Malibu sedan. It was big and stable, gave good mileage, and had lots of features. It got me around -- to Berkeley and Lafayette, to San Francisco and Santa Cruz. But it didn’t have savoir faire. It lacked that je ne sais quoi that aging guys like me crave on getaways from our humdrum lives.

McIntosh Laboratory MA9000 Integrated Amplifier-DAC

Written by: Jeff Fritz
Created: 01 February 2018

Reviewers' ChoiceIntegrated amplifiers have often been touted as space savers. Combining two components into one, the typical integrated amplifier also does away with a set of interconnects, and results in a smaller package than would be possible with separates. This saves not only on real estate, but on price as well. You’ve heard all this before.

Forget it.

VPI MW1 Cyclone Record-Cleaning Machine

Written by: Jason Thorpe
Created: 15 January 2018

Last year, at the Montréal Audio Fest, I did a solid for Mat Weisfeld, president of VPI Industries. Throughout that weekend I’d been in and out of various rooms that featured VPI turntables, and during those visits Weisfeld and I had struck up brief conversations. Close to the end of the show’s final day, as we discussed VPI’s MW-1 Cyclone record-cleaning machine, as I was picking his brain about the finer points of the Cyclone’s design, Weisfeld asked if I’d mind taking the display unit home with me. “We’ve got enough to transport back to the States -- it’d be a great help if you could look after this for us.”

Esoteric Grandioso G1 Master Clock Generator

Written by: Howard Kneller
Created: 01 January 2018

I received review samples of Esoteric’s Grandioso K1 SACD/CD player and DAC ($31,000 USD) and G1 master clock generator ($26,000) at the same time. Figuring that not everyone would plunk down $57,000 all at once, I first reviewed the Grandioso K1 alone. Now it’s the Grandioso G1’s turn.

Pro-Ject RPM 10 Carbon Turntable with 10cc Evolution Tonearm

Written by: Jason Thorpe
Created: 15 December 2017

Reviewers' ChoiceCall me shallow, but I believe that in order to fully perform its job, a turntable must look good. Turntables aren’t like other components. They require constant interaction, for setup, fine-tuning, and daily use. Speakers just sit there, lump-like, and CD players can eject a disc with a push of a button. And don’t get me started on preamplifiers -- in this remote-controlled age, you need never touch a preamp again, and many of them don’t even have knobs. But this inveterate knob twiddler enjoys interacting with his audio gear. I take inordinate and vaguely inappropriate sensual pleasure in gently rocking a tube from its socket and then -- gently, s-l-o-w-l-y -- pushing in its replacement.

Esoteric Grandioso K1 SACD/CD Player-DAC

Written by: Howard Kneller
Created: 01 December 2017

Reviewers' ChoiceIn February 2015, I reviewed Esoteric’s Grandioso P1 SACD/CD transport, D1 mono digital-to-analog converters, and G-01 master clock generator. At a total cost of $91,000 USD, these state-of-the-art components in five hefty cases of aircraft-grade aluminum are not for the faint of checkbook or rack space.
