Tannoy Prestige Canterbury Gold Reference speakers Review

Floorstanding Speakers | Speakers

Ed Momkus

A Brief History of the Tannoy Prestige Line It doesn’t go all the way back to the time that Chaucer wrote The Canterbury Tales, but Tannoy is an audio company with a long and illustrious history. In 1948 Ronald Rackham of Tannoy (which had already been in existence for 22 years) invented the dual-concentric speaker, […]

PrimaLuna DiaLogue Premium HP power amplifier Review

Amplification | Tube

Paul Mah

  International union–a confluence of four countries for the sake of high-end audio Question: What do you get when you have Dutch, Chinese, American and Italian joined together? Answer: Mighty good eating if I’m referring to international cuisine. But since I’m writing about food for the soul, the new PrimaLuna DiaLogue Premium HP power amplifier […]

Constantine Soo

VIP 15 Exclusively For My Friends Vinyl In Print from………… The MPS Oscar Peterson Solo Recordings EAN:4029759094784   My first exposure to real jazz (meaning, not “dance band music” which is thoroughly composed) was How Long Has This Been Going On?, a 1978 Pablo Sarah Vaughan release, produced by Norman Granz, and featuring an Oscar […]

A Special Report

Interview with Christian Thielemann

Classical | Commentaries | Music

Lawrence Lock

Interview with Christian Thielemann Date: November 13, 2014 Location: Semperoper, Dresden The year 2014 marked the 150th anniversary of the birth of Richard Strauss (1864-1949). In mid-November I traveled to the “Strauss city” Dresden to immerse myself in the fabled Semperoper’s presentations of some of the German composer’s most celebrated operas. The Semperoper serves the […]


Horning Eufrodite Ellipse PM 65 speakers Review

Floorstanding Speakers | Speakers

Kevin Fiske

Having made a British designed and made pair of horn speakers the subject of my first review for Dagogo, I subsequently attended the UK National Audio Show at Whittlebury Hall, just up the hill from the British Grand Prix circuit of Silverstone. Curious to discover other European manufacturers taking a horn-based approach I visited LW […]


Music First Audio Baby Reference preamplifier Review Followup


Jack Roberts

Just in August of 2014, Doug Schroeder wrote a three-page rave review of this passive, transformer-based line stage. At the California Audio Show one of the most popular rooms and one of my top five, maybe the top, was the one with Music First, TriangleART, and Audio Note UK. This room was set up by […]

TEO Audio Liquid Pre preamplifier Review


Doug Schroeder

How many manufacturers of audio products do you know announce on their website, “New shipping requirements… no longer requires HAZMAT shipping designation!” None, right? That’s about to change; Let me introduce you to TEO Audio, maker of the Liquid Preamp. You read that right – liquid preamp, complete with ingredients such as Gallium, Indium and […]


Pass Labs Xs 300 Dual Chassis mono amplifiers Review

Amplification | Mono Block | Solid State

Ed Momkus

This review is about the fabulously over-the-top Pass Labs Xs 300 monoblock amplifiers – although how can you even call them “monoblocks” when each channel comes in two hulking metal enclosures? Pass Labs calls them “Dual Chassis Monoblocks”, but that doesn’t come close to fully describing this 298-pound-per-side power plant. So, how did I get […]


Pass Labs XA30.8 class A stereo amplifier Review

Amplification | Solid State

Jack Roberts

  In my review of the First Watt SIT-1 mono-blocks, I said, “If you’ve been an audiophile as long as I have, Nelson Pass is probably nearly a legend to you. I remember in my early twenties drooling over the Threshold amps. In the mid 80s he designed the real bargain amp of the day, […]


KEF M500 Hi-Fi Headphones Review

Headphones | On Ear Headphones

Paul Mah

We have a winner! I won these headphones at a KEF drawing during the New York Audio Show, held recently at the Brooklyn Marriott hotel. KEF neither solicited nor was I obligated to review the M500, but since I have really enjoyed listening to them for the past few weeks I thought I would let […]

Tri-Art Audio Pebbles TA-1 Turntable Review

Analog Sources | Turn Tables

Jack Roberts

Some may think it’s odd for me to be reviewing such an inexpensive turntable. Last Christmas I was looking for a turntable for my 29-year-old daughter-in-law who wanted an inexpensive turntable for her Christmas present. After she got her turntable, I’ve had a lot of people her age looking for entry level tables. So, I […]


The Beatnik Remembers HP

Beatnik's Journey | The Columns

Jack Roberts

As we come to the end of 2014, to me the biggest story in the audio community this year is that “HP” is no longer with us. I’m not one who sees HP as the founder of “High-end Audio” but he surely brought my generation to understand a kind of sound our stereo systems could […]

Raven Audio Shadow Reference Preamplifier Review


Jack Roberts

Raven Audio is a new and unique company as far as I know in that the electronics are designed in Korea and built in Texas. Dave Thomson and SE Han are the men behind Raven Audio. SE Han designs all of the circuits for Raven Audio. Raven Audio builds all the products in the tiny […]

D’Agostino Master Audio Systems Momentum Integrated Amplifier Review

Amplification | Integrated Amplifiers | Solid State

Greg Petan

This had been a pretty sleepy summer. I spent more time with my two boys for which I am eternally grateful but I feel I have lost a bit of my edge in the process. Daddy brain they call it. The thought of getting clever and deep in the audio realm seemed a touch out […]

exaSound Audio Design e22 DAC Review

DACs | Digital Sources

Doug Schroeder

The exaSound Audio Design e22 is the company’s third generation USB DSD256 DAC with preamp compatibility for headphones and audio systems. Improvements over the previous e20 include a 82fs Femto-Master-Clock, a headphone amplifier twice as powerful, lowered noise and distortion levels, a 12V Trigger Output, USB 2.0 input, and heavy duty RCA connectors. In addition […]


Sonorus Audio ProximitySub Controller


Fred Crowder

A Unique Audiophile Learning Experience – What exactly is the Sonorus Audio ProximitySub Controller? The older I get, the more resistant I become to change. Sometimes it takes a collision with something that your belief system cannot explain to cause you to re-examine those beliefs. For me this was occasioned by my recent visit to the […]

Teac UD-501 USB D/A Converter Review

DACs | Digital Sources

Paul Mah

  More zeros and ones I have had the pleasure of auditioning and reviewing several good sounding digital-to-analog converters this year, ranging in price from a low of $189 (iFi-audio Nano iDSD, iFi-audio Micro iDAC, $299, iFi-audio Micro iTube/Pre-amplifier, $299) to a high of $1,790 (B.M.C. PureDAC). I can now include the $849 Teac UD-501 […]

Essence of Music CD Treatment Review

Audio Accessories | Disc Treatment

Jack Roberts

I met Dr. Robert Spence at the 2013 California Audio Show. He had come out with Rick Schultz of High Fidelity Cables. This was the first time I had heard of Essence of Music. The Essence of Music is a product designed to reduce laser read errors, caused by bi-refraction, and the jitter caused by […]

BMC PureVOX Speakers Review

Floorstanding Speakers | Speakers

Doug Schroeder

Having enjoyed a taste of the BMC Pureline products such as the PureDAC and PureUSB1 Cable, I was primed to accept an invitation from Brian Ackerman of Aaudio Imports, the North American distributor for BMC, to review the PureVOX speaker. He unabashedly made some claims of outstanding performance of this floor standing monitor speaker, and […]

MIT Cables Home Theater Series HTS1S speaker cable, HTS1XLR balanced interconnect

Cables | Interconnects | Speaker Cables

Constantine Soo

MIT Cables’ $37k Oracle V1.3HR speaker cables have been in my system for over a year, and I acclimated to its exceptionally dynamic and luxuriously refined musical presentation on day one. Currently, the MIT Cables in my system consists of the $26,999 Oracle Matrix Super HD 120 speaker cables, the $21,999 Oracle MA-X SHD XLR […]

Artisan Fidelity Garrard 301 Statement Review

Analog Sources | Turn Tables

Jack Roberts

Artisan Fidelity is the result of a 22-year pursuit by Christopher Thornton to find higher fidelity sound for the home. He says it has simply been a labor of love. On his website he lists his title as Designer / Artist and I think that is a fair description. His love of music and audio has […]


47 Labs 4735 Midnight Blue CD Player Review

Digital Sources | Disc Media Players

Jack Roberts

The Sakura Systems website provides the following technical description: “In conventional CD players, or CD transport~DAC combination, with multi-bit DAC chip, the original I²S signal is converted to S/PDIF format at the transport circuit, then converted back again to I²S at the receiver of the DAC section. For 4735 CD player, Junji Kimura created a […]

47 Labs Lens II Speaker Review

Bookshelf Speakers | Speakers

Jack Roberts

I find 47 Labs to be such an interesting company. At times I am tempted to get rid of all my ultra expensive and big gear and just listen to one of their little systems, as they are so musically satisfying. While I have always considered myself to be in KISS (KeepItSimpleStupid) high-end audio camp, […]

EnKlein David Interconnect and T-Rex Power Cord Review

Cables | Interconnects | Power Cables

Ray Seda

A couple of years ago, I was introduced to the world of Enklein. At the time, after many hours of evaluation and break-in, I concluded that, though not ideal in every respect, the EnKlein “Zephyr” and “Taurus Reference” were a combination of interconnect and cable that clearly yielded improvement in my reference system. As it […]

Floorstanding Speakers | Speakers

Ed Momkus

I’ve got to start this review with an apology. I’ve had the Sonus faber Venere 3.0s in my home in various locations now for over 5 months and should have completed this review three months ago. In fact, I was mostly done with the review back in May. However, one thing led to another, and […]
