It was more than 40 years ago today, 16 years old and cruising in Mom’s ‘62 Biscayne. That 5 button radio would get quite a work-out. “I want to hold your hand”, “Please Please Me”, and the other 1963-65 Beatle’s songs were left on only after a search for the Stones, the Who or the […]

Having reviewed high-end audio equipment for four years and counting, with two of them as Dagogo’s publisher, I have come to appreciate the incredibly transitory nature of the high-end audio marketplace, and that the key to a manufacturer’s success lies much in the competency of its U.S. distributor. The amount of work a distributor has […]

I’ll take one… in black! Constantine warned me of this. Not this CD player, the Roksan Caspian M-Series 1. No, he warned me of the potential “irresistance” a great product under review could have. Take a look at my review of the Eastern Electric Minimax CD player and you’ll see that I have had quite […]

Madison and 75th Streets New York City Bang and Olufsen were introducing a few new products and having an event to coincide with their new catalog release. They brought in their CEO, Mr. Torben Ballegaard Sorensen, for a yummy cocktail reception. BeoSound 3 It was a wonderful New York evening and I had a great […]

          I once read an article in an audio magazine which described a debate between well-know audio reviewers and designers on the question of whether the front-end, the speakers or some other component was the most important factor in the music reproduction chain. I read it with great interest, wondering what […]

Foreword by Constantine Soo For the most part, advancements in the audio hobby are often brought about by revolutionary approaches developed by visionary engineers. Oftentimes, it takes new ideas and talents from the field of electrical and mechanical engineering to realize appreciable improvement in reproduced sound, and papers from these distinguished minds have been continuing […]

So Many DACS, So Little Time Over the years I have auditioned and owned a fair number of DACs and single-box CD players. Some upsampled, others did not; some had a tubed output, others solid state; some were moderately priced, others quite expensive, and still others were somewhere in between. While virtually all of them […]

This review addresses the Boelen-modified EAD Ovation Plus’ 2-channel audio performance. Boelen-Noble Electronics offered me the Ovation in its original form for a first audition, which was returned later to them for modification. This review addresses performances of the Ovation in these two periods. For background on Boelen Electronics, please see the Introduction section in […]

Prologue I had not reminisced over my earlier days in hi-fi since my encounter with Audio Note’s 300B designs. I used to subscribe to the high-power notion and disregarded tubes as maintenance-ridden and imprecise. To solid-state amplification designers, that remains a statement of absolute truth; but my priority developed since then to the point where […]

Foreword There are many forms and variations to being a music lover, and one of them certainly requires a good ear. Then, there are those orchestra conductors and players that, by the virtue of their career accomplishments, are the fiery declarations for being the purveyors of music. Of course, there are always other professions in […]

Listening to music is my therapy. At my home in Philly, with my wife and kids, sharing music is a joy. When I come home from work, the first thing I do is turn on the stereo and play an album (album not necessarily referring to vinyl). My wife is always interested in my choice […]

Foreword It started when I was in high school, and continues to this day. When friends describe me as a bass-lover, I often felt misunderstood. They must have reached such impression because of my constant critique of loudspeakers’ bass performance. I would like to think of myself as an audiophile with balanced views of what […]

About D200 Mk III Since the 70s, solid-state amplification designs have been relying on field-effect transistors to deliver power, and the emergence of the metal-oxide semiconductor field-effect transistors (MOSFET) in the early 80s ushered in the era of high-current power amplification. Recent advancements in photolithography process are revolutionizing the density of the MOSFET, condensing it […]
