HUG - here for all audio enthusiasts

INTRODUCTION- PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound, realisable by controlling the confounding variables between tthe microphone and the listeners' ears.

For example, the design of and interaction between the hifi amplifier and its speaker load can and potentially will alter the sound balance of what you hear. To reproduce the sounds captured by the recording microphones, as Harbeth speakers are designed to do, you would naturally select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

Identifying components for their system neutrality should, logically, start with the interpretation and analysis of their technical, objective performance, as any and every deviation from a measurably flat frequency response at any point along the serial chain from microphone to ear is very likely to cause the total system to have an audible sonic personality. That includes the contribution of the listening room itself.

HUG specialises in making complex technical matters simple to understand, aiding the identification of audio components likely to maintain a faithful relationship between the recorded sound and the sound you hear. With our heritage of natural sound, HUG cannot be really be expected to guide in the selection, approval, endorsement or even discussion of equipment that is intend to introduce a significantly personalised sound to the audio signal chain. For that you should do your own research and above all, make the effort to visit an Authorised Dealer and listen to your music at your loudness on your loudspeakers through the various electronics offered there. There is no on-line substitute for that time investment in a dealer's showroom.

If you desire to intentionally tune your system sound to your personal taste, please consider carefully how much you should rely upon the subjective opinions of strangers. Their hearing acuity and taste will be different to yours, as will be their motives and budget, their listening distance, listening loudness and listening room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you.

Alternatively, if faithfully reproducing the sound intended by the composer, score, conductor and musicians over your speakers is your audio dream, then understanding something of the issues likely to fulfill that objective is what this forum has been helping with since 2006. Welcome!"

  • Has modern society evolved to accept stereo playback as natural sound?

    Every noise that we hear originates from a single source. Almost all noise originates from a single source, we hear the sound with ONE pair of ears, and if I am not mistaken a pair of ears can help localizing the source of the sound better than a single ear. OTOH, the stereo playback consists of two speakers producing the same sound identically and perceived by our ears as sound originates from a single source. This is contrary to nature yet we accept them and associate two identical sound as one. In fact, our brains pick up the same sound FOUR times!

    So have we adapted to stereo sound to associate it with real sound or would a stranger from a world far away from civilization perceive stereo sound indistinguishable between real and recording?

    I am not sure if your question can be answered except to observe that human physiology cannot have adapted in 80 years.

    It might be interesting to compare "binaural" with "stereo", and read up on the early work of Alan Blumlein.

    Or just Google "Alan Blumlein"

    A great man, who did much for audio, TV and the BBC; and whose work on Radar restrained Hitler's U-Boats, and probably saved the British Isles from starvation and worse. It is a pity he is so little known.

      Just finished reading in Wikipedia about Alan Blumlein. I had heard of him (especially by two friends -recording engineers- who so many times referred to his mics), still had no idea what an important scientist he was, a kind of Reference Point for the world's electronics development. What a man! How sad he was lost, being only 38 years old, so young...

      Really thanks for this, I feel I want to find a book about his life, a biography, as far as I've been studying WW2 for 37 years now collecting everything about it... My father was a Spitfire Mk VbA pilot with the R.D.A.F.... what more?
      Thanks again,
      Thanos

        The Radio Programme referenced at the bottom of this page was excellent

        http://news.bbc.co.uk/1/hi/technology/7538152.stm

        I don't know if it may be accessed in the BBC archives.

        I knew about Blumlein and his Radar work, but I had not appreciated how crucial his work was.

        Within a couple of days of the RAF Bombers being fitted with his on-board Radar Donitz http://en.wikipedia.org/wiki/Karl_D%C3%B6nitz had confined the U-Boats to base. With Radar the bombers could see them underwater and pick them off.

          Hi Thanos, Focal Press has a book on him.

          'The Inventor Of Stereo: The Life & Works Of Alan Dower Blumlein'. by Robert Charles Alexander - ISBN 0-240-51628-1, Publ. Focal Press, 1999

          Since it will be 80 years next year of the concept, perhaps Harbeth will come out with "80 years of Stereo" editions of their speakers. some very exotic veneers (from forests with good management practices of course) , solid silver wiring and posts (gold plated), fancy brand name caps and resistors, Beryllium tweeter and of course nothing else than Radial, maybe titanium framed supergrilles, acoustically transparent silk cloth, solid 18K gold "Harbeth" badge on the front, im puking already but im sure there'll be sales. sorry got carried away there....

            Forget the bling. Just make them active. Replacing passive crossovers with line level analogue crossovers could take distortion down an order of magnitude, and let those radials display their strengths even more.

              This site on microphone technique may shed some light on our understanding of stereo

                After three days experimenting with Tracy Chapman's - Behind the wall, I am unable to say for sure if her voice sounded more natural with one speaker instead of two. Though I thought she sounded a bit thin with single speaker but I wouldn't be so sure to stand by it.

                  The stereo presentation would capture more of the ambience of the performance space than the summed mono.

                  That alone could account for the "bit thin" observation.
