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!"

  • Doing experiments - reporting results - influencing other people

    We have at Harbeth the advantage of inheriting the BBC legacy in loudspeaker design, thanks to our founder. The BBC were generous in publishing their research papers covering audio, including blue-sky thinking about microphones, loudspeakers and all between. Objectivism of the BBC-type is now out of fashion amongst consumers. Ironically, the familiar corporations that make consumer electronic goods (Sony, Samsung, Intel, Nokia etc.) are all ruthlessly science-based empires, because science and the scientific method is the key to competitive advantage.

    I encourage HUG members to conceive and construct practical experiments to test-out audio theories that they may have. Visitors interested in pragmatism do look to us to provide rational comments in a sea of subjectivism and confusion. But I caution about drawing half-baked or in erroneous conclusions. We owe it to ourselves to make an effort to marshal the facts and present them in a way all of our visitors can understand. There is absolutely no shame in reaching an inconclusive result but to bend the result to fit our preconceptions is not acceptable.

    Great experimenters conceived experiments anticipating the results leaving the mundane matters of actually performing the experiments to their junior assistants. The results confirm the hypothesis or they don't. Either way, the result is a step forward in understanding. But the key is to conceive the test to generate well differentiated, black or white results, not maybe/maybe not shades of grey. That needs very careful planning and construction of tests.

    So, here in the Harbeth User Group, a manufacturer's forum run by Harbeth UK and with a remit to improve the understanding of audio, if you are going to use this forum to explain a test that you've undertaken, you need to state ....
    1. The objective of the test
    2. why you elected to perform the test the way you did
    3. what variables you eliminated, what variable you didn't or couldn't
    4. what you anticipated would occur and what actually occurred
    5. ... how you explain any differences between what you expected and what actually happened

    If you have an idea you'd like to test out for yourself - great, you're now a scientist! You're welcome here! - but you don't know where to start, tell us here and we'll see if we can guide you. If your experiment is properly constructed, it should be possible for any member anywhere on earth to repeat it and arrive at similar results. And if it isn't, then the HUG is not the correct vehicle to write about it because it's not adding to long-term knowledge about audio. And it won't pass Moderation.

    Everything I know about audio I discovered for myself. The primary requirement is curiosity and an awareness of the potential for self-delusion. I was lucky to have the BBC influence to guide me. We consider that audio science is of importance and lasting value to society for the benefit of this and future generations of music lovers. Help us to promote reason and intellect.

    In September 2010 we specified HUG's Moderation Policy. As we enter 2011, our fifth year of HUG we will be actively applying our Moderation Policy. In 2006 we said:

    Before posting, please ask yourself:

    * Will my contribution be of direct interest in twenty years to a future researcher studying BBC monitor speaker design? Or is it off-topic?

    * Will my contribution add some factual knowledge or is it just a opinion? (Example: strongly recommending this or that amplifier, stand, cable without careful A-B testing)

    There are many other general chat forums to to discuss audio. There are so few that are accessible for ordinary folk and rational, logical, science based. We positively want to be in that category.

    Please also avoid posting close-up photos of logo stickers, serial numbers, limited-edition signatures or similar unless you blur or obscure them. Thanks.
