HUG - here for all audio enthusiasts

Since its inception ten years ago, the Harbeth User Group's ambition has been to create a lasting knowledge archive. Knowledge is based on facts and observations. Knowledge is timeless. Knowledge is human independent and replicatable. However, we live in new world where thanks to social media, 'facts' have become flexible and personal. HUG operates in that real world.

HUG has two approaches to contributor's Posts. If you have, like us, a scientific mind and are curious about how the ear works, how it can lead us to make the right - and wrong - decisions, and about the technical ins and outs of audio equipment, how it's designed and what choices the designer makes, then the factual area of HUG is for you. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and can be easily understood and tried with negligible technical knowledge.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings sub-forum is you. If upon examination we think that Posts are better suited to one sub-forum than than the other, they will be redirected during Moderation, which is applied throughout the site.

Questions and Posts about, for example, 'does amplifier A sounds better than amplifier B' or 'which speaker stands or cables are best' are suitable for the Subjective Soundings area.

The Moderators' decision is final in all matters regarding what appears here. That said, very few Posts are rejected. HUG Moderation individually spell and layout checks Posts for clarity but due to the workload, Posts in the Subjective Soundings area, from Oct. 2016 will not be. We regret that but we are unable to accept Posts that present what we consider to be free advertising for products that Harbeth does not make.

That's it! Enjoy!

    (...) there is a spike of wide-band (up to about 10kHz) energy that follows the initial impulse about 1mS (one thousandth of a second) later. (...) With the bottom edge of the speaker flush with the speaker's lower lip - which common sense says is the correct position, and looks attractive too - there is a distinct reflection - see picture - but with the speaker pulled forward by about 25mm, reflection eliminated. (...) So - maybe we should bring our speakers just a fraction forward of the stand edge, or is this a degree of precision far beyond what we can hear?

    Resurrecting an old topic, did someone notice any audible differences bringing the speaker forward as mentioned? Most of the stands designed for Harbeths have top plates more or less equal to the base of the speakers, while many other manufacturers use top plates smaller than the base of the speakers, I wonder if it has something to do with this kind of reflections.
