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!

  • Spare parts listed on ebay as 'used by Harbeth'

    From time to time we are aware of spare parts (usually tweeters) listed on ebay as 'used in Harbeth speakers' or 'similar to one used in Harbeth speakers'. An example is attached.

    Some sellers are blissfully unaware that there are many different versions of the same tweeter available - some for the hobby market, some for the pro market and yet others for the hifi market made according to custom specifications (like ours). Some of these differences are obvious (such as the colour of the diaphragm) but many differences are deep inside the unit, such as the voice coil height, its resistance and the strength of the magnet. We fully understand that if you are desperate for a spare part for a long discontinued model that providing the tweeter fits the cut-out you may well be satisfied for non-critical use. However, it is only possible to meet our original system specification if you use a spare part bought from Harbeth - when available.

    When we are aware* of a spare part listed on ebay uk, we check the listing for accuracy. In the example below we contacted the seller to advise him that Harbeth have not used that exact type of tweeter. We did not notice at that time that the seller lists it as a VIFA tweeter - in fact, the picture shows a SEAS unit. In this case, the seller has kindly amended the description but this is not always our experience: in particular some sellers of LS3/5a parts are extremely florid in their descriptions and confuse the numerous varieties of B110 bass units: despite our best effects to protect you, they will not amend their descriptions. It leaves us feeling powerless and dreading the inevitable buyers disappointment.
