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!

  • Technical evaluation of loudspeaker cables - the facts

    From Douglas Self, a respected amplifier designer his articel from Electronics World, Oct. 1997. Interesting observations about lawnmower cable. Interesting conclusions about the late, lamented Woolworths mains cable. Now that really did sound good.

    Cable science

    Thanks for posting this Alan, it confirms my own views with genuine science.
    Douglas makes some interesting comments on amplifier instability being problematic or "cured" dependant on cable resistance and capacitance. I remember in the very early seventies a transistor "high end" amplifier going unstable in some cases but never considered at the time that it was down to how it was connected to the speaker. If I'd known that, we might have sold a few more instead of selling unconditionally stable amplifiers from Cambridgeshire!

    In my book, if equipment is fussy about what it's attached to, driven by or fed with then it's got a problem.

    It's a disappointment that 79 strand wasn't tested, as it was available and in common use in 1997.
