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!"

  • 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.
