HUG - here for all audio enthusiasts


"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!"

  • The real sound of some tweeters! Nature's way of demanding attention ...

    I made this recording last year of the annual return to nest of Great Tits (Parus major) to their nest above my front door. The tiny chicks have their parents dancing in non-stop attendance for two weeks or so as the chicks are insatiable.

    Last year I was ready to make a recording of the chicks in full song, just days before they took to the wing - which I missed every year and assume to be early in the morning.

    Playing this recording really makes the point that energy in what hi-fi listeners attribute to the tweeter band can be extremely fatiguing if not perfectly blended with that of the upper band of the bass/midrange driver. So here is what a clutch (perhaps four or five) of tiny tweeters sound like with accompanying spectral analysis.

    The sweet sound of nature?

    I've read that a baby's cry falls right into the frequency range at which human hearing is most sensitive, which is why we find it so annoying - it demands immediate attention (for good evolutionary reasons).

    I've read that the Super HL5 has a slight "dip" in its midrange response. Bearing in mind the ear's great sensitivity to midrange frequencies, could this dip be in part responsible for the SHL5's "sweet" sound?

        We have some of the most beautiful birds in the world down here, my fav. being the Rainbow Lorikeet, (Trichoglossus haematodus). When i mention this some people they go aghast. Beautiful and personable, not to mention highly intelligent as they may be, their oral outpours in the morning far outweigh their physical beauty to some. Maybe these lorikeets need some SHL5'ing.
