"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound from microphone to ear, achievable by recognising and controlling the numerous confounding variables that exist along the audio chain. The Harbeth designer's objective is to make loudspeakers that contribute little of themselves to the music passing through them.

Identifying system components for their sonic neutrality should logically proceed from the interpretation and analysis of their technical, objective performance, since deviations from a flat frequency response at any point along the signal chain from microphone to ear is likely to create an audible sonic personality in what you hear. That includes the contribution of the listening room itself. To accurately reproduce the recorded sound, as Harbeth speakers are designed to do, you would be advised to select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

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. This may or may not be what you wish to achieve, but on the face of it, any deviation from a flat response - and the frequency balance of tube amplifiers are usually influenced by their speaker load - is a step away from a truly neutral system. HUG has extensively discussed amplifiers and the methods for seeking the most objectively neutral amongst a plethora of available product choices.

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 and pragmatism, HUG cannot be expected to be a place to discuss the selection, approval or endorsement of non-Harbeth system elements selected, knowingly or not, to create a significantly personalised sound. 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 offerings there. There is really no on-line substitute for time invested in a dealer's showroom because 'tuning' your system to taste is such a highly personal matter.

Please consider carefully how much you should rely upon and be influenced by 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, loudness and room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you.

If faithfully reproducing the sound intended by the composer, score, conductor and musicians in your home and over Harbeth speakers is your audio dream, then understanding something of the issues likely to fulfill that intention is what this forum has been helping to do since 2006. Welcome!"

  • Amplifier Isolation Platform??

    I can understand isolation platforms for hi-fi gear with moving parts, but amplifiers??

    What possible effect could this have on an amplifier's job?

    {Moderator's comment: None perhaps?}

    The only reason I used to mount my power amplifier on a platform was to stop our cleaner hitting it with a Hoover! There was no audible difference with our without mount.

      800 quid would buy a very nice amplifier platform, a beautiful wooden shelf. You can bet your bottom $ that it makes no real difference (of course it doesn't) but I'm sure that to some it will tighten the bass, speed up transients and sweeten the treble. I recall years ago buying a small two level dedicated 'hifi' stand, the shelves were suspended on 4 little spikes, alas the shelves with time warped with the weight of the TT and amp, I was convinced that it was good for the sound to have that dedicated stand and yet it failed at even being just a stand.....

        Would possibly have a small effect with valve amps but not SS. Wouldn't be so bad if such items were realistically priced but they are usually obscene amounts for slabs of wood. The packaging often accounts for the majority of the price.
