"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!"

  • A rugged upgrade

    First of all, I would like to congratulate all those responsible for the creation of this space, as well as all other users.

    I finally got the upgrade I most wanted. I bought a Harbeth Super HL5 that came to give me the musicality, the detail and the wonderful Middle range that I wanted (and needed). Its been quite a pleasure to redescover my discs.

    But as not everything is perfect, I got the super tweeter (from the right column), crushed and deformed (tucked in and pinched). I was istracted momentarily and my little son, put a finger on him.
    Not usual on him, never did nothing like that, but it happened.


    I wanted to ask you if you knew where I could get a supertweeter replacementequal model, given that, I would not intend to buy the full pair of these corrent model now on sale (which is the SH5 Plus model)

    I already saw it on ebay, Amazon, etc. But I can not find it anywhere in Portugal.

    Thanks for the help and my best regards to all. It's a pleasure to belong to this group.

    Harbeth will supply the correct tweeter for your speaker and at a reasonable price. Don't be tempted to buy a unit which 'looks' similar.

    If there is a distributor in Portugal, they should be your first contact.

      You may also want to inquire if it is possible to buy (a pair of) the super-tweeter used in the 40th anniversary edition, since it has protection bars added over the front of the dome.
