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!"

    OK on iPad 2

    Seems to work well on an iPad 2.

      Test results so far

      Very many thanks to those of you who took the trouble to reply. Without feedback we're just talking to ourselves here.

      With one or two curious exceptions, it seems that we have a 'quick and dirty' video demo system that's extremely easy to create content with and replays across a wide platform. Yes, the slow video refresh rate means that sound slips out of sync but that's so common now that we seem to accept it. Also - and I think this is actually a good thing - there is a five minute per video time limit imposed by the authoring system and that encourages me to just have a bash at a subject rather than spend much time planning and editing. We'll see how it works out.

      I thought we might move the camera into the drive unit assembly area (Harbeth unusually designs and builds its own woofers: most others buy from a catalogue) and let you see what goes into drive unit assembly. I doesn't employ high-tech equipment, is very labour intensive, and above all needs total human attention to very small details.

      Thanks again.

        Hand assembled

        That would be interesting indeed. True hand-assembled-in-England drive units are rare these days.

            Seeing the assembly area would be fascinating

            That would be fascinating Alan! Really looking forward to seeing how Harbeth make the magic happen.

              Really interested by this A.S.
              Thanks for exploring these areas with us.

                More efforts to produce TechTalk videos

                The discussion about which-amp-which-speaker which has worn my typing fingers to mere stubs and reminds me that if I actually showed you, looking over my shoulder as I design, what precautions I take to ensure that the impedance load the speaker presents to the amp is benign, this may hopefully allay any needless anxiety. You say that some other speaker designers create loudspeakers that present a difficult load to their driving amplifier. As I don't read hifi magazines I have to take your word for it - but why audio equipment manufacturers would want to put avoidable financial hurdles between themselves and prospective customers I don't understand.

                So today, we internally discussed devoting more effort to the TechTalk video section. Are there any subjects which could be covered in no more than 5 minute bites that you'd like to see here? Suggestion list ....

                1) The difficulty of achieving a target (flat?) loudspeaker frequency response whilst offering an easy electrical load to the driving amplifier
                2) ....

                (Whilst you are thinking about this, here is an unrelated explanation video I recently made for Victoria, or personal fitness trainer, who is limbering-up to making a series of Harbeth exercise videos. She's gamely offered to do all the editing, and just needed a little help to get her going. These same desktop-recording facilities I'll use to make our new TechTalks - very quick and easy for us to use - see here.)

                  Difficult speaker load is a badge of honour?

                  I really don't believe that many speaker manufacturers give much of a thought to designing an easy load. In fact, some wear it like a badge when their speakers need massive, expensive amps to give of their best.

                  Bit like having an ASBO - it should be shameful but some treat it like an award !!!

                    SME's example

                    British turntable company, SME, have done that kind of video. You can find them on Youtube. I found them very interesting and helpful to understand the building of such beautiful turntables.
