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!"

    Buon Giorno, Fiore!

    The Anniversary Editions from Harbeth seem to be veiled in mystery. I own two of them: 25th Anniversary Compact 7 ES-2 and 30th Anniversary Monitor 30.

    From what I understand, and correct me if I'm wrong A.S. or Harbeth PR, the Anniversary Editions have higher quality internal wiring and the drivers are matched to higher standards. Or was this for the Rendevouz Editions? I wouldn't mind knowing the facts on this myself.As for the sound, having never heard the standard version of either of my speakers, I have no way of knowing if they sound better or not.

      I am curious about this as well, particularly as a poster a few days ago claimed to own a "special edition" of the P3ESR, which I had no idea existed. Mind you, I'm quite happy with my "standard" version, but it does beg the question as to what exactly makes the "anniversary" or other special editions different. If the difference is meaningful, shouldn't it be available in all speakers? And if it's not, why do it at all?

        As far as i know, there's no special edition of P3ESR. All P3ESR comes with OFC Internal wiring. Correct me if i am wrong here Alan.Anyway, i had a 25th Anniversary SHL-5, a standard SHL-5 & currently owns a 30th Anniversary SHL-5 that has OFC internal wiring. Any difference you might ask? Yes, subtle ones but still discernable. One thing i noticed about the SHL-5 from the 25th anniversary model right up to the current 30th anniversay ones is that there has been a slight change in the super tweeter. The super tweeter has undergone 2 subtle physical changes. Just take a closer look at the profile of the super tweeter & you'll see the physical differences. And that probably accounts for the fact that the most current SHL-5 sounds a tad more open & transparent than the initial SHL-5 in 2002. With regards to differences in standard wiring & OFC wiring, i did notice (i could be wrong here) that the OFC version seems to sound a tad more transparent & highly resolved though i did not have a chance to hear the 2 different versions side by side. All i know is that my current 30th anniversary SHL-5 with OFC internal wiring definitely sounds slightly more open, detailed & better resolved than the 2002 or 2005 versions that i had.

        Btw, i've not seen a standard version of C7-ES3 here in Singapore. From what i know, all C7-ES3 comes equipped with the OFC internal wiring. Unless the thread starter is referring to C7-ES2.

          The OFC wiring is not standard here in the UK. We pay a little extra for the OFC wiring. Maybe due to demand the OFC versions are almost standard issue in some of the export markets. Am just guessing....

            Sounds like a little clarification is in order. I was not aware of any option to pay a bit extra and get OFC wiring in my speakers. Had that option been available, and reasonably priced, I might have taken advantage of it. Would I hear any difference? Perhaps not (probably not, in fact), but I wouldn't be left to wonder if my speakers might have sounded better yet for a nominal cost.
