HUG - here for all audio enthusiasts

At its inception ten years ago, the Harbeth User Group's ambition was to create a lasting knowledge archive. Knowledge is based on facts and observations. Knowledge is timeless, independent of the observer and can be replicated. However, we live in new world in which objective facts have become flexible, personal and debatable. HUG operates in that real world, and that has now been reflected in the structure of HUG.

HUG has two approaches to contributor's Posts. If you, like us, have a scientific mind and are curious about how the ear works, how it can lead us to make the right - and wrong - decisions, and about the technical ins and outs of audio equipment, how it's designed and what choices the designer makes, then the factual Science of Audio sub-forum area of HUG is your place. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and can be readily understood by non-experts and tried-out at home without deep technical knowledge.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings area is you. If upon examination we think that Posts are better suited to one sub-forum than than the other, they will be redirected during Moderation, which is applied throughout the site.

Questions and Posts about, for example, 'does amplifier A sounds better than amplifier B' or 'which speaker stands or cables are best' are suitable for the Subjective Soundings area. From Oct. 2016, Posts in the Subjective Soundings area will not be spell checked or adjusted for layout clarity. We regret that but we are unable to accept Posts that present what we consider to be free advertising for products that Harbeth does not make.

The Moderators' decision is final in all matters and Harbeth does not necessarily agree with the contents of any member contributions and has no control over external content.

That's it! Enjoy!

  • Rogue Audio amplifiers with Harbeth

    One of our two local dealers of Harbeth products in Montreal often demo them with Rogue Audio products. These are vacuum tubes amplifiers designs made in the USA. The first time I heard Harbeth, C7ES3 and SHL5, they were powered by a Rogue Audio Cronus integrated amplifier using EL34 tubes. The sound was superb! Do any other HUGers have some feed-back from that Rogue Audio and Harbeth combination?

    Hi Sebastien. I was wondering if you could tell me what 12ax7 and 12au7's you're running in your Rogue these days. I was thinking of rolling some Ei 12AX7 / ECC83's to start with. I've owned my Cronus Magnum for two years now and I've never rolled the original tubes. Any suggestions you could offer would be greatly appreciated. I hope this post finds you well and enjoying music.

      I had the immense pleasure of listening to the Zeus with a set of Penaudio monitors years ago. That experience still registers in my mind. Afraid I havent heard Rogue with Harbeth but can well imagine, a good match.

        Tubes for Rogue Audio Cronus

        Hi Don,

        Actually, I have an awesome 6211 from GE (1960, five stars, side getters) instead of my center 12AU7. But for that preamplification function, it has to be perfectly balance on his two triodes.

        My two others 12AU7 aren't changed yet and my two 12AX7 were replaced by some GE's 5751 (1960, 5 stars, triple mica, grey plates).

        For tube rolling with Rogue products, it is a good idea to contact directly Mark O'Brien, Rogue's owner. He is very helpfull. I remember that he suggested me to replace the 12AX7 with some Mullard, but GE's 5751 were is other choice.

          The Cronus Magnum is a great match. The amp doesn't do anything wrong to the music. It may not be the last word as far as detail is concerned but overall, it's very musical and easy to listen to.
