HUG - here for all audio enthusiasts

The Harbeth User Group is the primary channel for public communication with Harbeth's HQ. If you have a 'scientific mind' and are curious about how the ear works, how it can lead us to make the right - and wrong - audio equipment 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 should be accessible to non-experts and able to be tried-out at home without deep technical knowledge. From a design perspective, today's award winning Harbeths could not have been designed any other way.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings area is you. If you are quite set in your subjectivity, then HUG is likely to be a bit too fact based for you, as many of the contributors have maximised their pleasure in home music reproduction by allowing their head to rule their heart. 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 only, although HUG is really not the best place to have these sort of purely subjective airings.

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

That's it! Enjoy!

  • Mass-loading speaker stands and speaker / room interaction or my imagination?

    Does mass-loading speaker stands alter the loudspeaker / room interaction? The reason I ask is that I set my new M30.1s on Atacama 4-pillar s500 stands with no filling material in the stands. Room is 15' by 9' and speakers are away from walls firing down the length of the room. I was very happy with the sound. After a week, (on advice) I added mass to the stands. ( I won't say with what since I don't want to get dragged into a debate over whether brown rice sounds more "organic" than sand or cat litter!!).

    With no change to either speaker position or volume control on the amplifier I noticed what I can only describe (probably badly) as a mid-range "resonance" on the same music (both acoustic and electric) previously played. I wondered if it was a room-induced interaction. I went away for a few days over Easter and on returning played the same music again. The stands are still mass loaded and the resonance persists. I can obviously experiment with moving the speakers or emptying out the filling material but before I do I was just curious to know whether or not my imagination could be playing tricks on me.

    Skylan write-up

    I wrote up some impressions a while back on the effect the Skylan stands had on the sound from my Harbeths here:

      Stands and their sonics

      I've been hoping that Harbeth would chip in on this subject one day. Mass loading stands can make a huge difference. It would be great to have the physics behind this explained so that its bit such a shot in the dark!

      I had some bookshelf speakers (Von Schweikert - sorry if spelt wrong!) some years ago on atacama stands, they sounded like small boxes when stands sand filled, but sort of 'disappeared' when I tipped the sand out. My 40.1's with sand (skylan) in the stands sounded awesome when quiet but overloaded the room with bass, without sand they don't sound quite so 'tight' but they can now be turned up with most music without problems.

        Just a touch of damping

        I find it is usually best to apply minimal damping material. Just enough to do the job and no more.
