INTRODUCTION - PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"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!"

  • Veneers - you decide

    We offer a range of veneers to compliment the colours and style of your living and listening environment. There are some who claim that veneers 'sounds different'. We can't say, but here are some recent contribution about this .....

    Don't leave us with the cliff hanger, Alan. Does Pernambuco really sound better than Willow?

    And does polishing with snake oil really make a difference over a supermarket aerosol?

      Beware of silicon polish!

      Labarum,

      Pledge, Mr. Sheen or any other domestic aerosol polishes that contain silicon are to be avoided - evil stuff!

      Dust with soft cloth at regular intervals to keep them clean, and preferably, keep them away from prolonged exposure to direct sunlight (to preserve the veneer) and cigarette smoke etc.

        Of course it was tongue in cheek. Isn't the official advice to use nothing?

          Darkening veneers

          A question for Mr. Shaw: I /believe/ I read something to the effect that the Cherry finish darkens over time. My SHL5s are about 8 months old and are pretty light in color. I'm wondering what, if any, color change I should expect and, if so, over what period of time. Thanks.

          {Moderators comment: yes, some veneers oxidise with time and exposure to light etc.. Cherry generally becomes a little more orange with time, especially during the first year or so.}

            Not questioning your knowledge, but why? I've used it for years on all my wooden furniture.

              Sticky surface build-up

              Pledge, and other aerosol polishes? They do not feed the wood behind a modern impervious varnish: they just make the surface sticky.

              Traditional wood finishes respond best to traditional polishes, because they do feed the wood.

                I remember once reading that a speaker veneered on both the internal and external faces sounded 'different' to one that had only been veneered on the outside face...

                  I'm a woodworker as well and don't use pledge, but I can't understand what you mean by "Traditional wood finished respond best to traditional polishes, because they do feed the wood." can you be a little more specific?

                    Well I don't mean that the wood is still living and in need of nutrition!

                    Look at the use of the term in these adverts:

                    http://www.phg-uk.com/product_list.php?id=235

                    Especially:

                    Beeswax Paste

                    A traditional wax that nourishes wood and gives an authentic finish to furniture.

                    - ideal for small surfaces and furniture

                    - suitable for soft and hardwoods

                    - gives off a gentle aroma of yester year

                    - feeds wood and protects against excessive dryness

                    - for use on absorbent woods such as unsealed pine and oak

                    - EN71 Approved – Safe for toys
                    A wood surface that has not been completely sealed with a modern varnish remains porous. It will dry out over time and be susceptible to domestic stains. Continued application of waxes and oils helps prevent this and maintains a good looking surface. The polish is said to "feed the wood".

                    Traditional treatments like neatsfoot oil are also said to "feed the leather" in saddles and other tackle.

                    {moderator's comment: as far as we know our veneer surfaces are *completely sealed*, not porous at all, in common with all other modern speaker finishes. So take care not to apply layer after layer of shiny, greasy wax onto what is a completely non-porous substrate.}

                      Veneer

                      upon inspection, the finish seems to be satin finish polyurethane, thus an occasional wipe with a damp cloth and dry cloth regularly as needed should be fine) but anything with silicone would be a bad thing, aerosols should be fine too I think. Beeswax would be good but not really nec as it can change the sheen of the cabinet to a glossy one (unless that is the intention to begin with as posted). Do remember that this is veneer and not solid wood that absorbs much. maybe someone can confirm the actual finish used for topcoat.

                        Silicone. What's not to Like?

                        Again though, I must ask why? The woodwork is sealed, so the wood feeding point is a moot one. Silicone polish just does what it says on the tin - gives it a shine and doesn't attract dust. What's so bad?

                          silicone reacts with the finish over time, it makes the finish hard and when it dries over time produces cracks... beeswax as advised is better but a dry rags is all that is needed. a damp one when you need to remove grime...

                              Indian Rosewood?

                              Would you say that the rosewood used for P3ESR's is "Indian Rosewood"?

                              Not sure if this should have been in another section, but it is regarding veneers....

                              {Moderator's comment: we have no way of knowing which country any veneer is from. We select a range of patterns and colours and that is what we expect to receive.}
