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!"

      Re: Skylan Stands for Harbeth Monitor 40s

      Hi Tom,

      Great post. I think Noel is sincerely interested in providing the best possible support for Harbeth speakers. However, you mentioned that you were using the little black rubber bumpers between your M40's and the Skylan stands. I have a customer with SHL5 speakers set up similarly in south Florida (humidity?). After his SHL5's were on the Skyan's for a couple of months he needed to remove them from the stands. The rubber bumper (neoprene?) was stuck to the bottom of the speaker. As a result it lifted the veneer of the cherry finish in one of the four spots where the speaker was sitting. My first though was that this must be unique. As a Harbeth dealer, I am routinely moving speakers and stands so I have never had such an experience. However, I did have a stack of six albums sitting on top of the some Skylan 24" stands for about a month. When I went to move the albums two of the bumpers stuck to the back of the bottom album cover damaging it. The other two did not cause any damage. I have come to the conclusion that the little black bumpers can be dangerous and choose not use them. This is not meant in any way to disparage Skyan stands or Noel. I think he makes a great product. It is only meant to caution you (and others) from thinking your speakers are safe resting on the little black rubber pads for a lengthy period of time.

        I have not had any problem with the pads on Skylan stands sticking to any of the Harbeth speakers. Perhaps it is related to your climate in Florida.

          Re: Veneer damage due to BlueTak (or similar)

          We have specifically mentioned in the User Guide that accompanies our speakers http://www.harbeth.co.uk/library/use...erguidance.pdf .... to repeat ...

          be VERY careful about using these materials as they will bond to the veneer which will de-laminate when you try and remove the speaker from the stand after some months. Hot conditions make this even more of a problem. The tell-tale signs of this are unmistakeable and obviously our Warranty does not cover this.

          I hestitate to say how much BlueTak you can use without risk of damage, but I would guess that it can't be more than about half a small pea size at each point of contact.

          I am aware of another material called WhiteTak which is non-greasy which may be a better choice but I have not tried it.

              Myron,

              I partnered my SHL5s with the three posted Sound Anchors, and I can't imagine the four posted version will not mate at least as well. I was very happy with the combination. I used some stick-on "bumpers" I picked up at the hardware store between the speakers and the stands and between the stands and the floor (mine were sitting on a tile floor just off the carpet). There is the view that metal stands can ring from energy transmitted from the speaker; I didn't notice this, but you can listen for it and if you have any sense of it, use more isolation between the speaker and stand.

              Congratulations on the SHL5s - a most wonderful speaker!

              Ned

                Sound Anchor stands for SHL5

                I used to have 21” 4-post Sound Anchors, Compact 7 ES2, and non-sticking Big Fat Black Dots by Herbie’s Audio as interface. With some RPG sound treatment, the sound staging was grand with excellent focus. Imagine going to a store and listening to the revered MBL111 in an MBL system, coming home, and feeling not one bit underwhelmed except for the bass weight. I already achieved the voluptuous sound staging so touted of SHL5.

                I now use 17.75” 4-post Sound Anchors with new SHL5 and Big Fat Black Dots. The music making ability is nothing less than marvelous. The expensive Sound Anchors do provide fine definitions. Unfortunately, one SHL5 bottom may not be perfectly level. After trying two pairs of stands, I concluded that one speaker had movement when the dots were at 4 corners. I had to settle for a triangular arrangement with felt pads over the two back posts to protect speaker veneer. My experience shows that toe-in may also play an important role. I thought initially 12 degree toe-in would increase image focus. On some CD’s (such as the 1st track on Closer Than They Appear by Sara K on Chesky), I found left and right plucked string instruments to come straight out of the speakers. I could readily localize the speakers. I reset toe-in to 8 degrees and did away with the anomaly without degradation of center image.

                I reckon SHL5 to be really lovely for all sorts of music. 50% more expensive Dynaudio Confidence C1’s also have pure human voice, but not close in bass definition/richness. The one model I may concede to outperformance and it better for the price is the equally laid back Sonus Faber Amati Anniversario for cool $27,000 USD. They are dynamic, equally life-like, and can remarkably disappear for floor standers. I have some curiosity about Still Point Resonance Dampers as a replacement for Herbie’s products. However, I am hesitant to take a leap of faith based on a “glorious” review for the prohibitive price. With some care in setup, your SHL5 and Sound Anchors can be truly outstanding.

                    M40 woofer discontinued?

                    Alan, I have heard rumours flying that the M40 is not being manufactured due to raw material for the woofer being unobtainable. Is this true?

                      Re: M40 woofer

                      The rumour is not quite correct. There is nothing unusual about the materials used in the woofer. The situation is actually this:

                      Those nice people at Vifa ceased production of the M40s woofer some time ago. It would have been considerate if they had deemed us important enough to ask if we would like to make a final buy. They didn't. We have some stocks which we have reserved mainly for M40s going into the BBC, so the domestic hifi version is in short supply at the moment.

                      Derek and I have designed a Harbeth-made 12" woofer that does the job, Derek having much more experience in 12" design from the ground up than I do. We have jointly agreed every step of the design which does not need to be RADIAL because it is only covering the very lowest frequencies, but does need a good stiff cone, which it has. Together we've prototyped five or six experimental generations of this unit with various combinations of cone/surround, magnet and voice coil and now we are extremely pleased with one particular set of parameters which we have settled upon. Soon we will release the new unit. From the outside you will have to look very closely to see the difference, this being a key decision on my design brief.

                      In fact, this unfortunate supply strangulation has ultimately done us a great favour.

                            Support points for M40s

                            Alan, I have my M40s sitting on stools the tops of which are 14 inches square. Using four 2 1/2 inch square blocks - one at each corner of the stool - means that the M40s are supported about one inch in from the front and backs of the cabinets and about 1 1/2 inches in from the sides of the cabinets. Do you view this is a problem? If so, I could construct something to support the speakers closer to their outside edges.

                            Thanks, Ned

                              Ned,

                              You are worrying far too much about this. Even I wouldn't be concerned to this level of detail and I can't pretend otherwise. The Yellow Pages makes a great support I've found, which means, in essence, anything goes!

                              Actually, by coincidence I've just spent the afternoon out in the sunshine with some cardboard tubes, a stethoscope, an oscillator a cheap speaker, a Slinky and a skipping rope just to refresh my memory about cabinet resonances/standing waves etc. etc. etc.. The theory is fine but fitting it precisely to the actuality is much more challenging - impossible in fact. Still, it was nice to get outside!

                                Thanks, Alan -

                                I'm reassured. The sound didn't concern me - as soon as I got them high enough off the floor, the M40s sang beautifully. I just wondered if there was any structural reason to have the weight supported closer to the strong vertical sides.
                                I won't worry, but will simply enjoy the music.
