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!"

    What else is there?

    What else could one possibly need or use beside ears, a room, a chair, electricity, amp, source, cables, interconnects, stands (and speakers)?

    What accessories? What worthwhile accessories?

      How about the Totem Beaks? Maybe it might help...

        The Ikea Lak Speaker Stand

        I recently purchased a pair of the 65 cm stands to use with small 12" monitors like the HLP3.

        The construction is pretty bad: large screws on the top end of each leg that need to be screwed into the speaker base. That's it. From experience, i can tell you that making these legs stay truely perpindicular (90 deg.) to the base will be hard without modification, and that once installed, the legs will probably wobble somewhat. At the very least, the four legs need to be joined together (i.e. braced) at one and, still better, two locations.

        Has anyone confronted this situation since Alan made us aware of these price-savers?

        When it warms up over zero (and after i cut and gather up all the old biomass from my wildflower stalks and stems) , i am going out in my workshop and modify these stands, so they will be true and steady.

        They look quite nice.

          What you have there can not be a complete Ikea stand. You seem to have only the four legs of the stand. You are surely missing the thick veneered wooden top plate into which the four legs screw and onto which the speaker sits. The speakers are not in contact with the legs, nor would I suggest in my wildest moments of fantasy that you destroy a Harbeth cabinet by screwing into the cabinet underside directly!

          I have several of these stands: the machining of the legs and the top is excellent and when the legs are twisted onto the top they are at exactly 90?. The whole construction is stable and very elegant. I have a pair of C7's at home on these at the moment in my study: nice and tall.

            I must be awful at expressing myself in writing.

            I have the base (top?) on which the speakers would stand and the 4 legs that screw into the base. But the legs need to be braced I think, because they just screw into the base unit, as you say. But you say, not so. OK. I'll give it a go.

            I certainly would not screw/hammer/saw/touch the speakers in an way. The bracing is just to kep the legs vertical and position.

            Is that clearer.

              There is absolutely no need for cross bracing. The P3 weighs about 5kg. Just now I lifted off one of my C7s and climbed onto the Lack stand. I weigh 83kg. Then I jumped on the stand. It is absolutely stable.

              The machining is very good: the legs are at exactly 90 degrees to the top plate.

                That sounds great

                Well, that certainly puts the lie to my judgement. But it's nice to hear. Did you really jump on them? Wow.

                  Yes, I really, truly did. I distracted my wife by sending her on a mission to make a cup of tea a) so she didn't have to observe the circus show and conclude that I'd finally flipped and b) just in case it did collapse in which case I would have blamed you. Or her. Or Ikea. Or the HUG. Or everyone - but me.

                    The 65 cm models? (It would have to be for the HLP3).

                    I haven't put them together, but it's hard to believe looking at the parts in the box (4 legs + speaker base). Therefore, I am overjoyed by the results from your professional testing methods.

                      Yes, I just measured them. 65cms from floor to the top of the top plate. Strong as an ox. They suit the C7 very well indeed as the top plate is just a cm. or two bigger.

                        Lack stands with M30s?

                        Hi Alan,

                        I just joined this group, having recently bought a pair of M30s. I am enjoying their sound very much, even without proper stands. (They are sitting on open-back chairs!)

                        Would the Lack stands work well with M30s? Does it matter that the top plate would be somewhat larger than the speaker's footprint?

                        Thanks,
                        Edward

                          Probably a little short for the M30s, but I think you will find them an improvement -- perhaps a vast improvement -- on the open-back chairs. When I moved my Harbeths from chairs to the Lack stands, I was shocked at the improvement. For the price, just do it. Regarding the top plate, postion the speakers so the front planes are flush with or even a little overhanging the top plates of the stands.

                          I have my HL5s on the Lack stands. By my calculations, the HL5s should be on stands of the same height as the Compact 7s (on the basis of tweeter location). I could maybe go 1-3 inches higher, but it's definitely in the right neighborhood.

                            IKEA Lack stands. IMPORTANT UPDATE Jan 2008

                            Today I visited the IKEA store in south London to investigate the comment made here recently that IKEA have changed the dimensions of the stand. It seem to be true. Originally, they sold this Lack product as a plant-pot stand, but they now seem to have redesigned it as a mini-table with a much increased top-plate. I have bought two for experimental use under Monitor 40.1.

                            The IKEA part number is now: 401.042.70. The top plate measures 55cm x 55cm and when assembled, the bottom of the speaker will sit 45cms above the floor (about 18 inches) - rather tall for M40.1. This larger top plate is now really too big for all but the M40/M40.1 and even so, is bigger than the speaker's footprint: it doesn't look great but will get you going.

                            I strongly suggest that you invest in proper, approved stands like the Skylan or Brooke's stand as shown at our CES room, Jan. 2008.

                              Stands for C7ES3

                              Hi Alan, I'm Massimo and write from Italy. I have bought finally a pair of C7ES3 and i have the problem of the right stands. I actually have a a pair of Epos ST12 (50 cm. and 5/6 kg.). What do you think about? Are too light? And the Skylan 4P20?
                              Thanks, Massimo
