HUG - here for all audio enthusiasts

INTRODUCTION- PLEASE READ FIRST TO UNDERSTAND THIS FORUM!

"This Harbeth User Group (HUG) is the Manufacturer's own managed forum dedicated to natural sound, realisable by controlling the confounding variables between tthe microphone and the listeners' ears.

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. To reproduce the sounds captured by the recording microphones, as Harbeth speakers are designed to do, you would naturally select system components (sources, electronics, cables and so on) that do not color the sound before it reaches the speakers.

Identifying components for their system neutrality should, logically, start with the interpretation and analysis of their technical, objective performance, as any and every deviation from a measurably flat frequency response at any point along the serial chain from microphone to ear is very likely to cause the total system to have an audible sonic personality. That includes the contribution of the listening room itself.

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, HUG cannot be really be expected to guide in the selection, approval, endorsement or even discussion of equipment that is intend to introduce a significantly personalised sound to the audio signal chain. 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 electronics offered there. There is no on-line substitute for that time investment in a dealer's showroom.

If you desire to intentionally tune your system sound to your personal taste, please consider carefully how much you should rely upon 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, listening loudness and listening room treatment, not necessarily leading to appropriate equipment selection and listening satisfaction for you.

Alternatively, if faithfully reproducing the sound intended by the composer, score, conductor and musicians over your speakers is your audio dream, then understanding something of the issues likely to fulfill that objective is what this forum has been helping with since 2006. Welcome!"

    Sounds like the age thing is against both of us...it seems only yesterday I would be looking forward to a couple of days of tweaking and adjusting, now it just seems like work. At least the prize is still the same.

      As for stands, i have both the slylan and the steel open framed something solid for my M.40.1'.... both work well but both are lacking compared to my old wood stands made by spendor for the S-100.

      I feel the skylan are not transmitting the energy from the top plate through the feet, due to their construction of hollow plastic. The top plate is to thin an light to absord and dissipate the vibrations.

      The something solid are lively and provide a better path for energy to flow and dissipate. They lack a bit of density to the timbres and the speakers do not sound tonaly as saturated as they sould and could.

      So i use my spendor stands again (heavy wood top plate with half a centimeter higher edges to allow the bottom of the speaker to vibrate freely, resting on two vertical wood plates, and a wood base plate similar to the top one) and it just sounds great.

      I would love Harbeth to make their own matching stands, like spendor did.

      As an aside, i have curtians behind the speakers as well, and they tend to deaden the sound, make it flat and lifeless. Everething's fine when the curtain are only used on a third or so of the speakers' back surface ... amazing difference really.

        Hi Haddock...thanks for the feedback.

        I too have curtains behind the M40's, they are 4' wide and I have them hung so that thay are angled to eliminate the 90 deg corner. I have found that "closing" the curtain so that I'm only eliminating the corner but exposing the back wall does make an audible difference, the sound being more open and a bit more exciting - but not as alluring!!

        I've continued to adjust placement to alleviate what I considered to be boomy bass...I have found a position for the M40's that is as near to perfect as I think I'll find. The biggest change was less toe in, the speakers are now resting so that I can see ~3" of the back corner from my listening position. I currently have the speakers sitting 15" from the floor (on stands), between 13" and 15" there seems to be no discernable difference...so I'm having custom stands built that will place the speakers 14" off the floor.

        The stands will be built from 1" MDF, they will be very "pedestal" in design where the center will be able to be filled with sand or kitty litter.

        I'm very surprised at the imaging and staging abilities of these speakers...they are as near to disappearing as any speaker I have heard. The bass is now full and tight, any previously perceived boomy-ness has been alleviated. It's the midrange that is most startling...I continue to be awe struck at the realism...vocals are "you're there" real. In the current orientation I find the highs a bit rolled off, the speakers are angled up just ever so slightly, but my aging ears are appreciative of this sound...so I'm very happy.

        The faceoff between my M40's and my friends M40.1's may never happen...after hearing my setup I find my friend not so enthusiastic to compare. I have listened to his M40.1's in his home, all fronted by Pass and Linn...perhaps it's the Luxman gear in my system, but I would easily give the edge to my system in overall musicality - and I think he would too!

        Hopefully the stands will be fabricated soon, once I finish them in black piano laquer I will definitely post some pics...the Eucalyptus looks so awesome against black laquer.

        I'll keep y'all in the loop!

        Rick.

          Hi Rick,

          It's good to hear that you have the "near to perfect" position for the 40's.
          Pls share with us some pictures of your current room and set-up.


          Thanks

            I will attempt to accomplish that this long weekend.

              Some pics!

              Here are some pics of my M40's in Eucalyptus...they do look good!

              The stands they presently sit on were originally made for my Dahlquist DQM-9's, they have never had the finish applied. On these stands the M40's sit 15" from the floor, the pair I'm having made will raise the speakers 14".

              I added a pic of my beloved Luxman PD-300 table with Grace G704 arm...oh what a sweet combo.

              If you note the current toe-in, I have the back of the speakers showing about 1.5"...I keep going back and forth between this location and 3" of the back of the speaker showing. In this current orientation I find that the image remains entirely between the speakers, but is rock solid...when I toe the speakers out more the image or stage widens beyond the outside of the speakers but is not as solid at locating instruments and singers.

              I'm really enjoying these speakers...I look forward to the return of my Luxman M-05 amp, it will be a good match with these beautiful speakers.

              Rick.

                    After 22 years of no other breed we have moved on from Bull Terriers...the energy level was just too much with our busy lives. Those pics are not one of our Bully's, but my forever loved and forever missed Rocky looked exactly like the one on the right.

                    We now have a Bull Mastiff...alot of dog, but lazy and laid back.

                        Hi sunshine,

                        The curtains work very well. The room was initially very bright with a complete absence of bass, after the installation of the curtains both problems were eliminated.

                        If you look closely you can see the curtains that are hung on the long walls just ahead of the speakers, there are also curtains hung at the opposite end of the room to eliminate the 90 deg corner, as well as a very heavy and long curtain over the single window in the room. Oh, and of course the curatin under the TV.

                        In a previous home I spent near to a small fortune on treatments, this time I went to Walmart and spent about one hundred dollars and accomplished the same thing.

                        Rick.

                          Definitely the way to accomplish sound treatment - nice, heavy, interlined curtains. Improves the sound and keeps the peace with the lady of the house !!!

                            Hi Rick,

                            Your listening room is nice and big. Really match well with the M40. Have you thought of covering the TV? May be you can put a foam type diffusor or a simple heavy bath towel. IMO, this will minimise front sound reflections and you will experience better depth. I've tried it and it works.

                              So the tweaking has come to an end...the final position of the M40's is near identical to that in the photo's added earlier, now I'm just spending hours getting acquainted with the big guys.

                              Although listening to heavy rock is not very frequent anymore, I did pull out an album I purchased many years ago titled Monsters of Rock. It's live music recorded in Great Britain, I pulled it out to listen to 2 songs perfomed by the Scorpions (Loving You Sunday Morning & Another Piece of Meat) and as has become routine, the M40's provided a previously unequalled listening pleasure.

                              I was always aware that Rudolph Schenker was a great rhythm quitarist, but the M40's separated the instruments to an extent that I could follow every note played by Rudolph...amazing.

                              Of greatest importance to me is that I am genuinely disaapointed each time I have to walk away from my system - I'm listening to music more now than I have in the last ten years. I even sneak down after dinner most evenings to listen to at least one side of an LP.

                              The spikes and mounts are now fabricated for my new stands, I'm awaiting the delivery of the 1" MDF, and soon after I should have my new stands ready for painting. They will be adjustable in height from just under 14" to just over 15".

                              Rick.
