HUG - here for all audio enthusiasts

Since its inception ten years ago, the Harbeth User Group's ambition has been to create a lasting knowledge archive. Knowledge is based on facts and observations. Knowledge is timeless. Knowledge is human independent and replicatable. However, we live in new world where thanks to social media, 'facts' have become flexible and personal. HUG operates in that real world.

HUG has two approaches to contributor's Posts. If you have, like us, a scientific mind and are curious about how the ear works, how it can lead us to make the right - and wrong - decisions, and about the technical ins and outs of audio equipment, how it's designed and what choices the designer makes, then the factual area of HUG is for you. The objective methods of comparing audio equipment under controlled conditions has been thoroughly examined here on HUG and elsewhere and can be easily understood and tried with negligible technical knowledge.

Alternatively, if you just like chatting about audio and subjectivity rules for you, then the Subjective Soundings sub-forum is you. 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.

The Moderators' decision is final in all matters regarding what appears here. That said, very few Posts are rejected. HUG Moderation individually spell and layout checks Posts for clarity but due to the workload, Posts in the Subjective Soundings area, from Oct. 2016 will not be. We regret that but we are unable to accept Posts that present what we consider to be free advertising for products that Harbeth does not make.

That's it! Enjoy!

    Monitor 40 upgrade?

    Dear Alan,

    Will M40.1 replace tri-wire with single-wire connector like C7ES3?

    Also please reconsider the possibility of offering existing M40 users upgrade service to M40.1, I really don't want to sell my beloved M40. But having learnt there is an improved version, especially with better home friendliness, it is really hard to resist the temptation of upgrade.

      My plan is to fit the M40.1 with one pair (red, black) of connectors. This is simple, and it allows me to design the network with complete confidence about the electrical load as seen by the amplifier.

      Upgrade: this really is not financially viable. Not only is there the logistics of returning the speakers to us (you will need fresh cartons, caps etc.) there is the risk of damage in transit, and the time and effort here to dissassemble and then reassemble. I guess that you'd end up with a bill for 75% of a new pair and the worry about transit damage to/from us.

      As for upgrade kits, our priority is to restrict the availability of the Harbeth-made drive units and to prevent those drivers removed from original M40 being used elsewhere.

        After your return from your well-deserved holidays, would you please be so kind and share that anecdote with us?

        Also, can the Monitor 40 domestic be ordered in grey paint? I like that colour and actually prefer to have a technical object like a loudspeaker look like an industrial item instead of a piece of furniture. But I don't like the transport handles that one sees on the pro version.

          Will: we have discussed in the office this morning your suggestion of using the hex grille from the C7ES3 on the M40.1. It's a very good idea and would simultaneously solve the issues of maximum acoustic transparency and protection from 'little fingers'.

          I've just made an experiment to see if I can fit the hex protective grille to a stock M40 tweeter: almost, but not quite. That means we will either have to tool-up to make a hex-grille specifically for the M40 (with potential for stock mix-up with the C7ES3's grille) or we have to redesign the M40 tweeter faceplate to take the C7ES3 grille. Either way, I feel much more comfortable with the tweeter protected.

          Thank you for an elegantly simple and eminently practicable solution.

            Alan, There's speculation/rumour that the new M40 will cost more in the USA than current pricing. Can you comment on this at this time?

                Here is a close-up of the hex grille. This photo is from the C7ES3. As you can see the grille is almost all air.

                  New Monitor 40 - suggested test music?

                  I'm now at the final stage of approving for production the new M40.1 (provisional name). I have played many different types of music from my collection - and I've run out of ideas. Perhaps you can suggest what music/tracks/artists you would use if you were auditioning the M40.1 at home or by appointment at a dealers. I would like to be sure that I've thought of everything!

                  My opinion thus far is that listening to music on these speakers at home is most alike inviting the musicians around for a private performance. But that always has been the uniqueness of the Monitor 40.

                    New Monitor 40 - suggested test music?

                    The album "Naked Songs" by Rickie Lee Jones is an exceptional live album in both fidelity and musical quality. The crowd noises are also very realistic and give you the sense that you are there.

                    • Re: New Monitor 40 - suggested test music?

                      I found the following 2 tracks exercise the M40 and benefit from the full size presentation. Both tracks are high quality recordings, well balanced not over emphasized in any way, yet they capture and release every zero and one of the performance (at least my CD player does) in great detail - but are not offensive. These are red book CDs (not SACD etc).

                      The M40s really blossom with these recordings (in my opinion). I have not heard the other tracks on these recordings. I am usually so happy listening to these two recordings I can stop there and enjoy the rest of the day fully satisfied.

                      Sample 1 – Full track is 8 plus min (8 well spent min) and includes soft delicate as well as raucous lively sections. The entire orchestra gets a chance to shine together and as individuals. The M40s present every instrument clearly. On my systems you sound like your not too far behind the conductor enjoying fully balanced mostly direct sound.
                      Sample 1- http://www.amazon.com/gp/music/wma-p...am_wma_001_003

                      CD 1 http://www.amazon.com/Smetana-Short-...7529568&sr=1-2


                      Sample 2 - Full track is over 7 min long min (7 well spent min I might add) and includes soft delicate and raucous lively sections. The entire orchestra gets a chance to shine together and as individuals and the M40s allow you to pick out ever instrument clearly. On my systems you sound like your not too far behind the conductor enjoying fully balanced mostly direct sound.
                      Sample 2 - http://www.amazon.com/gp/music/wma-p...070675-5778064

                      CD 2 http://www.amazon.com/Ports-Call-Hug...7529843&sr=1-1


                      These tracks (particularly Finlandia) often leave my guests, and me speechless. For some of us they touch something deeper inside than our ear drums. Your listening experience and preferences in music may be different of course.

                        Thank you for your suggestions. It led me to the idea of creating my own personal 'sample CD' by ripping tracks from my CD collection.

                        I had a tremendous shock when I played them back - new thread created ....

                        • Harbeth Monitor 40 installed at the British Library

                          Just found the following news. A job well done by Alan & Harbeth again! Alan, suggest to include more details how did British Library evaluate Harbeth in the coming newsletter.

                          http://www.enjoythemusic.com/news/

                          "The British Library, with over three million recordings, moved its sound archive technical services into a new premises earlier this year and chose Harbeth for their loudspeakers. The custom-designed studios and transfer channels are a core feature of the new building, with each of the studios is named after pioneers of audio engineering that include Alan Blumlein (inventor of stereo), Thomas Edison, and Alec Reeves (the man behind Pulse Code Modulation which led to the digital sound revolution). The full range of Harbeth's handmade professional series of loudspeakers has been deployed, from the diminutive Monitor 20s, the near-field Monitor 30s, and the top-of-the-range Monitor 40s. "We chose Harbeth", explains operations manager Nigel Bewley, "because we deliberately didn't want speakers which would 'flatter' the sound. It is vital, in the work we do, to hear the clicks, crackles and other artifacts of a recording." The new studio will be used for archiving of the nation's sound collections."

                          • M40.1: final measurements (outside)

                            A nice sunny Saturday afternoon - what better than to make some nearly final measurements of the prototype M40.1 outside to verify the in-room measurements and computer simulations.

                            To save the inconvenience (and danger!) of clambering up and down the step ladder with a hot soldering iron, the crossover has been wired out on extension cables and sits on the table. The reason for the side panels on the cabinet is simply because this is the grey pro cabinet that has been used (more immune to knocks and bumps ) and the metal handel cut-outs have been blocked-off.

                            Note: all acoustic measurements are made with the grille on since the frequency response is flattest - thanks to Harbeth's unique SuperGrille technology.

                            Minutes after this picture was taken, the master prototype M40.1 nearly toppled off the stand ..... I just managed to catch it. And guess what - as I was grappling with it above shoulder height and wondering exactly how I was going to safely get it to the ground .... the mobile phone in my pocket started to ring to tell me my youngest son David (19) was at the railway station awaiting collection. How one must suffer for ones art!

                            ------------------

                            PS. Since this session, I found a way to simplify the crossover by 6 components and to increase overall sensitivity by 1dB or so by restructuring the crossover section that drives the bass unit.

                            • Monitor 40 and Stands

                              What stands are members mounting their Monitor 40 speakers on?

                              In particular and in a domestic situation what; material, configuration and height of speaker stand is in use by their owners?

                              Thanks

                                For my M40s I'm using 24" wooden stools, purchased at Target (chain store) for $17 each. The top is 14 inches square, a bit smaller than the base of the M40s, but no problem They are stained with a cherry wood color, so they match the M40s cherry wood finish. They're made for sitting on, so they're adequately strong. And being wood, they don't ten to resonate as metal might unless damped. With some of Noel Nolan's (of Skylan Stands) 'isolators' between the spealers and stands ( putting them close to 25 inches from the floor ) - which I find an effective height in my room - there is little transmission of sound from the speakers to the stands. So, for an inexpensive solution to the stand question, these work well. That being said, if I wanted stands that fit the M40s perfectly and looked like they're made for the purpose, I would look into Noel Nolan's Skylan stands. They're plastic but substantial and can be more easily moved about than heavy metal stands. Many Harbeth owners use them, and from what I've read, are very happy with them (the Skylans).

                                Good luck with your M40s - absolutely wonderful speakers!
