HUG - here for all audio enthusiasts


"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!"

      Difference M40 to M401

      The main difference is that the bass driver is a new design for the M40.1 and this required a re-worked crossover, resulting in a cleaner, faster bass.

      There might also have been some other minor 'tweaks' to improve the sound.

          I already heard C7ES-3 and SHL5 (which I own) and both of them will give you that kind of sound. They are easy and pleasant to listen to. The listening fatigue is almost at zero. Sure, you can be tired some days and don't want to hear any noise, but Harbeth are great even at low volume.

            M401 - natural sound

            The M40.1 is a wonderful speaker, communicative, natural and very easy on the ear. If you possibly can, have a demonstration.

              Not a hint of fatigue - you can listen all day

              All Harbeths are naturally warm & sweet IMHO. You can literally sit through the whole day listening to them without a hint of fatigue.

              {Moderator's comment - as Alan has commented, zero listening fatigue is his Number One design requirement. A speaker that is fatiguing should not be on the market as it is useless for natural reproduction. Simple as that.}

                Sweet sound and power

                Difficult to answer this question as all models of Harbeth speakers sound warm and sweet and give a relaxing feel that is free from listening fatigue.

                I believe a more pertinent issue to consider is the M40 requires more current to come alive than the M40.1s. The new M40.1s will sound at home with flea to modestly powered amps if you listen at low to moderate volume levels. If listening levels are higher, a powerful amp would be necessary.

                  thanks for all replys!
                  seems 40.1 is more easy to drive, but there is on chance to compare them.

                  {Moderator's comment: please remember that the M40 (original model) was replaced by the M40.1 some time ago. Any M40 you can find will be old/used.}
