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. Deviations from a flat frequency response at any point along the signal chain from microphone to ear is likely to give an audible sonic personality to the system at your ear; this includes the significant contribution of the listening room itself. To accurately reproduce the recorded sound as Harbeth speakers are designed to do, you would be best 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 will alter the sound balance of what you hear. This may or may not be what you wish to achieve, but any deviation from a flat response is a step away from a truly neutral system. HUG has extensively discussed amplifiers and the methods for seeking the most objectively neutral among a plethora of product choices.

HUG specialises in making complex technical matters simple to understand, getting at the repeatable facts in a post-truth environment where objectivity is increasingly ridiculed. With our heritage of natural sound and pragmatic design, HUG is not the best place to discuss non-Harbeth audio components selected, knowingly or not, to introduce a significantly personalised system 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. Our overall objective here is to empower readers to make the factually best procurement decisions in the interests of lifelike music at home.

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. Always keep in mind that without basic test equipment, subjective opinions will reign unchallenged. With test equipment, universal facts and truths are exposed.

If some of the science behind faithfully reproducing the sound intended by the composer, score, conductor and musicians over Harbeth speakers is your thing, this forum has been helping with that since 2006. If you just want to share your opinions and photos with others then the unrelated Harbeth Speakers Facebook page http://bit.ly/2FEgoAy may be for you. Either way, welcome to the world of Harbeth!"

  • What can you hear?

    This is a rather fun site for testing your hearing and your system.

    http://www.audiocheck.net/soundtests...ones_index.php

    The audiogram hearing test probably needs to be calibrated with the Decibel app or other spl measuring device.

    On the blind audio tests I found I was OK at 3dB, could detect +1dB but not -1dB. The latter all sounded flat to me.

    My SHL5+ seemed to do everything fine except the vertical listening test (http://www.audiocheck.net/audiotests_ledr.php), which only seemed to image upwards by about 1m.

    On this test http://www.audiocheck.net/audiotests_dynamiccheck.php I could just about hear 54dB below full scale (which was about 90dB), possibly the acid test that most systems are massively over-specified in terms of what we can actually hear.

    The sweep tone generator was useful, as I got a surprisingly level sounding sweep from 30z to 60hz, better than I expected, although the drop off sweeping from 20hz was very significant. Using the "mark" function, I found I could just hear above 11khz, but nothing above 12khz, so I no longer have to worry above that level.

    Part of my decision to buy Harbeth was to be able to listen to lower volume replay that was also satisfying, my new mantra might be (and slightly stolen from previous words of wisdom) 'your hearing is the worst it has ever been but the best it will ever be'..........listen to your favorite music today!

      Just a question in regards to Decibels?

      Are Decibels discrete units of measurement, there is no 1000 x's make a decibel for instance? The regular but as I am learning, the arbitary dB measurements of a frequency response curve are presented in 5dB measurements which would indicate to me our hearing refinement is not very fine at all, is that correct?

      Although a whisper and a whisper can vary greatly if our voices can do that why can't our ears?
