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!"

  • What setup (source and amplification) for testing speaker design

    Dear Alan,

    I see in the 30min video of you listening and tweaking crossover in a room. It looks like a computer source you are using which allows you to switch music type quickly and easily. Will you be able to share your setup in source and amplification ? I am keen to know what amps do you use on a regular basis in your testing of your speakers.

    Now that the (exhausting) relocation to The Old Barn (built around 1580) is complete, I can catch up on correspondence. Sorry for the delay.

    The first point is that I'm not listening for pleasure - I'm using music as a test signal which will tease out certain latent characteristics in the drive units, the crossover or the cabinet or the room. What typically happens is that after listening for many minutes to a new design something in the music will catch my subconscious attention. Once this is raised to my conscious attention then it is very convenient to have an armoury of music close at hand (on a computer play-out system) which can be used to explore the issue that I am now aware of.

    It's always surprised me that audiophile demonstrations can be single pieces or whole track or entire disc played in their entirety. I've always found that the first sips of wine gives a truer impression of the vintage than the second bottle. Surely human nature is such that with enough exposure to any stimuli senses are progressively dulled as I'm sure many have discovered the morning after the night before!

    Again the electronics that I use it are neither new nor expensive. As I said, I'm listening through the electronics to the speakers and providing the electronics remain constant (and I have mentioned before the importance of periodic servicing by qualified engineers) then there is no need for me to invest in "audiophile" gear. However, if I was listening to music for recreation then an appropriate investment in equipment, a music library, listening room preparation and above all time and peace of mind would be well rewarded.

    I would expect that I could continue designing loudspeakers on a desert island with rather modest equipment but might regret not having the ability to invest in equipment more appropriate to serious recreational listening. Does that answer your question?

      Alan, Are you running PC USB out -> USB in DAC -> Aamp - > Speakers?
