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!"

Distance between pre and power amp?

  • Distance between pre and power amp?

    My hi-fi and speakers are at opposite ends of the room, so I need 10mts to reach the farthest speaker.

    Is there any advantage in using a long interconnect between my pre and power amp to keep speaker cables short?

    My Arcam pre has both buffered and direct phono outputs for the amp.

    Hello Stephen,
    it is not recommendable at all to use such long runs of unbalanced interconnect cables.
    Go for long speaker cables. I'm using Van Damme blue series studio grade speaker cables, so I think, due the high quality and very acceptable price (1,85 ? for 2x2,5 mm2 and 3,23 ? or 2x4mm2) you can give them a chance.

      Hello Stephen,

      I agree with Vlado, general acceptance is long speaker cables or balanced interconnect between pre and power amp...

      Good luck!

        Thanks for the replies, I'll leave it as is.

          I think that I'd prefer to extend the speaker cables rather than the interconnects unless the interconnects are balanced and/or the output impedance of the preamp is low - say under 1kohm - otherwise the capacitance of the screened lead from pre to power amp will inevitably roll off the extreme top, depending on the length and construction of the screened cable.

          If the power amp input is fed from a balanced source using balanced cable, there is no need for that cable to be screened: it can't do any harm if it is screened but it's not mandatory and never has been in professional studios.

            I also the same set up as in the speaker and amp are on the opposite sides of the room and I am using 7m run of speaker cables.

            I am using the QED 79 to good effect. It is much cheaper to have 7m per side of QED 79 then to have long interconnects!

              I personally can hear much more of a change in longer speaker cables than interconnects. 30 feet of speaker cable is going to have some resistance. When you look at say 0.1 ohms resistance for a great cable it might not sound bad but that is in referrence to a 6 ohm resistance of a speaker. Looking at most power amps the resistance is in the neighborhood of 47000 ohms and carries much less current which both are going to affect the signal to lesser degree. Sorry to say but I really can't hear any difference between my different interconnect cables long or short runs, or different brands. My main speakers in my most used listening room are electrostatics and they dip into low resistances and this might not be such a large factor with the Harbeth's which are in a smaller room and all my runs are quite short.
