Además comenta que esos períodos de rodaje de cientos de horas son más bien para que el oyente pueda reprogramar su percepción, vamos, que ese pase a ser su nuevo "standard".16. Do I need to 'burn-in' my Harbeths?
No: the only component part of a Harbeth loudspeaker that can change as a result of the exercise known as 'burning-in' is the resin-doped cloth suspension that centres the neck of the cone in the magnetic field - sometimes called the 'spider'. Under the microscope, once the resin has been worked, it crazes into millions of small interconnected islands. This process is irreversible and takes only a few hours - or less, with bass heavy music played rather louder than normal. After that, the drive unit can be considered fully aged, and the resonant frequency has settled at its final value and will stay at that value.The ferrofluid used in Harbeth tweeters will become appropriately viscous after a few minutes operation. Neither the coils, resistors, capacitors, cables no any other part of a Harbeth speaker has any short-term ageing mechanism.
As discussed in Designer's Notebook Chapter 7, "When one hears reports of a loudspeaker 'needing an extended burn-in period, maybe hundreds of hours' this has little or nothing to do with the ageing process of the drive units but of the listener attempting to reprogram his fight-or-flight response. At the top of the design specification of all and every Harbeth speaker is that it must not be fatiguing to listen to hence, by implication it must not have an over-vivid phantom image".See also the User Guide section.
