interessante:
Neutral sound
Some devices have a reputation of reproducing sound in an analytical way, suitable for persons with a taste for the detailed.
These devices are often made with a lot of resonance and self oscillation. This has the result of causing transients to generate resonance, which in itself is a delay of the signal: instead of just passing through, the singnal stays, similar to the ring of a bell.
If a loudspeaker with low resolution is connected to an amplifier of this type, transients and detail that was not audible with a correctly made amplifier suddently appear audible. This is an illusion however; what becomes audible is the resonance of the inaudible details, not the details themselves.
A high quality CD/amplification system on the other hand, connected to an “analytical” loudspeaker can in a worst case scenario result in humming or rattling from the loudspeaker.
Many devices on the market today contains very many flaws and/or downright errors that ranges from bad design of the logic boards to use of cheap components.
A good HiFi dealer can combine devices in a competent way so the end result becomes acceptable.
For example, connecting a CD-player that sounds thin to a high quality DAC will yield a poor result. Connecting it to a DAC that muffles the signal or maybe even add colouring to the signal, the result may become better, beacus the flaws in the DAC are of the “right” kind. The sound is not thin anymore.
Mi ha spiegato perche' per me certi ampli osannati come Accuphase mi sembrano assurdi:vanno bene solo con diffusori poco rivelatori.
