Forse per una questione morale, quella di non manipolare il segnale ?

Lasciamo perdere allora, se dovessimo conteggiare le operazioni che si effettuano nel momento in cui il suono di un evento viene catturato dai microfoni fino ai nostri locali ci sarebbe da mettersi le mani tra i capelli.

Forse la lingua italiana avra significati diversi, ma non credo. 

Ripeto, hai fatto tirato in ballo una questione che non sta in cielo ne in terra, come al solito.

Quando si Produce, si manipola e si modifica. A prescindere dal purismo o sofismi usati. È un dato di fatto.

Quando invece si Riproduce, la minor manipolazione possibile è sempre la beneaccetta, e questo porta ad avere riproduttori il piu  lineari e poco manipolatori possibile.

4500 discrete parts distributed over 40 separate printed circuit boards. The power supply is elaborate, with distributed
regulators next to the circuits they supply. There are five stages of initial DC regulation followed by 30 local regulation stages.
A power supply regulator smooths out any fluctuations in the DC voltage that supplies a circuit. A large number of regulation
stages better isolates the subsystems from each other as well as delivering cleaner DC to the audio circuits.
Cascaded regulation,
in which the output of one regulator feeds the input of another, results in smoother and quieter DC. Indeed, Wadax claims the
total noise on the voltage rails is 0.5μV
(1Hz–100kHz), an astonishingly low fig-
ure. This is a very sophisticated power
supply by any measure.

The Studio Player benefits from
Wadax’s proprietary “musIC 3” feed-for-
ward error-correction system
that oper-
ates in the time domain. According to
Wadax, “by mapping the error mecha-
nisms of a chosen DAC chip under load
using Adaptive Delta Hilbert Mapping,
we can develop an algorithm that exam-
ines the incoming signal and calculates
the induced error (both linear and non-
linear) that will result. By applying an in-
verse signal at the input, we can real-time
correct for the time and phase error that
is so musically destructive in other, conventional decoding sys-tems.
This process requires a massive number of mathematical operations and a considerable data transfer rate of 12.8GBytes/s.
Processing is done at 128-bit internal resolution to precisely render the output and generate the smallest feed-forward correc-
tions.” This Wadax-developed technology has proven itself in the Reference DAC

How does the musIC3 process work?
The signal path in the entire digital-to-analog converter has a transfer function which is the relationship between the input and the output.
This transfer function is the essence of how the analog and D/A circuitry changes the signal. By modeling this transfer function, it’s possible to predict (i.e. simulate) the real output of
the whole system before sending the audio content to it. This prediction allows us to identify the desired output and the error
that will occur. Conceptually, feed-forward means changing the input data so this change cancels the predicted error.
This is opposite of feedback, where the error needs to be measured at the output to be fed-back to the input.
This loop takes some time to be corrected, so the maximum correction frequency is limited, as is the amount of error reduction. Feedback is a cost-effective approach for many applications. In contrast, feed-forward is not inherently limited in frequency,
and the error reduction can be as good as themodel of its transfer function. But it is alsomuch more costly to design and implement.

@davenrk

Il Mighty è così, ha tre parole tre nel suo modesto vocabolario

e le usa in modo stocazzistico, anzi stoccafissistico.

Eppur ci gode.
