I often wondered how amp-producers implements the conversions back and forth from Material (like vinyl or CD) to DRC (like Audyssey, Dirac and Trinnov a.o.) to speaker output.
How many conversions are there?
Material: Analogue or PCM or PDM with various bitspeeds.
Input: what conversion to digital does various amps make?
DRC: How many and from/to what format do Audyssey, Dirac and others use?
Preamps: with volume a.o. what digital formats?
Poweramps: IF a digital amp, then a final conversion to PDM to feed the amp, otherwise a DAC to feed the amp.
How many conversions will that be?? And how much dist will that add?
Why are DRC-vendors so secretive about what format they use for their filtering?
HiFi would benefit from as few conversions as possible. How about a standard for internal use to be used by all? Like PCM 44.1kHz 16 bits for cheaper models and perhaps 192kHz 24 bits for topend. Same software just selected by the amp-producer to differentiate their productlines.
Especially important when several different DRC shows up in the same amp, like Denon, Marantz, Pioneer a.o. which can have both Audyssey and Dirac on the same amp.
What do YOU think?
