Excuse me for sleeping through the audio technology of the 90's, but what ever happened to 1 bit d/a converters? I remember how my first original CD player has dual 4 times oversampling 16 bit d/a converters, but then I recall after going with 18 20 and 22 bit converters they went to a 1 bit converter and 16 times oversampling [ not really oversampling since it takes 16 samples to get 16 bits ] At least, thats what Matsushita did with their MASH technology. So how come my Marantz receiver contains 24 bit D/A converters instead of a 1 bit 16 times oversampling converter? I thought the 1 bit technology of d/a converters were more widely adopted. How many times oversampling does my receiver do? Only two times at 96 khz? Does Technics and Panasonic still use the 1 bit MASH technology?
