Does anyone know the frequency response of the DS dac when sacd is being utilized? Redbook shows 20-20KHz +/- 0.25dB but no numbers for sacd. Just curious.
The FR of the DS and DS Jr is flat to just shy of 50k for all inputs (if they have a signal there.) Tho it’s probably listed as 20 to 20k because that’s more or less standard for audio gear, one reason of specifying Redbook is to show that the DAC doesn’t roll off the top either in the analog output or with a digital filter (say by using an apodizing filter that rolls off before 20k.) For Redbook the DS is flat to about 21.7 KHz
Thanks for that Ted.
