I have a high end audio application in which I'm using the NE5532 opamp. I'm processing an audio signal with 10Vpp swing (so between +5V and -5V) in an audio ADC input stage. Does it make any difference for the audio quality whether I use +/-14V or +/-11V as supply rails? If yes, why?
Additional info: my converter takes differential inputs, each input between 0 and 5V. My circuit feeds it two signals centered around 2.5v, each 2Vpp so after subtraction the ADC sees a 4Vpp signal. This is a 32-bit converter and the sample rate I'm using is 192kHz. I cannot change the converter. Given this scenario, does it matter sound quality wise to use 11V or 14V rails?
