TPA3255: Power Supply Ripple

Part Number: TPA3255

Can you tell me what the relationship is between power supply ripple and SNR, or other performance affects? This question is specific to the noise characteristics of switching power supplies. Per the literature on the topic, Switching Power Supply low frequency ripple and high frequency noise occur well above the audio band (500 khz and above). Does TI publish or recommend specifications for power supply ripple and noise to obtain the best performance from the device?
