In every single sales point, this is utter nonsense.
If the data read from the SSD is altered by the voltage supply of your motherboard, your whole system would be in serious trouble, I doubt it would boot up at all. Buffer caps of this size are not needed at all on regular systems.
High precision clocking is another complete BS technical detail of this SSD - the data gets RAM-cached on the SSD (tiny internal controller RAM buffer oder larger external RAM buffer), transferred into computer RAM, processed by CPU, piped out via PCIe to a DAC, passing at least two more, probably three, RAM buffers. So your output signal gets passed around buses and caches several times - a precision clocked SSD controller has no influence whatsoever on your output.
The only failurepoint of a SSD however has been completely ignored. Talking about "controller heat throtteling" here. Which *is* an actual issue, alas not as much on audio streaming data transfer rates though.
