Well I guess on the Farad website they publish what’s in favour of them ;-)Check the reviews on Farad's website. My memory is foggy but I recall one that looked at both the Farad and another from Keces.
I guess the Super3 is better than the P8 but others have mentioned the P8 is emphasizing mids a bit more. Apart from that there is an excellent overview of leading LPS at https://audiobacon.net/2021/08/06/the-worlds-best-audiophile-linear-power-supplies/
(Unfortunately missing iFi iPower Elite and Keces P8)
