χωρίς να βγούμε εκτός θέματος....
γιατί τόση πρεμούρα να φύγουν τα placid έναντι του Σάλα?
(δεν έχω διαβάσει σχετικά θέματα...)
H χαρά του DIY!
Tου Salas είναι επιβεβαιωμένα καλύτερα για τροφοδοσία 5ν και πάνω!

Hi guys, is it the simplistic shunt reg v 1.2 superior to Twisted pear audio's Placid ? I suggest yes, but how much? Any suggestion?
answer:
Not bad, but can be done better.
Single transistor as CCS is not very good choice, too low dynamic impedance.
"More devices" mix is better choice here to increase dynamic impedance.
Powering opamp from raw supply is not very good idea since you are relying only on opamp's PSRR. And opamp's PSRR will fall as frequency is increasing. Powering opamp from self regulating power supply is much better choice.
CFP after opamps is not best choice. Single device there is better choice.
Everything already mentioned here by Allen Wright and Maximus (Paul Hynes).

"I compared vs Salas V1.0 remote sense (better Salas) & upgraded to Salas V1.2R (better than Salas V1.0 remote sense)
I sold my Placid several months ago here."
