Wow, thatnks for that info. I usually use a triple cap in my PS caps - a low ESR like a Panasonic FC or a Rubicon ZA/ZL at 2200uF or 1000uF depending and then bypass with a Wima MK4 at 2.2uF and a Siemens NOS stacked polyester 0.01uF. I have found that this combo works very well in my power rail stiffening applications. In general I took this idea from Thorsten Loesch when I was building my phono preamp and have applied it to the Art DIO mods I did too. When my Siemens run out, I will look at both the Epcos. -- mamsterla ------------------------------------------------------------------------ mamsterla's Profile: http://forums.slimdevices.com/member.php?userid=469 View this thread: http://forums.slimdevices.com/showthread.php?t=19822 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
