Synergistic Research Quattro multi supply ?'s

I am considering picking up a Quattro power supply to power the activive shielding on my I/C's and speaker cables. Has anyone upgraded to the Quattro from the MPC's and if so did you notice any change in sound? Did it actually make things easier to route or not worth the extra dough? How much do the Quattro's run and now many connections are supplied with the unit? Thanks for any help in advance!
