The F670ES is a upgraded F570ES. Both amps share the same pcb-set,but F670 has 4x 12000ÂµF instead of 2x in F570. Inductors are added in the powerlines for the driverstages and a couple other passive parts are of slightly higher quality. Does that make the F670 the better amp? A little bit,but not realy noticable. What i wrote for the F570 applies also for F670.
