There are lots and lots of powerful amps out there - but only those that unconditionally control the connected loudspeakers with a grip of iron and an extremely high damping factor bear the name of HELIX. The output stages of the competition line are what the high ender calls "wired for power". Whether it's sheer power or enormous musical sensitivity – these power packs know every trick in the book. If you finally want to stop looking for the perfect amp, then this is where the search will end.
