So far with just having hooked up my ifi's to the m-audio sonica theater, they sound much better compared to my apple powerbooks headphone out. Currently i have the m-audio set to 24bit 96khz but there are tons of other setting i can adjust like speaker placement in feet, crossover point(40hz-120hz), 2.1, etc... Now they also have pre-set settings for the klipsch 2.1, 4.1 and 5.1. Would using the klipsch 2.1 presetting be beneficial or should i just manually adjust the settings? and if so what settings should i have them at to get the best sound out of the ifi's? thanks everyone deff worth the money.
