I generally store my music as ALAC in itunes. I'm using this as source to feed an upsampling Chord 64 DAC. The only problem is on the upsampling setting there is an annoying 4 second delay. I'd like to know if its possible to upsample the music on the mac and I dont have to make use of the upsampling feature on the DAC. The 4 second delay kicks in after every song so its quite a problem. I recall there being something in Foobar that upsamples??
