hi MacMusicians..

i am thinking of buying an M-AUDIO DELTA AUDIOPHILE 2496 today... to be able to get my electricguitarsound into my mac and start making music digitally...

however I am wondering if anybody has experienced a sort of BRUM BRUM-sound from the Mac... because my G4 (Dual 450Mhz 768Mb) is from 2000 and it sounds a bit... the cooler I reckon...
Will this "noice" affect the digital sound when it enters the computer from an M-AUDIO DELTA AUDIOPHILE 2496

and if so... is there anyway to wash or polish this mis-sound away?
