ok, i do all home recording by myself and never track more than 2 intruments at once. i own a junky usb mixer and a junky pre-amp right now and am looking to upgrade. i'm wondering which is more logical for me to get: a decent pre-amp or a decent mixer? remember, nothing over-elaborate, since i never record more than two instruments at once. could you guys recommend some decent pre-amps (mainly for vocals) and decent mixers (possibly firewire). i own a imac with osx, 3.06GHz intel core 2 duo, 2 gb 800 MHz DDR2 SDRAM, Rode NT2-A mic. the junky mixer i have right now is a yamaha mw10 usb mixer, and the pre-amp i have is an m-audio audiobuddy. please lend me guidance....
