Greetings. I want to change my current setup to the one FOCUSRITE SAFFIRE PRO 24 sound card mainly for improvement in recording Vocals and Acoustic Guitar. The problem is i have no idea that this change does really affect my recording quality. My current setup: - Infrasonic Quartet 4x4 Pci interface (I just use Line-in and not Its own preamp) - Behringer xenyx 1002 fx ( for its preamp) - Akg perception 400 Condencer mic. - SM pro MC01 Condencer Mic. Please tell me what you think, and any other recommendation.
