I have been running Logic the OS and the projects off of this set up. I just tried running Logic and my OS off the internal and opening projects from the RAID drives. Still no difference. I can hear a difference in quality now that I'm in 24 bit. I must admit I'm not sure what I'm gaining from the 192k. Is it advantageous to step down to 96k or just stick with 44.1 / 24 bit. Also as I am still new to Logic, how can I convert my audio files at 192k down to another sample rate? thanks for your feed back. Aaron
