I'm down to these three. I don't need the pre's, and i don't necessarily need the UAD processing as I already have a UAD duo card. I could always buy a used rosetta 800/FW but I dont want to buy used if i don't have to, at least if i can't test it. What would you guys say? This is for my home mixing set up, as i don't like having to drive downtown to the studio just to mix everyday. Signal flow would be the interface(need 8 channels minimum) into my focusrite(audient design) control 2802 console, and then the mix o/p back into the interface to print so that I can add in my La-2a comp and my trident eq's through the 2802's inserts.
