Hi Pal... So, I'm thinking about maybe adding another preamp to my rig in the next month or two. As you probably already know, I'm currently using Presonus XMax pres for the bulk of my recording. I know that you have the Focusrite ISA 1.. and I know you like it. If you don't mind, could you talk to me a bit more about this model? Sonics, overall sound, gain, transformers, etc. Is there something that you like using it on the most? You've heard the style(s) in which I produce... would this be a good choice for me? Do you find that the Lundahl tranny makes a difference? FWIW, I have AKG 414EB's (2), a Neumann U87, a U89i, EV RE20, various dynamics like 57's, 58's, Sennheiser 409's, ... and an MXL 860 Ribbon. Also, do you have the straight pre model or did you get the optional 24/192 i-o ? If I decided to go with an ISA, would I be able to do without the digital i-o, and just use my existing Presonus VSL as the ADDA input/conversion stage? Would I see a drop in the quality of the ISA if I did it this way? Thanks in advance... -d.
