Hola, This is a multi-part question (as usual). Thanks for your patience. I currently have an RME/Nuendo 8 i/o interface (48khz) going into a 002rack. I also use a Universal audio 2108 pre and I have 2 avalon U5 DI's that I use for keyboards, Rhodes piano, and bass guitar. I am essentially trying to build a 5 rack space "portable" setup for my powerbook, that I can transport around (no more than 6 mic pre channels needed at a time- I will have a home studio for mixing, while I will be tracking at a friend's house). I am looking into selling my Avalon U5 DI's, and also my RME interface, to get a Focusrite ISA428 with the A/D card. This a much more portable and all in one solution for me, as I would put the 002r, the 2108, and the focusrite in a rack, throw the powerbook in a backpack and have a kick ass studio in a small package. My questions are::: 1. Is the conversion quality of the Focusrite A/D unit up to par with my RME? 2. Will the Focusrite suffice as an instrument and keyboard DI? (the u5's are nice, but clunky and heavy and I don't use them too much- I've actually been using the 2108 for my rhodes lately) 3. Will the Focusrite and Universal Audio pre's be different enough in character to give me a diverse selection of sonic possiblities? (I LOVE my universal audio pre, but would like some more selection). 4. I assume that the Focusrite ISA pres are going to blow the 002r's pres away...or are they? I haven't really had a chance to demo them yet (002r's pres), so if anyone has the same setup (ISA with 002rack), that would be great if they could chime in. Thanks so much for everyone's patience and help, I feel like a kid in a candy store in this forum!!!!!!
