I'm a newcomer to this great site, so I apologize if I am asking redundant questions that have been hashed out ad nauseum. I've been looking at interface options for my home system. I'm mainly running a Mac G5 with ample RAM and with Logic Pro software (also with a Waves bundle and various other plug-ins). I've been using the M-audio "Project Mix" as my interface (i.e., a gooey, much like a Digi002, with sliders and transport controls for that "hands-on" experience). Reckoning with the likelihood that the preamps on the Project Mix and its AD conversion are not high quality (this unit cost ~$1,000, with Protools included), I'm looking at options for upgrading the interface. I rarely record more than two channels at a time, except for drum tracks, but I feed the drum mics through a Mackie mixer with Onyx pres and go audio out in to the Project mix, and this sounds OK for drums. So I'm really looking for better fidelity on the vocals and other instrument tracks. The Apogee Emsemble has caught my eye, with 8 channels of AD conversion and 4 supposedly fine preamps. It features S/PDIF, ADAT and optical digital I/O options, so I could take two channels of S/PDIF into the Project Mix (as a possibility). But it looks like the main interface with the computer is via the firewire (bypassing the Project Mix). I have heard that the Apogee firewire has some latency issues (like a other firewire routing), and friend has been telling me that I'd be much better off with a Motu AD converter (e.g., the 12-channel HD192), because apparently Motu's proprietary firewire is faster, with zero latency. But there are no preamps on the Motu, and I don't really need 12 channels. I'm tempted by the Apogee Emsemble, but I noted that Musician's friend is dumping these units at a reduced price, and so I'm leery of possible latency or other quality issues. Any helpful insights and suggestions would be greatly appreciated. I also should add that I have a Yamaha 24-track "studio in a box" (AW2400) that I use for recording live performances of my band and occasionally for tracking at home, and this has a 2-channel S/PDIF input. So I could potentially interface the Apogee with my Yamaha and bypass the cheap AD converter and pres on the Yamaha. decisions, decisions!! [Sorry about the long message]
