I am looking to get a better A/D interface; I currently have the M-Audio OMNI Rack. I would really like to get the Apogee AD-16X! What are some converters that are a notch below the Apogee converters-MOTU, RME, etc? I have gotten suggestions to check out the RME stuff because of the quality to price factor of their products. Has anyone heard the ONYX board-if you get the firewire interface you can basically use it as a converter. The pres are being advertised that they are really good; if the pres are really good on those boards, then that might be a really good buy!
