I'm purchasing a UA 1176 compressor, Great River ME 1NV pre, and an Avalon M5 preamp, and API plug-ins as well, just wondering what is the best a/d converter to buy for my setup. I'll be recording acoustic guitar, vocals, piano, strings. Right now i have a M-Audio profire 2626 and planning to use it as a converter only. It runs at 192kHz. or am i better off getting a better converter? if so, which ones would you recommend? and i'm using Cubase 4.
