I'm shopping around for a bus powered 2-channel firewire audio interface for my MacBook Pro. I currently own a M-Audio Delta 1010 that I'm very happy with. I've read everything I could find about the following 3 interfaces which I believe to be in my price range and offer what I'm looking for. Apogee Duet $499 TC Elect. Konnekt 24D $399 PreSonus FireStudio Mobile $299 Unfortunately the situation I'm in doesn't let me use my Delta1010 all the time. I live in an apartment, and have no dedicated area to set it up, so I'm constantly setting it up and taking it down when I'm done. This makes recording quick song ideas a real pain in the #^$. I want to be able to seemlessly use recordings from both my Delta1010 and Firewire Interface in the same song without much difference in sound. In my research the general consensus I've seen is that the Duet and Konnekt 24D have equal sound quality DAC's and ADC's. The PreSonus is slightly below them in this area. I've also read the Apogee Mini-DAC is better than all three of them but at $799, I think that's more than I'm willing to spend. Things that are important to me: DAC and ADC Quality Phantom Power Bus Powered Firewire Monitor Out At least 2 Channels Compatibility with Logic Any extra features are nice, but not really a necessity for me, it's just a portable easy to setup configuration in addition to my Delta1010... not a replacement. I guess at this point I've really narrowed it down to the Duet or the Konnekt 24D. Does the Konnekt really sound as good as the Duet despite the price difference? I know the Duet is tightly integrated into Logic, but I'm assuming the Konnekt would do just fine for my needs? Are there any other interfaces I should be considering in this price range? I've done all the reading I could on this one, but I feel like my needs are a little unique which is why I made a new post.
