Those companies are using Alesis chips, but not necessarily as the A/D or D/A chips! I know for a fact the PreSonus is not using the Alesis A/D chips, and that Behringer is not using Alesis A/D in their DDX3216. Behringer is using AKM A/D and Crystal D/A in their DDX3216... DDX3216 I can't remember what the Digimax uses, but I spoke with their Tech support folks about upgrading my unit to 96K (mine only goes to 48K), and they gave the details, but I have forgotten now...sorry. Here is a page from the Presonus web site with a few reviews, and interestingly enough, all 3 reviews talk specifically about the A/D: Digimax Specs and Reviews I really love my Digimax for many uses. I am however in the market for a high-end mic pre right now, and am seriously looking at the Sebatron as well as a few others. Does that mean that I am going to get rid of my Digimax? No way! My new pres will just be there to compliment the Digimax. Also Kurt, your comment about "clocking to Cubase" confused me...Cubase is software, not sure how you can clock to that. With regard to clocking, a common impression is that you can improve the quality of the A/D by clocking to a better clock source. I bought a Lucid Genx6-96, and swear that the converters in the Digimax sound better!!! Any comments on the usefulness of a good clock?
