ART Digital MPA II
Bang for the buck, this this preamp is really, really good. It does what it's supposed to do with no muss/no fuss. Key features that drew me to it were the insert loops (although disappointed that the loop only works in digital out mode) and the ability to use it in analog out, or digital out modes. My rating of 5 stars is based on price point, as there are many, many more preamps on the market which are esoterically higher performance, but will cost light years more money. All-in-all, I'm very satisfied with my purchase.
