Sumo has made some very interesting products over the years, some really good, some just okay. The Diana preamp belongs in the former category. It is a two chassis unit with a separate power supply and was Sumos most expensive preamp offering.
Design and layout was simple and direct with a major emphasis on sound quality. This was clearly audible when you listen to it. The bass/mid-bass is a bit on the heavy side but is balanced with a nice transparency and a dark background.Soundstaging was good and the meaty mid-range provided a full bodied sound.
