The 1073MP preamp yields a really fat sound. It seems to add subharmonics to the low end which makes the bottom end sound huge. It smoothes the top end which gives the highs a silky sheen. As well the 1073MP compresses transients a little bit. It is a smooth, fat., larger than life sound. An added bonus is to use the DI inputs to fatten samples, synths and mixes since the DI can handle line levels.
