BAE 1073 Single Unit With Power Supply  The 1073 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 1073 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.¬†
