The Vintech Audio 273 Class A discrete stereo preamp is the same preamp used in the Vintech 473 and X73i. It has 70 db of gain (think of it as a 2 channel version of the 473). It also has simple EQ on each channel, 'reductive or additive' per hi or low shelf. Great for brightening, dulling, thinning or making the sound fatter during tracking. See our X73i review to see how we felt about this unit (again has the same preamp as the X73i with just more limited EQ'ing choices).
