The Vintech Audio 273 is a discrete Class A stereo preamp based on the classic Neve 1073. All discrete, transformer balanced and up to 70 dB gain.
The 273 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).
