With high-voltage tube amplifiers and glue-like abilities for your mix buss and mastering chain, Avalon's VT-747sp Stereo Tube Compressor / Equalizer is a prime candidate for that final kick your music craves. Gel together your mix with the smooth optical compressor, and then bump up the air with a bit of graphic EQ to get a radio-ready sound that can't easily be had with digital plugins and lesser boxes.
