Upgrading to the SS2590

The SS2590 PRO discrete op amp was designed to be as sonically transparent as possible.  Our design philosophy is  "a piece of wire with gain" to give the most accurate musical reproduction and recording that is possible.  What you hear is what you record, and every effort has been made to preserve the artists tone, timbre, and timing.  These devices can replace any 6 pin, 1 inch square type of op amp that are integral to many Mic Amps, Lunchboxes, compressors, EQ's and Mixers that are found in most recording consoles.
