This opamp was designed by Gary Barnett of Barnett Industries. It's is an eight transistor amplifier modeled after the legendary Melcor 1731. For those who do not know it, many of the engineers responsible for the Melcor 1731 left Modular Audio Products around 1968 to join forces with Saul Walker when he started API. The starting point for the famous API 2520 was indeed the Melcor 1731. Back to the beginning I guess one could say!
Overall, it's sonically very similar to the sound of a 2520. The gar1731 has a slightly smoother bottom and top, while simultaneously retaining the ever familiar aggressive, forward midrange we love about the 2520.
Some of the applications the gar1731 DOA can be used for: Microphone Preamplifiers Line or Booster Amplifiers Lossless Combining Amplifiers Balanced Transformerless Amplifiers Equalizers and Compressors
