Since the beginning I was doubtful 80dB of gain could be achieved with this design... at least with any kind of respectable fidelity. Early on I set my goal at 70dB. The first many prototypes peaked out at around 65dB and that was not with a flat 20-20kHz response. Over the past couple days I had some major break throughs. Trinity now has 80dB of gain, -90dB S/N ratio, 0.204% THD+Noise, and a flat frequency response (+/- 1dB) from 20Hz-20KHz with a total response from 1Hz-100kHz. It sounds fantastic. I worked out all the bugs with this new batch, so its finally starting to look like I might be just a short step away from a final product. A little bit of stress has been lifted from my shoulders. Looking forward to the next step!
