Fractal Audio Systems
If you don't like this firmware then your ears are shot. I went through every single model that uses a cathode follower and compared it to the real amp. That's why it took so long. My ears have gotten quite refined and even I was guessing wrong at which was the amp and which was the model. The second to last amp I tested was my all original black panel SLO 100. IMO the model sounds better than the actual amp because the model doesn't hum as much.
