DIYRE OLA5

I built this myself works perfectly.. I put a Capi 2520 Opamp in that I also built myself.. Very nice clean unit.

Classic Opto Leveling, Upgraded Signal Path. The Urei LA-4 leveling amplifier has always lived in the shadows of it's older siblings, the LA-2A and LA-3A. Despite possessing the distinctive, musical compression character its family is known for, the LA-4 was compromised by the muddy sound of early chip technology.

recreated the LA-4's leveling behavior—including cloning the original opto cell after finding that no modern substitute would do—but that's where the resemblance to the LA-4 ends. The OLA5's signal path is completely overhauled and upgraded. And the workflow hews closer to the LA-2A and LA-3A, while adding new features like a sidechain high-pass filter and parallel MIX control.
