Miroslaw’s Burson V7 Vivid and Vivid Pro Opamps with DALI Zensor 7

Published on

Post Info

I’m new to this, so I don’t have much experience yet, but I’m hopeful that the results will meet my expectations. Recently, I upgraded the standard op-amps in my Fosi ZA3 by replacing them with Burson V7 Vivid Pro op-amps. As shown in the picture, the Burson V7 Vivid Pro op-amps are already installed in the Fosi ZA3, and I’m excited to see how this change impacts the overall performance.
