I have owned the Cosecant V3, Havana and Paradisea +. I had the Cosecant and Paradisea + in the system at the same time and I thought the Paradisea at 1/5th the price beat out the Cosecant and the Havana I found to be slightly better than the Paradisea so my guess is compared to the Proton which I have not heard the Havana would be better
