....About the Egoista 845, the machine is the same in many ways, but with some improvements. First of all, after some number of units produced, we refined the construction, and overall it is better done. Also, we worked on various voltages and current, and distribution of it, and we could reduce further the noise, and improve the sound as well. It is hard for me to describe, just, the machine is more "straight", with better dynamics in low region, and better timbre rendering. Not night and day, but substantial improvement. We could also get rid of the noise compensation pots, finally (they never meant to be stable, but we could remove them only now...).
