I have a pair of newly built, fully upgraded AV123 X-LS Encores for use as front mains. They sound really great, but I was wondering by chance if any Audio Circles members may have built the AV123 MTM X-CS Encores with all the performance upgrades ( Sonicap capacitors. Mills Resistors, No-Rez sound damping) for use as front mains. If so, what is your opinion of their performance compared to the fully upgraded X-LS Encores? I know the X-CS should have higher sensitivity, play louder, and have greater bass output than the X-LS Encores, but what about their imaging and sound field depth and overall clarity / detail ? Bottom line, is the performance of a fully upgraded pair of X-CS Encores significantly better than the X-LS Encores as front mains?
