Hi Anthony, I have finished the modification and it's magic ... the speakers never sing like that (focal elektra 1027 be) the sound image is open, soft and very precise, all the little details are there, nothing is aggressive and the bass is firm, just punchy. these amps give me chills, the musicians are in my living room and I rediscover my music! Anthony you are a music magician. thank you for your presence and your work. Merci beaucoup ,portez vous bien vous et votre famille au plaisir Christophe Henri ,  saint michel sur orge France
