Today I have spoken with A.J. Vandenhul via telephone. He told me to change order of cables, between cd and pre ''second'', between pre and power ''Mc Silver mk3 balanced'', and finally Supernova speaker cable. Since I have ''Second'' XLR I couldn't employ it between dac and pre since Musical Fidelity kwdm25 dac has only rca output. I put my reserve VDH Jubilee silver hybrid between dac and pre and Kept ''second'' between pre and power. To be honest, when I heard first my setup after cable change, I felt like midbasses improved, detail, clarity improved, but most importantly I had a feeling that sophia's tweeters are upgraded to Focal Be tweeters.(I wish David Wilson will see ''Be'' tweeters on his designs before he passes away)
