Mission accomplished! No more metallic shimmer not supposed to be there riding on the highs. I think it was the SATA cable, the entire system with this 4$ Coboc SATA cable now sounds better than even. Smooth, relaxed and natural while still very detailed, dynamic/powerful and transparent. Again very happy, now hoping it stays this way. Perhaps I should cancel the new server parts orders!
