On my system (B&W PM1/Devialet 120) firmware 9.0.1 is the best so far. Previous FW's have been on the bright side to my preferences, causing sibilance problems. In version 9.0.1 sibilance problem is gone, and tonal balance is no longer on the bright side. I really like what I am hearing right now, playing Beck's Sea Change :-)
