I've had FW 1.4 since it came out. At first it seemed quite OK. But now, I will rather go back to the original FW. It seems that on the new FW the hights are a bit brighter, and low ones are stronger. However, on the original FW I like the reverbs more. Someone wrote that he does not understand why change the good sound. I think the same. For me, in my system, the Pontus II on the new FW approaches sonically other DACs that sounds clear, detailed and detailed. That's not what I'm looking for in music. It would be primarily musical, not detailed. I'm going back to the original sound soon, the one that was at the beginning, because that's what I liked.
