Just re-flashed dsdclk.. It is indeed better suited for my setup. More laid back. Very enjoyable, more refined i find. The soundstage has better depth. Best fw so far for me, but not by a mile. My ears will thanks me at the end of the night. The latest is just too bight and punchy for me. Dsdclk has a perfect midrange, the latest is recessed in comparison. I now am on OS8. Took a while before i fully appreciated it but dsdclk is great, near perfect for my tastes. Not sure anymore it needs anymore dynamics. Perhaps just a pinch... Anyway, as in the song, i love it just the way it is. These latest parallel fws are heading in the right direction. You can hear they are more resolving and smoother. Great stuff. Message to Kingwa: i desperately need the new DI. The u16 has hung on me 10 to 15 times over the last 3 days. It is driving me nuts.
