Matt, yeah the SCD-025Mk2 is a wonderful sounding rb dac. Of the other dacs you mentioned, I've only had direct experience with the Soulution 500 & 700 series spinners & CH D1 with the optional dac board. Of course I really liked the Soulution 745 which sounded amazingly smooth, resolving and musical, though not cheap!
I also run a Vitus SIA-025 integrated which is a lovely integrated & had planned on upgrading to the new SS-025 power amp & SL-102 pre, but re-ordered my priorities and am now upgrading my speakers to Magico S7's which I think will give me a bigger improvement.
