In the current filter set (firmware ver 0.06), in my system I found the best sound for 44khz material is #2. The best sound for everything else, i.e. 48/88/96khz is filter #1
John Marks in his March issue of Stereophile said he still prefers #1 in the updated filter set, I guess may be because he used 48khz material for comparison. For CD material, you should really try #2 before formulate your opinion on the dac.
