I would be shocked it you didn't like any one of those better.
I am quite sure I would appreciate them all. They all have a great reputation but I am sufficiently happy with the DAC1 that I have no urge to change. I think there is a stage you reach where things begin to be only a bit different but not necessarily a lot better and the DAC1 is sufficient for me. I don't doubt that by trying ten different DAC's or spending five times as much that I might find one that is slightly more suited to my tastes but the difference will not be material enough to me to be worth the money or time. To be honest I found the difference between the DAC1 and stock Sony CD player to be audible but not huge...nothing even remotely approaching the difference I hear between one room and another or one speaker and another.
