I'm in week two of a 30 day trial of the PS Audio Directstream Mk2 DAC. I would say that it is is "lively and energetic". It is worth a listen. PS Audio has them on sale now for $5599. I'm comparing the PS Audio to my Lumin T2 DAC/Streamer. The built in Lumin DAC is very good but I am leaning towards the PS Audio. Again, the PS Audio eeks out a little more detail and is more dramatic in it's presentation. This may be too much of a good thing until the unit begins to break in....which is in the process now. Sounding better every day.
