The Audio Mirror is too laid back.I'm not sure what laid back means, but like any piece of gear, the sound depends on everything in your system.
In my system, the Audio Mirror Tubadour lll SE sounded great. At the time, I had a Herron VTSP-3A (R02) pre amp and NAD M22v2 power amp with an Innous Zenith MKII streamer. I was quite happy with that combination.
I decided to upgrade to a full PS Audio stack (BHK pre amp and BHK 250 power amp), and replaced the Tubadour with a DirectStream DAC (DSD). With the PS Audio stack, the DSD sounds more "analog like" than the Tubadour.
OP, having said that, the Tubadour is a fine DAC. If you are not in a hurry, I recommend you call Vlad and test drive one in your system.
