New Luxman DA-06 doesnt sound so great. Will it get better?

Hi, I recently received a Luxman DA-06 dac (new, gray market Japan import) and it the sound doesnt seem to have any life.  It sounds a bit dull, uninvolving, and just low fidelity.  The best way can explain it is that it sounds like when a phono cartridge has a bad impedance mismatch with a preamp or if the signal gain is too high and it is clipping .  The unit only has less than 15 hours on it.  I wanted to know if this is normal and it would clear itself up or I have received a bad unit.  I have tried it in 2 different systems and it sounds the same. I have tried both outputs, balanced and unbalanced.  I have read this dac requires 100s of hours break in time and I hope the sound improves.  Anyone has any experience with this and could share their thoughts?  I would greatly appreciate it.

(Please don't take this as an insult but check to make sure the tag behind the power receptacle says 100V and not 120V. If it's an import they may have changed the xfmr)

The easiest way to see if there are problems with the unit is to check the voltage at each RCA output to make sure there is 2.5 Vrms.  

If the output voltage is correct then leave it powered on for at least 72 hours and then run a disc on repeat for 8 hours or so with the RCA outputs loaded to a preamp (off or on doesn't matter). What you hear after that should be very close to what the unit will sound like.
