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.

100s of hours is what I read on forums with owners of the DA-06, not sure what Luxman's policy is regarding burn in.  Ive had very good luck with gray market imports.  There is no reason for me to believe that this is a counterfeit.  The build quality is outstanding, came with paperwork, and the insides are genuine.  Yes, I opened it up and took a good look inside.  Heck if this was a counterfeit, why would they waste their time doing that when they could be designing their own equipment because they are that good!

Wouldn't surprise me if that step down wasn't killing the music....

If it was me, I would see about sending it in to Luxman to get the right transformer put in it for your voltage requirement.

Yeah I read much about using step down transformers.  Some say it degrades the music quality others say it increases it.  There are several transformers from the plant to my home, not sure why another one would degrade the quality.  I dont see how but I could always put a scope to the 100v to see if there excess noise or a distorted waveform.  I will do that during the week, we have some nice Tektronix scopes at work.

You can’t compare the power grid setup to what you have there. It is all about having low impedance power delivery for digital gear IME, so that transformer really cannot help things.... You need fast current delivery for these high speed digital devices.

Thats why all those caps are there for.  I completely agree that digital devices need very high speed instantaneous current delivery.  With the small power draw of the dac, I bet that those big luxman caps are never completely drained.  

I just did a compairson with my old Onkyo  C-S5vl player.  The Luxman sounds a bit better after about 20 hours of use when I compare it to the Onkyo (which sounds low end to my other dacs).  Im also using this Onkyo to loop a cd continously.  The Luxman still isnt anywhere near the level of what it should produce however.
