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.

I have heard a Luxman DA-06  from an authorized dealer in the US so its voltage was set to the US 115v standard. Using the DA-06 out of a Macbook Pro computer up sampling to DSD using JRiver Media 21, the DA-06 has different digital filter settings that may have an effect upon sound. My advice: You may achieve better results depending upon the digital signal sent from your computer which may be impacted by the cable (I heard a USB) and the filters. Maybe the step down converter has a deleterious effect that none of these factors may overcome but with the US version, the DA-06 produces a great result. Try different filter settings, cables, high resolution PCM and conversion to DSD before you give up. You may get a great result if you can try these things.

Check out the threads on step down transformers as there is a plethora of info on them. One member in particular, renjy651, has a lot of experience with them regarding model types, switch outs, and the like.

All the best,

IMO, all this trendy mix and match DAC stuff with assorted degrees of crap accessories is quite pointless unless your pursuit is pure functionality alone.   For great sound, a one box source and simplified amplification stage with quality cables/cords into highly dynamic speakers will yield better results.  Computers and DACS and converters...why?  Sit down, put on a great disc and turn out the lights.  Relax then repeat!

Dave,
I think you are right. That is why I changed from a Spectral / dcs set to an all Nagra set: CD player, pre and power. No guess work involved. Still, Audioman, I hope you get things sorted out: contact Luxman and accept the costs if there are any. Good luck!

The US distributer " On a Higher Note" won’t touch a Grey market player with a ten foot pole. The OP is bound to the the country of origin for any service/support needs. If the player is legit Luxman, and no reason to believe it’s not. Then be patient for the player to break-in. Luxman is a great brand...sit back and enjoy.
