Folks, I have the Luxman D03X and it sounds wonderful and I had been wondering about the D10X, so a little research and I found SMSL makes DACs and they have the MODEL NUMBER D300 which uses the same DAC chip ROHM BD34301EKV that is used in the Luxman D10X. 

I just got the SMSL D300 and I hooked it up to the Luxman 595ASE and oh boy.. I was pleasantly surprised how great this little DAC sounds through the system.. The SMSL D300 costs like $360.. I am shocked and amazed on how beautiful it sounds.. Kudos to SMSL!!
