I got my Luxman DA-06 today. Right off the bat it sounds great, I can't wait till it breaks in. It is extremely analog sounding. It is smooth, liquid, musical and has just the right amount of warmth. There is no glare, harshness or digital edge. It clearly is not a Sabre based DAC so if you are looking for that false clean crispness, this is not the DAC for you. The midrange has weight, depth and transparency. I am surprised that more people don't own this DAC. It is a perfect match for my system. It even reduces ssssibilantsss. Bass is tight, powerful and deep. Vocals sound natural and are just minimally forward. The sound stage is wide with good air. Cymbals sound natural and detailed. There is excellent spacing between instruments.
Right now I am listening the Power Of One by Paul de Benedicts from my CDP via digital coax. The piano is so natural sounding. The notes have fullness and air at the same time. I wish that I did not have to work the next 5 days or I would be planted in my sofa drinking wine and listening my music collection.
I briefly had the Marantz NA-11s1 and the new Cary Audio 200t and this DAC is in another league.
