All:Here  is the low-down on the Lite Audio DACs.
The Lite DAC-AH is the only Lite DAC that does not over sample.  A description of what it does can be found at www.pacificvalve.us
The Lite DAC 72 – forget it.  It uses an old Burr Brown chip, the PCM1702P-K.  This chip sounded bright and thin. Spend the extra money and get the DAC 60 which uses an excellent AD converter called the BB PCM 1704U-K. 
Now it gets even harder.  Recently there have been a number of DAC 60s out of Hong Kong outfits with the PCM1704U chip instead of the PCM1704U-K chip.  BIG difference between the two.
Then there is the DAC 68, and I have heard one and I am going to get one.  Incredible resolution and very smooth sound.  
There is more – there is also a DAC 38, and a DAC 39 Upsampler.  I do not know if Pacific Valve is going to carry these.
Phew!
