I've been using a Peachtree DAC it with a Cal Audio as a back up set for some time. Little bit coarse sonically speaking but I did enjoy. Just replaced it with a Peachtree Sona dac. I use this unit in DAC only mode ignoring its pre-amp. It is much more detailed and smoother than the DAC it. Much better chip. Best of all since this unit wasn't overly popular I was able to get one very cheap! If I had wanted a dac with a pre-amp I would probably have gotten a different model for more $. Not sure how much better the chip would sound though.
