Does anyone have any background with this DAC/preamp/ I am considering adding this to my system. Peachtree amp 500/new predac preamp also from Peachtree. Double Impact speakers and audiolab 6000CDT Also stream Amazon HD via USB from Computer. Was told it would make an exceptional preamp/DAC , better than current preamp. However, just wondering if paired with the peachtree set up in a pure DAC only mode what the sonic benefits would be, or not be? Any assistance would be great. Thanks Robert TN
