DAC chips age well, in fact many of the best DACs made today employ old chips. My personal favorite is the CAD 1543 MK ii which uses 16 of the old Philips 1543 chips.
Advances in understanding of power supply isolation, usb integration, and EMI/RFI, mean that new DACs using the old chips is often the sweet spot.
