WebJan 27, 2024 · Linearity is not important unless a DAC has very poor linearity. Which few do. Crosstalk is almost never a real concern. LP's which can have good imaging never have better than 35 db crosstalk. It only takes about 18 db for good stereo separation. So a DAC with only 70 db crosstalk would be poor vs others, but still plenty in reality. simply flowers calne wiltshire
