is it possible to make digital audio sound like vintage vinyl
You can get it to sound much closer to older recorded vinyl richer sound, especially with early digital that were remastered to give that shocking pseudo ping pong stereo effect.
The output of the dac or cdp you use will be more than >100db channel separation, you’ll need to "kill this down" with a left to right bleed passive/or active network to "mimic" vinyl’s best of 35db in the midrange, and best 12db at highs and almost mono at lows.
Here is the best channel separation a Lyra Dorian cartridge can do https://ibb.co/Vtm8bNx this if it’s done to a digital output will richen things up especially at the extremes as they get mono’ized for want of a better word.
