I am stuck in the old analogue world with a 2 channel Bryston pre amp and amp and a dvd cd player and don't understand the need for DAC's and all that stuff. Please enlighten this old geezer.
Your CD player actually has a DAC in it. It takes the 0's and 1's (bits) from your CD's and coverts it to an analogue signal your pre-amp/amp can understand.
