This is a related question to the use of the Toshiba as a CD transport. I am using the 990's DAC's by using the coaxial output of the Toshiba when playing CD's. Would it be better to use the Toshiba's DAC's by using the 2 channel analog output to the 990's 2 channel CD imputs. Which should sound better? I have been setting the 990 to bypass.
