Ah!! the audio bug might be biting again. My present 2 channel system consists of: A Conrad Johnson PV14L tube preamp, Van Alstine OmegaStar440EX amp, Consonance CD120 upsampling CD player, & AAD 2001 monitors. Now don't get me wrong, I really do like the way my system sounds, but it's just been buging me about this DAC issue. Do you think a DAC would benefit me & in what way? What are your experiences? What DAC's have you used & how did they perform? My budget is maxed out at $1800. Hopefully your info will allow me to make an educated decision.
