I have recently purchased a squeezebox duo and absolutely enjoy the functionality of the device. If I want the best I'll play vinyl but for ease of use the squeezebox wins every time - CDs are now only played once to copy onto my external hard drive. At the moment I play my digital sources through a NOS DAC - blue light plastic box - It is good, very good but Id like to get more out of my source material like emotion, involvement and subtlety; the essence that communicates the emotion and connectedness of the music. Should I be considering a DAC upgrade?
