Thanks for the comments! A couple of friends who are audiophiles Helped guide me through my purchases. The system sounds fantastic. I listen to mainly jazz and classical music both of which sound great on this system. The highs and mids are incredibly pure on the speaker and the base is deep, full and tight. The vintage CAL Sigma DAC has an analogue like character that sounds better (on my system and to me) than other much more expensive DACs that I demo'd.
