Rja and Calvinj, thank you for all that information. It is extremely helpful to me. I am excited about my audition of the DAC 4 in my system tomorrow. I will let you all know how it sounds. I am still struggling with whether to go with a separate DAC and transport or the one box piece. Assuming I like it, I could go with the DAC 4 and my current transport (Musical Fidelity A3.2). Then if I wanted to, I could get the Acute 4 transport later. Alternatively, the cheaper option would be to wait for the new one box player, but the timing of production and availability are not yet definite (hopefully before the end of the year).
