When the next song starts, it takes about 1-2 seconds to re-establish the connection (i.e., for the indicator lights come back on on the preamp) and so I don’t hear the first second or so of that next song. The problem is that at the end of every song, it seems like the Mac Mini stops sending the audio signal to the preamp during the “gap” between songs, as evidenced by the L/R audio input indicator lights on the front of the preamp going out. I am using a brand new Mac Mini (4GB RAM running OS 10.6.5) to run primarily FLAC audio tracks to my stereo system’s preamp, a McIntosh MX132 via the TOSLINK digital audio out.
