WQhat I find to be a real problem with these changers is the time between discs. maybe they have solved this since my last encounter, but from my recollection, when you select a new disc, it cuts out the currently playing track, and then searches for the next disc. This takes time,, dead space. I would think that they could come up with a RAM buffer system that continued the current playin track until the next disc was ready to play, and then have an option of either a clean start, or a Xfade transition
