For me the analog out quality sucked . There was a constant high pitched whining that was more evident at high volumes and clearly audible while listening to talk/comedy or music like classical. Not to mention a constant low pulsating thumping noise, but that was only apparent when I put the PCR on mute but kept my head unit at high volume. Also it was muffled and wasnt very crisp or vibrant.
The optical out fixed all that, but that added $150+ to the total cost since I had to get a sound card with optical input.
