Have the OPPO 105 going on 5 mos., running in a 2ch system, no video. You will need a screen to setup(computer monitor works fine), set your OPPO, disconnect from monitor, put into your system and you're off to the music. It does take a long time to break in, but it's worth the wait. Figure at least 100hrs. It's very revealing of the disc you play, good is great, so-so just that or bad. You get a picture of what's there, the good, bad & the ugly. One of the best bargains around. Enjoy the music!
