Sorry for my eariler gush but...I really like the new setup!

I also tried the analog outs from the OPPO 103 vs the HDMI but couldn't really tell any difference...as long as you don't use Audessey with HDMI. Then there is a difference, you may like it or not, most people don't with music. The OPPO 105 has much better analogs for music.

As for setting use the following, a tape measure and an SPL meter...here you can run Audessey then use the measurements, note the subs are usually farther away than reality, so you'll need to measure these for the analog setup. Make sure you set all you speakers to "small" and crossovers to 1 octave higher than your speakers are rated, ie: if they say 40 to 20k then between 60 and 80 for your crossover....this will give you a good blend for bass. Once you have your speaker measured to the nearest .1 ft (from your listening position) use the spl meter to equal the other speakers to the front left speaker in volume. Do the same with your subs except don't set each to the same volume as the rest. Here you need to sum them, usually about - 3 or -4 bd each (to left front) will get you close. After that sit back and enjoy your music.
