Great discussion of the Oppo 105 - I've had mine for a few months now and love it.

Or to a really nice 5/7 ch multi-channel amp or a combination of both. I have a big 7 channel amp for the surround / back with spare channels for a future upgrade to 9.2 and bigger Bryston amps for the L/R front and center.

I have both system integrated into one. For stereo, using the 105's balanced outputs to feed a high quality balanced pre-amp which drives my L/R front Bryston amp. Also using the 105's 7.1 RCA outputs to feed the L/R Front HT bypass on the preamp and directly to the inputs on the center amp and multi-channel amp for multi-channel sound.
I guess you could call this a 'tweener' system, but it is really a "builder" system which will allow me to add a high-end surround processor down the road without throwing away anything. And because the 105 has reference quality DACs and balanced outputs, I don't need an external DAC which saved me at least $1000 - more than the cost of the upgrade from the 103.
My favorite thing about this type of system is the simplicity. The 105 is the hub of the system - it plays the discs and USB files, decodes the surround, and does it for both music and movies. My old system had a CD, DAC, DVD, Pre-pro, Preamp, and amps - nearly 30 connections. The new one only BD, Preamp, and amps and way less than 20 connections. Simple and sounds great!

Yes, to get more power than any AVR can deliver and to use external amps that are not embedded in an AVR which has to be upgraded every time there is a new surround format - historically about every 5 years. You can buy a high power / high current AVR, but they are very expensive, very heavy, and run hot - and those excellent amps are permanently connected to a surround decoder and video switcher that will be obsolete when the next disc format is released.
There are 100's of threads taking about hearing the difference between AVR amps and external amps - you can read them and have your own opinion. Just watch for the phrases "assuming equal power between the two" or "comparing similar power output" - it is always there. Nobody argues about the fact that more power makes a difference in the dynamics and the bass that you are going to hear - you don't even need a DBT to hear it. When you switch from a 100wpc AVR to a couple of 300wpc amps you won't believe what your speakers can do.
