It's almost like having a good mixing board,with the right speakers,it sounds live!!!

None that I know of but,who am I to say,lol

Very functional with many features in multi speaker mode, but in stereo plane mode, is not better than other products. The voices are some in the background when playing whit other frecuencies.
I suggest to everyone who wants to change his amplifier to this model, not do that or keep both amplifiers. One for stereo, other for Dolby.
Perhaps, other model be better in stereo mode. I compared this model with a Pionner SA5500II an TAF3 SONY-ES. Both better in stereo
