Timiteo, I think the point everyone is making, and it's the main point here, is that your amp cannot drive those speakers. 120 w into 4ohms for those large panels is very under-powered. The range and dynamics are greatly restricted due to the lack of power, especially bass.
All of your sources will wake up if you get a more powerful amp. I don't think the IIIa will really wake up with anything less than 300w into 4ohm, and more better.
