Is there a difference?

[E-Stat]

Does this mean that the sound is 4 times better that my current amp, or it just has extra features etc. I am a bit confused on this as i cannot see how this would be feasibly possible.

Indeed better exists, but I think it is important to set a goal as to what you want to attain. Do you seek more headroom (power)? It appears by your system description that you run the F30s full range. Perhaps you should look into getting some powered sub woofers to add first octave bass to your system - which tends to be more important for HT systems.

BTW, i have no chance of getting into a decent demo room round these parts

That is unfortunate, because I've found it certainly helps to have a point of reference.
