I dont know how much you are willing to spend Sir but as you said you listen most to rockmusic - I am a rock lover too - then I definitely recommend you to listen to a pair of q3. If you are intending to buy a new pair s5 then an exdemoed or used-as new pair of q3 would be far more superior to you.
I am using the q5 and everyone who heard they play rock music was stunned about the dynamic and lifelike presentation. I did listen to the rockport akkaris mk2 but I do not really like the 'big sounding' of those speakers although they are truly superb.
I have not heard the avior so dont know how they sound.
So as many others pointed out, home audition is the best for you to decide which ones are the most relevant speakers.
