Which shelf or mountable speakers for Onkyo 606

[bullitt]

Which shelf speakers would you recommend to go with my Onkyo 606 ? I currently have Tannoy mercury F1 speakers but I don't want to replace with speakers that are not as good , also I have an MJ acoustics 100 mk2 sub, would I need to change that too ? Thanks

Would the Q Accoustics 2000i be a good match with my Onkyo 606 ? any help would be appreciated.

Thanks
