I have used the 9.1 for this unit and was more than happy with them, due to my little girl damaging them I need to buy a new pair, only use this in the bedroom mainly for plays etc (4 extra that kind of thing) so bass not too important but really clear vocals is, don't want to spend to much and I can get the 9.1 for £100 or the Denon speakers for £70 and I do like the look of the Denon's and they both get really good reviews but which would you go for or any other recommendations ? (bookshelf size only), Thank you.
