Hi, due to budget constraints i may have to use a pair of tannoy R1s as front speakers with some even older kef coda 7s as rears...........to this i am going to add a tannoy center (to keep the fronts all one make) and an onkyo reciever (506/576 or 606 not sure which).........later on i need to add a sub, should i stick with tannoy or can i mix???? or should i forget the whole idea and go for somthink like the jamo £200 speaker set?
